Description

[Technical Field]

[0001] The present invention relates generally to the field of multi-cloud environments, and more specifically to blockchain-enabled secure quantum key distribution (QKD) block data movement in storage clouds.

[0002] Emerging technologies for the quantum computing era are using quantum mechanics in a variety of computing environments. One popular technology is quantum key distribution (QKD), a secure communication mechanism used as a cryptographic key sharing platform that employs quantum mechanics. Generally, QKD generates a shared, random, secret key known only to the secure parties, which can then be used to encrypt and decrypt messages. This mechanism generates a secure key using photon transmission and sends the generated secure key to an endpoint. As the photon stream is transmitted, identical keys are generated at one or more end devices. Note also that QKD uses symmetric key encryption. A unique property of QKD is the ability of two or more communicating users to detect the presence of any third party attempting to gain knowledge of the key. Third-party detection is a result of a fundamental aspect of quantum mechanics: the process of measuring a quantum system generally perturbs the system. Therefore, a third party attempting to intercept the key would need to measure the quantum system in some way, thereby resulting in a detectable anomaly. By using quantum superposition or quantum entanglement to transmit information in quantum states, a communication system can be implemented that detects eavesdropping. If the level of eavesdropping is below a certain threshold, a key can be generated that is guaranteed to be secure (i.e., an eavesdropper does not contain information about it). This enables a secure mechanism for generating symmetric keys across end devices, providing the functionality of symmetric key encryption across cloud components. Additionally, modern cloud storage systems use asymmetric key encryption due to limitations in secure key transmission. Summary of the Invention

[0003]

[0009] Embodiments of the present invention disclose a method, computer program product, apparatus, and system for detecting data corruption between storage systems, the computer-implemented method comprising performing information tunneling for data transfer between a source storage system and a target storage system. Further, the embodiments determine that checksum data of the data payload does not match an Internet Protocol (IP) packet-extracted checksum and a block-chain-based checksum, and compare the checksum data at the target storage system with the IP packet-extracted checksum and the block-chain-based checksum to identify one or more checksum mismatches. Additionally, the embodiments identify corruption in the data payload based on a comparison between the checksum data at the target storage system and the IP packet-extracted checksum and the block-chain-based checksum. Finally, in response to receiving a predetermined number of checksum mismatches that trigger a security breach isolation requiring corrective action, the embodiments verify the corruption in the data payload; and update an entity for each identified corruption in the data payload.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Embodiments of the present invention recognize that there are deficiencies when using symmetric key encryption in cloud storage systems. One problem that embodiments of the present invention recognize is that symmetric key encryption cannot be directly used in secure block storage migration due to cloud infrastructure orchestration and Ethernet routing.

[0012] In one example, consider storage virtualization engines deployed on different cloud systems (e.g., a first cloud system and a second cloud system) that support host application input / output (I / O) delivered to a storage system and replicate the host application I / O to a secondary storage cluster in the second cloud system. In this example, when I / O is received by the primary storage virtualization engine cluster, the I / O is replicated to a second database cluster (which may be located on the same cloud or a different cloud system) to provide disaster recovery and data availability in the event of a failure of one of the storage systems. In this case, if in-flight data encryption is used, current technology performs asymmetric key encryption, which involves a public-private key pair and encrypts the data before transmission over the network. Once the encrypted data packets reach their designated location, they are decrypted using an asymmetric method, and the cleartext packet payloads are further processed and stored in persistent block storage devices. These persistent block storage devices are connected to the virtualization engine as back-end controllers.

[0013] In one example, if a QKD mechanism is available between the source and target storage system locations, the QKD mechanism ensures secure transmission of keys between those locations. This allows for symmetric key encryption, which is more efficient and requires less central processing unit (CPU) computing power. In this example, the use of symmetric key encryption across cloud-located storage engines creates a potential security threat when the storage system uses transport mode encryption. In transport mode security, the data payload is encoded, but the Internet Protocol (IP) headers are not modified or encrypted, leaving routing intact. In a cloud environment of storage controller systems, routing remains intact, supporting the underlying cloud orchestration migration and transparency mechanisms. Therefore, embodiments of the present invention recognize that transport mode encryption is recommended for cloud instances of storage systems with IP header defects. Embodiments of the present invention recognize that IP headers are not encrypted, posing a potential threat of modifying the encrypted block data payload and altering the IP header for cyclic redundancy check (CRC) and checksum values ​​of the modified (corrupted) payload. In this scenario, if the payload is corrupted and the checksum is updated appropriately, embodiments of the present invention recognize that there is no known way to detect this type of data corruption.

[0014] Additionally, embodiments of the present invention recognize that corrupted data is stored at the target location, which can pose several challenges. Furthermore, embodiments of the present invention recognize that known techniques exist that can corrupt IP payloads and update IP packets for CRC and checksum values, which can cause block data corruption in storage replication. Embodiments of the present invention recognize that the problems outlined above exist when symmetric key encryption is used between storage system instances in a cloud. For example, two storage controllers are located between different clouds, and replication is configured between two storage instances across different clouds. When symmetric key encryption is used in transport mode, the payload is encrypted using the same key that is used to decrypt the data. If the IP packet is corrupted and the header is updated accordingly, the result is that there is no way to detect data corruption.

[0015] Furthermore, embodiments of the present invention recognize that currently, there are no methods for detecting block-based in-flight data corruption in asymmetric key encryption and no measures that can be taken against such data corruption within storage environments. Embodiments of the present invention recognize that adoption of symmetric key encryption is very low due to the unavailability of infrastructure for secure key transmission. Embodiments of the present invention recognize that detecting the specific problem described above is currently difficult, and that this represents a challenge in the art because future requirements for emerging cloud technologies require symmetric key transmission. Embodiments of the present invention recognize that with the enablement of QKD mechanisms in cloud storage, as described above, and storage engine instances in the cloud, emerging technologies will begin to adopt symmetric key encryption due to its relatively low CPU cycles. Embodiments of the present invention improve upon the current state of the art by detecting data corruption in transport mode encryption of block storage in Ethernet-based cloud systems.

[0016]

[0006] Embodiments of the present invention operate on top of QKD-based key distribution for cross-cloud data encryption. The present invention provides a mechanism for QKD and its enablement in cloud infrastructure. The present invention improves upon the state of the art by enabling cloud storage systems to use symmetric key encryption via QKD, which is less CPU-intensive and adds performance benefits to storage systems. The present invention provides a method, system, and apparatus that operates within a generic, cloud-located storage virtualization system and solves the above-mentioned problems by providing an efficient way to protect data from corruption during replication across cloud storage engines.

[0017] Embodiments of the present invention solve the above-mentioned problems and improve the art by (i) detecting data corruption and avoiding data loss across cloud storage sites during replication; (ii) implementing cost-critical data protection with state-of-the-art robust blockchain techniques to enhance the cloud story; (iii) enabling the use of symmetric key encryption across block storage systems deployed in cloud infrastructure; (iv) supporting symmetric key encryption using QKD mechanisms within storage systems to improve system encryption performance; (v) providing enhanced security for transport mode encryption to enable cloud-based data encryption using the cloud; (vi) preventing / avoiding data corruption during secure transport mode IO traffic across block storage systems; (vii) operating at reduced cost; and (viii) dynamically adjusting operation at various levels to optimize system performance.

[0018] Implementations of embodiments of the present invention may take a variety of forms, and details of exemplary implementations are discussed below with reference to the figures (ie, FIGS. 1-7).

[0019] The description of various embodiments of the present invention is presented for illustrative purposes and is not intended to be exhaustive or limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the invention. The terms used herein have been selected to best explain the principles of the embodiments, practical applications, or technical improvements over commercially available technologies, or to enable others skilled in the art to understand the embodiments disclosed herein.

[0020] Although this disclosure includes detailed descriptions of cloud computing, it is understood in advance that implementation of the teachings recited herein is not limited to a cloud computing environment. Rather, embodiments of the present invention can be implemented in conjunction with any other type of computing environment now known or later developed.

[0021] Cloud computing is a service delivery model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with the service provider. The cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

[0022] The characteristics are as follows:

[0023] On-Demand Self-Service: Cloud consumers can unilaterally provision computing capacity, such as server time and network storage, automatically as needed, without requiring human interaction with the provider of the service.

[0024] Wide network access: Capabilities are available over the network and accessed through standard mechanisms that facilitate use by heterogeneous thin or thick client platforms (e.g., cell phones, laptops, and PDAs).

[0025] Resource Pooling: Provider computing resources are pooled to serve multiple consumers using a multi-tenant model, with various physical and virtual resources dynamically allocated and reallocated in line with demand. Consumers generally have no control or knowledge over the exact location of the resources provided, although there is a type of location independence in that they may be able to specify location at a higher level of abstraction (e.g., country, state, or data center).

[0026] Rapid scalability: Capacity is provisioned quickly and elastically, sometimes automatically, and can be instantly scaled out or quickly released and instantly scaled in. To the consumer, the capacity available for provisioning often appears unlimited and can be purchased in any quantity at any point in time.

[0027] Metered Services: Cloud systems automatically control and optimize resource usage by leveraging metering capabilities at a level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency to both providers and consumers of utilized services.

[0028] The service model is as follows:

[0029] Software as a Service (SaaS): The consumer is offered the ability to use a provider's applications running on a cloud infrastructure. The applications are accessible from a variety of client devices through a thin-client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure, including the network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

[0030] Platform as a Service (PaaS): The ability offered to consumers is to deploy applications they create or acquire, written using programming languages ​​and tools supported by the provider, onto a cloud infrastructure. The consumer does not manage or control the underlying cloud infrastructure, including networks, servers, operating systems, or storage, but does have control over the deployed applications and, in some cases, the application hosting environment configuration.

[0031] Infrastructure as a Service (IaaS): The ability provided to consumers is to provision processing, storage, network, and other basic computing resources onto which they can deploy and run any software, which may include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure, but does have control over the operating systems, storage, deployed applications, and in some cases, limited control over selected networking components (e.g., host firewalls).

[0032] The deployment model is as follows:

[0033] Private Cloud: Cloud infrastructure is operated solely for the organization. It may be managed by the organization or a third party and may exist on-premise or off-premise.

[0034] Community Cloud: Cloud infrastructure is shared by multiple organizations to support a specific community with common interests (e.g., mission, security requirements, policies, and regulatory compliance considerations). It may be managed by those organizations or a third party and may exist on-premises or off-premises.

[0035] Public Cloud: Cloud infrastructure is made available to the general public or large industry organizations and is owned by organizations that sell cloud services.

[0036] Hybrid Cloud: Cloud infrastructure is a combination of two or more clouds (private, community, or public) that remain distinct entities but are bound together by standardized or proprietary technologies that allow for data and application portability (e.g., cloud bursting to load balance between clouds).

[0037] Cloud computing environments are service-oriented with an emphasis on statelessness, low coupling, modularity, and semantic interoperability. At the core of cloud computing is an infrastructure that includes a network of interconnected nodes.

[0038] Referring now to FIG. 1 , an exemplary cloud computing environment 50 is shown. As shown, the cloud computing environment 50 comprises one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, a personal digital assistant (PDA) or mobile phone 54A, a desktop computer 54B, a laptop computer 54C, and / or an automobile computer system 54N, may communicate. The nodes 10 may communicate with each other. They may be physically or virtually grouped (not shown) in one or more networks, such as a private cloud, a community cloud, a public cloud, or a hybrid cloud, or combinations thereof, as described above. This allows the cloud computing environment 50 to provide infrastructure, platform, and / or software as a service for which cloud consumers do not need to maintain resources on their local computing devices. It is understood that the types of computing devices 54A-54N shown in FIG. 1 are intended for illustrative purposes only, and that the computing nodes 10 and the cloud computing environment 50 may communicate with any type of computerized device over any type of network and / or network-addressable connection (e.g., using a web browser).

[0039] Referring now to Figure 2, a set of functional abstraction layers provided by cloud computing environment 50 (Figure 1) is shown. It should be understood in advance that the components, layers, and functions shown in Figure 2 are intended to be exemplary only, and embodiments of the present invention are not limited thereto.

In one example, these resources may include application software licenses. Security provides identity verification of cloud consumers and tasks, as well as protection of data and other resources. User portal 83 provides access to the cloud computing environment for consumers and system administrators. Service level management 84 provides cloud computing resource allocation and management so that required service levels are met. Service level agreement (SLA) planning and fulfillment 85 provides proactive provisioning and procurement of cloud computing resources that anticipate future requirements according to SLAs.

[0045] Network 130 may be, for example, a storage area network (SAN), a telecommunications network, a local area network (LAN), a wide area network (WAN) such as the Internet, wireless technologies for exchanging data over short distances (from fixed and mobile devices, using short-wavelength ultra-high frequency (UHF) radio waves in the 2.4-2.485 GHz Industrial, Scientific, and Medical (ISM) band, creating a personal area network (PAN), or a combination of the three), and may include wired, wireless, or fiber optic connections.

In other embodiments, server 110 and server 120 may each represent a server computing system utilizing multiple computers, such as, but not limited to, a server system as in a cloud computing environment. In another embodiment, server 110 and server 120 may each represent a computing system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that function as a single pool of seamless resources when accessed within distributed data processing environment 300. In various embodiments of the present invention, server 110 and server 120 may be physical or virtual servers and / or any other servers known in the art. Server 110 and server 120 may each include internal and external hardware components, as shown and described in further detail with respect to FIG. 7 . In some embodiments of the present invention, server 110 and server 120 may each represent multiple server computers. In various embodiments of the present invention, server 110 and server 120 may each be a system of server computers.

[0051] In the illustrated embodiment, server 110 includes storage system 111 represented by cloud 170, and server 120 includes storage system 121 represented by cloud 172. Storage system 111 is connected to node 113.1-N , and the following node 113. Similarly, storage system 121 includes node 123 1-N , and node 123. As used herein, N represents a positive integer, and therefore the number of scenarios implemented in a given embodiment of the present invention is not limited to those shown in FIG. 3 . Nodes 113 and 123 may be one or more storage nodes having one or more hard disk drives (HDDs) or solid state drives (SSDs). A storage node may also be a virtual machine or virtual logical unit number (LUN) having access to one or more HDDs and / or SSDs. In some embodiments, nodes 113 and 123 may be one or more virtual storage nodes. In various embodiments, server 110 constitutes cloud 170 via node 113, and server 120 constitutes cloud 172 via node 123. Clouds 170 and 172 may be cloud environments capable of cloud storage and / or cloud computing. In various embodiments of the present invention, clouds 170 and 172 may be any cloud environments known in the art.

[0052] In the illustrated embodiment, nodes 113 and 123 communicate with a blockchain ledger architecture (ledger architecture) 140. In various embodiments of the invention, nodes 113 and 123 record transactions (e.g., data transfers or replications) on a blockchain 144 and store the transactions in a ledger state database 142. Blockchain 144 is a blockchain as known and understood in the art. Blockchain 144 provides a secure mechanism for storing data, allowing blockchain payload data to be collected at a target destination. Because checksum data is stored as part of the blockchain payload, the checksum data cannot be comprehensibly readable and is protected from security breaches. Ledger state database 142 is a blockchain-based database or any database as known and understood in the art. Blockchain 144 may comprise a consensus network (consensus network 160) as shown in FIG. 5A. Consensus network 160 is a fault-tolerant mechanism used in computer and blockchain systems to reach the necessary agreement among distributed processes or multi-agent systems on a single data value or single state of the network.

[0053] Each of nodes 113 and 123 may comprise a data / knowledge repository and / or database that may be written to and / or read by one or a combination of components 122, server 110, server 120, computing device 102, and / or computing device 101. Each of nodes 113 and 123 may comprise any type of storage device implementation capable of storing data and configuration files that may be accessed and utilized by server 110 and / or server 120, such as, but not limited to, a database server, a hard disk drive, or flash memory. In some embodiments of the present invention, each of nodes 113 and 123 may comprise a hard drive, a memory card, computer output to a laser disk (cold storage), and / or any other form of data storage known in the art. In various embodiments, each of nodes 113 and 123 may access, store, and / or contain user data, physical room data, and meeting data, and / or data shared across distributed data processing environment 300.

[0054] In the illustrated embodiment, component 122 executes on storage system 111 within server 110. In other embodiments, component 122 may execute on storage system 121, computing device 101, or computing device 102. In various embodiments of the present invention, although not shown in FIG. 3 , component 122 may execute on multiple servers 110, multiple servers 120, multiple computing devices 101, and / or multiple computing devices 102. In some embodiments, component 122 may be located and / or execute anywhere within distributed data processing environment 300, so long as component 122 is connected to and / or in communication with computing device 101, computing device 102, quantum device 103, quantum device 104, server 110, and / or server 120 via network 130.

[0055] Component 122 may use symmetric key encryption mechanisms to detect data corruption and block-level I / O replication from the source storage system (e.g., storage system 111 and / or storage system 121) to the target cloud instance. In various embodiments of the invention, component 122 generates secure symmetric keys between the source and target systems using QKD, which may be used for in-flight data replication. For example, storage system 111 (the source system) receives an instruction to send data to storage system 121 (the target system). In this example, component 122 generates secure symmetric keys between storage system 111 and storage system 121 to secure data transactions between storage system 111 and storage system 121. In various embodiments of the invention, component 122 discovers the physical location of the storage instance in the cloud (e.g., cloud 170 or cloud 172), gathers information from underlying received quantum keys (e.g., quantum key 116 and quantum key 118), and uses the gathered quantum keys to store, maintain, and encrypt data.

[0056] In various embodiments of the invention, component 122 encrypts one or more packet payloads within an Ethernet packet frame, keeping routing intact for efficient path traversal of block data across clouds 170 and 172. Component 122 may calculate a checksum of the data payload for an Internet Protocol (IP) packet and request submission to a blockchain ledger (e.g., blockchain 144) along with the IP packet serial number (ser_no) and checksum. In various embodiments of the invention, component 122 stores the checksum data as a payload on blockchain 144 via ledger state database 142, and the stored checksum can be requested by a target system.

[0057] In various embodiments of the present invention, component 122 provides an inbound or out-of-bound application programming interface (API) infrastructure for communication between QKD devices (e.g., quantum device 103 and quantum device 104) and block storage instances in the cloud based on physical device identification. Additionally, component 122 may perform information tunneling, as appropriate, for data transfer between storage system 111 and storage system 121 using the enabled communication described above.

[0058] In various embodiments of the present invention, component 122 transmits data to a target location via a cloud infrastructure network (e.g., replication link 115) using quantum key transport mode encrypted packets. Component 122 compares checksum data at the target system with the IP packet extracted checksum and the blockchain-based checksum to determine whether the checksum data matches the stored IP packet extracted checksum and the blockchain-based checksum. If component 122 determines that the checksum data matches the IP packet extracted checksum and the blockchain-based checksum, component 122 decrypts the data payload checksum match. However, if component 122 determines that the checksum data does not match the IP packet extracted checksum and the blockchain-based checksum, component 122 issues a data SEND_FAILURE, initiating a retransmission because the original data is corrupted. In various embodiments of the present invention, component 122 detects and identifies the level of corruption in the data and updates the respective entities of the detected and identified data accordingly.

[0059] In various embodiments of the invention, component 122 utilizes existing blockchain payloads to reduce checksum overload on the blockchain and performance efficiency, and checksum deduplication via blockchain 144. To improve the selective quality of service data replication, component 122 may send checksums via the blockchain ledger (e.g., blockchain 144) for specific specified objects, sets of objects, or inherited objects that it traverses. In various embodiments of the invention, component 122 enables selective secure (e.g., ultra-secure) replication as a service via the cloud (e.g., cloud 170 and / or cloud 172) and configuration analysis before performing secure checksum verification. In various embodiments of the invention, component 122 provides communication service provider (CSP) interconnection for collecting, extracting, and verifying configuration changes in subscriptions to checksum verifier objects. In some embodiments, component 122 activates new symmetric keys, initiates replication traffic using the new keys, and accordingly enables symmetric key encryption based on the collected, extracted, and verified configuration changes.

[0060] 4 illustrates a node architecture of nodes 113 and 123, generally designated 400, in communication with computing device 101, computing device 102, server 110, server 120, and / or blockchain 144 in distributed data processing environment 300 of FIG. 3 according to one embodiment of the present invention. FIG. 4 provides an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the illustrated environment may be made by one skilled in the art without departing from the scope of the invention as recited by the claims.

[0061] In the illustrated embodiment, the virtualization engine 402 in the cloud represents a node (e.g., node 113 and / or node 123). In the illustrated embodiment, virtual machine (VM) 1081-N , hereafter VMs 108 contribute to the node. As used herein, N represents a positive integer, and thus the number of scenarios implemented in a given embodiment of the present invention is not limited to those shown in FIG. 4. VMs 108 enable application deployment and issue block storage I / O requests to a storage target system (e.g., storage system 121). VMs 108 are virtual machines as they are known and understood in the art. In the illustrated embodiment, the node includes a blockchain API 152, a packet generator 153, an IP header checksum mapper 154, a symmetric key store 155, a checksum uploader 156, a QKD interconnection API 157, a CSP interconnection API 158, and a metadata mapper 159, which communicate via a platform mapper queue 151. In the illustrated embodiment, block API 152 communicates with blockchain consensus network 160, relaying data to and from blockchain consensus network 160, which comprises blockchain 144 and / or ledger state database 142. In various embodiments of the invention, blockchain API 152 enables data communication and storage to blockchain consensus network 160. In various embodiments of the invention, symmetric key store 155 enables storage of active and previously used generated keys, and key store 155 directs storage of symmetric keys on the blockchain consensus network and / or connected backend block storage 162. Further, in the illustrated embodiment, IP header checksum mapper communicates with connected backend block storage 162, relaying data to and from connected backend block storage 162. Additionally, in the illustrated embodiment, QKD interconnection API communicates with QKD endpoint devices, relaying data to and from QKD endpoint devices.

[0062] For example, node 113 may have various layers of an I / O processing stack, one of which is replication, and the replication layer addresses the requirements and processing of an I / O state machine for maintaining a consistent copy of a replication-enabled volume at the storage level. In one or more embodiments involving a replication-enabled storage system, the replication-enabled storage system has at least two endpoint devices, one at each storage system. Node 113 may typically include a packet generator (e.g., packet generator 153) that generates replication network packets at the source storage system for write replication purposes and sends them over a network (e.g., network 130 or replication link 115). In this example, a symmetric key generator creates a key used for packet encryption before the replication network packets are sent over the network. In this example, when the target storage system collects the packets, the replication target system (i.e., the target storage system) decrypts the collected packets using the generated key and submits the packets to a target replication manager, which manages and executes the next set of I / O completion operations.

[0063] 5A and 5B are functional block diagrams illustrating a distributed data processing environment, generally designated 500, for detecting data corruption between storage systems, according to one embodiment of the present invention. As used herein, the term "distributed" refers to a computer system that includes multiple physically separate devices that operate together as a single computer system. 5A and 5B provide an illustration of one implementation and do not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the illustrated environment may be made by one skilled in the art without departing from the scope of the invention, which is recited by the claims.

[0064] In various embodiments of the present invention, in a public cloud implementation of a storage virtualization system (e.g., storage systems 111, 121 and clouds 170 and 172), when replication is configured between instances of a storage system (e.g., storage system 111 and / or storage system 121) for disaster recovery or high availability of block data, I / O traffic is sent on replication link 115 across storage controller engines in storage system 111 and storage system 121 in clouds 170 and 172, respectively. A QKD mechanism may generate one or more secret keys at the source and target storage systems (e.g., storage system 111 to storage system 121, respectively) via quantum device 103 and quantum device 104, and once quantum keys (e.g., quantum keys (QK) 116 and QK 118) are generated at their respective locations, the storage systems use symmetric key encryption (e.g., key 210 and key 220). In various embodiments of the present invention, when storage system 111 or storage system 121 decides to replicate data from storage instance X to Y, the QKD API is invoked. The QKD API (e.g., QKD interconnected API 157) shown in Figure 4 is responsible for obtaining the physical locations of the source and target within the cloud infrastructure and communicating with the QKD endpoint devices (e.g., server 110, server 120, computing device 101, and / or computing device 102).

[0065] In various embodiments of the invention, once base locations are identified for both storage system 111 and storage system 121, a QKD mechanism is initiated, which then generates secure keys (e.g., key 116 and key 118) at both endpoints. In various embodiments of the invention, once secure keys are generated, replicated block-level I / O traffic (traffic 119) is transmitted via data encryption over replication link 115 and QKD link 105 between storage system 111 and storage system 121. In various embodiments of the invention, component 122, not shown in FIGS. 5A and 5B, stores the received data after decryption on storage system 111 and / or storage system 121 via SSD 502, SSD 512, HDD 504, HDD 514, near-line storage 506, and / or near-line storage 516. In various embodiments of the invention, the storage function is predetermined. In other embodiments, the storage function is customizable. In various embodiments of the present invention, due to transport mode encryption on the block storage system, component 122 encrypts the payload using a key (e.g., key 116 or key 118) generated by the QKD network. In various embodiments of the present invention, because routing and other IP packets are not encrypted, they can potentially modify the payload and update IP headers to corrupted values. To mitigate corruption, component 122 can enable a mechanism for storing checksum data on blockchain 144 before sending data packets over network 130 (e.g., sending IP packets as traffic 119 over replication link 115), which mechanism, via component 122, generates a checksum of the packet payload, embeds the checksum in the packet, and stores the data on the ledger for target system read purposes.

[0066] Checksums comprise little or no data, typically a few bytes per packet, so it is beneficial to store IP packet checksums as part of the blockchain payload. When a data packet reaches its destination, the IP header is extracted and the checksum value is compared to a value submitted to a blockchain ledger (e.g., blockchain 144). In various embodiments of the invention, if malicious activity is detected or occurs within the IP packet, the blockchain payload checksum and the IP packet checksum will not match and data corruption will be detected. If the checksums match the IP header and blockchain payload, the data is decrypted and further processing is performed on the data.

[0067] Component 122 may select blockchain-enabled payload validation for symmetric QKD encryption mechanisms deployed as a service model. In various embodiments of the present invention, a specific object or a set of inherited object sets is subscribed to for enhanced security mechanisms in transport mode encryption. In one embodiment, selected replicated I / Os that belong to the set of subscribed services and use transport mode are tagged to store checksum values ​​in the blockchain payload. This service model enables configuration-based decision-making capabilities for storage systems (e.g., system 111 and storage system 121) installed in a cloud (e.g., cloud 170 and / or cloud 172) for additional security in combination with the QKD mechanism. Furthermore, in various embodiments of the present invention, if frequent checksum mismatches trigger a security violation quarantine requiring corrective action, component 122 verifies the blockchain payload for corruption. The verification comprises component 122 requesting checksums via ledgers of applications that component 122 has been granted access to and / or execution, and performing checksum verification in the header and ledger. If a difference is found, the packet is dropped.

[0068] In various embodiments of the present invention, communication between cloud storage engine instances is performed using either a separate out-of-band protocol or reserved fields in the write CDB (SCSI CDB). In some embodiments, both the out-of-band protocol and reserved fields function as layers within the same storage controller and communicate information across layers.

[0069] In various embodiments of the present invention, a SCSI Command Descriptor Block (CDB) mechanism may be used to implement an inbound or out-of-bound API for communication across modules of the proposed system, where the CDB is used to exchange commands across components that are based on the SCSI standard and typically consist of 6, 10, 12, or 16 bytes. However, the communication method may vary based on the implementation design aspects of the appliance environment.

[0070] 6 illustrates the operational steps of a component 122, generally designated 600, in communication with servers 110 and 120 in distributed data processing environment 300 of FIG. 3, for detecting data corruption between storage systems, in accordance with one embodiment of the present invention. FIG. 6 is intended to provide an illustration of one implementation and is not intended to suggest any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made by one skilled in the art without departing from the scope of the present invention, as recited by the claims.

[0071] In step 602, component 122 generates a secure symmetric key. In various embodiments of the invention, component 122 generates a secure symmetric key between a source and a target system using QKD, which may be used for in-flight data replication. For example, storage system 111 (the source system) receives an instruction to send data to storage system 121 (the target system). In this example, component 122 generates a secure symmetric key between storage system 111 and storage system 121 to secure the data transaction between storage system 111 and storage system 121. In various embodiments of the invention, component 122 discovers the physical location of a storage instance in a cloud (e.g., cloud 170 and / or cloud 172), collects information from underlying received quantum keys (e.g., quantum key 116 and quantum key 118), and uses the collected quantum keys to store, maintain, and encrypt data.

[0072] At step 604, component 122 encrypts one or more packet payloads. In various embodiments of the invention, component 122 encrypts one or more packet payloads within Ethernet packet frames, keeping routing intact for efficient path traversal of block data across clouds 170 and 172. Component 122 may calculate a checksum of the data payload for an Internet Protocol (IP) packet and request submission to a blockchain ledger (e.g., blockchain 144) along with the IP packet ser_no and checksum. In various embodiments of the invention, component 122 stores the checksum data as a payload on blockchain 144 via ledger state database 142, and the stored checksum can be requested by a target system.

[0073] In step 606, component 122 performs information tunneling for data transfer between storage systems. In various embodiments of the present invention, component 122 may perform information tunneling using the enabled communications described above, as appropriate, for data transfer between storage system 111 and storage system 121. In various embodiments of the present invention, component 122 provides an inbound or out-of-bound API infrastructure for communication between QKD devices (e.g., quantum device 103 and quantum device 104) and block storage instances in the cloud based on physical device identification.

[0074] In step 608, component 122 determines whether the checksum data matches the IP packet extracted checksum and the blockchain-based checksum. In various embodiments of the present invention, component 122 uses quantum key transport mode encrypted packets to transmit data to a target location via a cloud infrastructure network (e.g., replication link 115). Component 122 determines whether the checksum data matches the stored IP packet extracted checksum and the blockchain-based checksum by comparing the checksum data at the target system with the IP packet extracted checksum and the blockchain-based checksum. If component 122 determines that the checksum data matches the IP packet extracted checksum and the blockchain-based checksum (yes step), component 122 proceeds to step 616. However, if component 122 determines that the checksum data does not match the IP packet extracted checksum and the blockchain-based checksum (no step), component 122 proceeds to step 610. In various embodiments of the present invention, if component 122 determines that the checksum data does not match the IP packet extracted checksum and the blockchain-based checksum, component 122 issues the data SEND_FAILURE and a retransmission is initiated because the original data is corrupted.

[0075] Component 122 decrypts the data payload in step 610. In various embodiments of the invention, if the checksums match, component 122 decrypts the data payload.

[0076] Component 122 processes the decrypted data in step 612. In various embodiments of the invention, component 122 processes the decrypted data payload.

[0077] In step 614, component 122 identifies corruption in the data payload. In various embodiments of the present invention, component 122 detects and identifies the level of corruption in the data payload based on the comparison outlined in step 608, and updates each entity of the detected and identified data accordingly.

[0078] In step 616, component 122 verifies the identified corruption. In various embodiments of the invention, component 122 verifies the blockchain payload for corruption if frequent checksum mismatches trigger a security breach quarantine requiring corrective action. The frequent checksum mismatch trigger can be a predetermined or customizable number. In various embodiments of the invention, component 122 selects a blockchain-enabled payload validation for a symmetric QKD encryption mechanism deployed as a service model. In various embodiments of the invention, component 122 enables secure replication via cloud 170 and / or cloud 172 to enable configuration analysis.

[0079] Component 122 updates each entity of the detected and identified data at step 618. In various embodiments of the invention, component 122 updates each entity of the detected and identified data.
