Description

Technical Field

[0001] The embodiments of the present invention relate to the field of network address allocation technology, and in particular to a method, apparatus, device and storage medium for processing network addresses based on blockchain. Background Technology

[0002] Existing network address (e.g., IPv6 address) allocation systems rely on centralized servers or routers, posing a single point of failure risk, and the address allocation process lacks transparency and traceability. Centralized DHCPv6 server management is common in network address allocation. The server maintains the address pool, receives address requests from clients, and allocates addresses according to preset rules. As the network expands and the number of connected devices increases, the number of requests the server needs to handle increases significantly, easily leading to performance bottlenecks. Moreover, because all address allocation information is centrally stored on the server, if the server is attacked (e.g., by DDoS attacks) or experiences hardware failures or software errors, the address allocation service of the entire network will be severely affected, even leading to service interruption. Summary of the Invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0027] Disadvantages of existing technology:

[0028] (1) High risk of single point of failure: Once a centralized DHCPv6 server fails, such as due to hardware damage or malicious attack, the IPv6 address allocation service of the entire network will not be able to operate normally, resulting in new devices being unable to obtain addresses and the network connection of connected devices may also be interrupted, seriously affecting the stability and availability of the network.

[0029] (2) Poor scalability: As the network scale continues to expand, the number of access devices increases dramatically, and the number of address requests that centralized servers need to handle rises significantly. The server's processing and storage capabilities are limited, and under high concurrency, response delays are likely to occur, making it impossible to meet the address allocation efficiency requirements of large-scale networks.

[0030] (3) Lack of transparency and traceability: The existing address allocation process is controlled by a centralized institution. Users cannot verify the legality of the address allocation, nor can they trace the historical allocation records of the address, which can easily lead to address abuse or conflict.

[0031] (4) Insufficient security: In a centralized management model, the server stores a large amount of device address allocation information. Once this information is leaked, it may lead to network security problems, such as address conflicts and malicious device access. At the same time, centralized servers are more likely to become targets of hacker attacks. After hackers obtain the server's address allocation information, they may tamper with the address allocation records, leading to network paralysis or security vulnerabilities. Its security is difficult to guarantee.

[0032] (5) Inefficiency: In large-scale IoT scenarios, centralized address allocation systems may not be able to efficiently handle address requests from a massive number of devices, leading to increased latency and wasted resources.

[0033] Figure 1 This is a structural diagram of a blockchain-based network address processing system according to an embodiment of the present invention, as shown below. Figure 1 As shown, the system comprises a blockchain network, a client, smart contracts, and an address pool management module. The blockchain network, consisting of multiple blockchain nodes connected via a P2P network, is responsible for storing and verifying address allocation information. The client is installed on devices that need to obtain network addresses (e.g., IPv6 addresses), and is responsible for collecting device information and interacting with the blockchain network. The smart contracts are deployed on the blockchain, implementing the specific logic and rules for network address processing. The address pool management module is responsible for maintaining the network address pool and managing and allocating addresses within it.

[0034] For blockchain networks, blockchain nodes include the following types: Full nodes: Store the complete blockchain ledger, participate in the consensus mechanism, and verify and record transactions (address allocation, updates, releases, etc.); Full nodes ensure the integrity and consistency of the entire blockchain network by continuously synchronizing and verifying blockchain data. Light nodes: Store only partial blockchain information, such as block headers, and verify the validity of transactions by communicating with full nodes; Light nodes are suitable for resource-constrained devices and can reduce the consumption of storage and computing resources.

[0035] The consensus mechanism in blockchain networks employs Proof-of-Stake (PoS), where nodes participate in record-keeping and transaction verification based on their stake (such as the number of tokens they hold or their contribution to the system). In the address allocation system, a node's stake can be determined based on factors such as the computing and storage resources it provides, or its contribution to the system's stability. The PoS mechanism can improve the performance and efficiency of blockchain networks while reducing energy consumption.

[0036] Each node stores a complete blockchain ledger, which consists of multiple blocks. Each block contains a certain number of address allocation records. The blocks are linked together by hash values ​​to form an immutable chain structure. The address allocation records include information such as device identifier, allocated IPv6 address, allocation time, device type, and network environment information.

[0037] Figure 2 This is a flowchart illustrating a blockchain-based network address processing method provided in an embodiment of the present invention. This embodiment is applicable to situations involving the allocation and updating of network addresses. The method can be executed by a blockchain-based network address processing device, which can be implemented in software and / or hardware, optionally through an electronic device such as a mobile terminal, PC, or server. Figure 1 As shown, the method specifically includes the following steps:

[0038] S110, the blockchain node receives a network address processing request sent by the client.

[0039] The network address processing request includes a network address allocation request or a network address update request. Both network address allocation and update requests include device identifier, device type, network environment information, and request time; the network address update request also includes the first current network address. The network address can be an IPv6 address.

[0040] In this embodiment, when a device starts up or connects to the network, the client collects the device's unique identifier (such as MAC address), device type (such as computer, server, IoT device, etc.), and network environment information (such as subnet and network mask). Based on the collected information, the client generates a network address allocation request with the format {device identifier, device type, network environment information, request time}, and sends the network address allocation request to any node in the blockchain network.

[0041] In this embodiment, when a device needs to update its network address, the client sends a network address update request to the blockchain node, which includes the first current network address, device identifier, device type, network environment information, and request time.

[0042] Network address processing requests are encrypted to ensure information security. Symmetric encryption algorithms (such as AES) or asymmetric encryption algorithms (such as RSA) can be used to encrypt the requests. The client sends the generated network address processing request to any node in the blockchain network. Communication can be conducted via UDP or TCP protocols to ensure reliable transmission of the request.

[0043] Access to nodes and smart contracts in the blockchain network is strictly controlled, allowing only authorized nodes and users to perform operations such as address allocation, updating, and release. A role-based access control (RBAC) model is employed, assigning different operational permissions based on the user's role and privileges.

[0044] S120 uses smart contracts to verify network address processing requests.

[0045] In this embodiment, the network address processing request is verified using a smart contract, including at least one of the following: verifying whether the device identifier format is valid; or verifying whether the device type is in a preset list of valid types; or verifying whether the request time is within a valid time range (to prevent expired or malicious requests); or verifying whether the first current network address is valid based on historical address processing records. For example, verifying whether the MAC address conforms to a standard hexadecimal format and whether the device type is in a preset list of valid types.

[0046] S130, if the verification passes, select the target network address from the network address pool.

[0047] Specifically, the method for selecting a target network address from the network address pool can be based on any of the following algorithms: random selection algorithm, sequential selection algorithm, or load balancing algorithm.

[0048] One method for selecting a target network address from the network address pool based on a random selection algorithm is to randomly select an available network address from the pool for allocation. This algorithm is simple and efficient, and suitable for situations where there are sufficient addresses in the initial address allocation phase. Another method is to select an available address from the network address pool sequentially according to the address order in the pool. This algorithm ensures the orderly allocation of addresses and is suitable for local address selection after block partitioning. A third method is to select a target network address from the network address pool based on a load balancing algorithm. This algorithm selects an available address from a less loaded address segment based on the usage of each subnet or address segment in the network. This algorithm improves the utilization of network resources and avoids overuse of local address segments.

[0049] S140, the target network address is sent to the client so that the client can configure the network according to the target network address.

[0050] After receiving the target network address returned by the blockchain network, the client configures the device's network according to the assigned target network address and related configuration information, enabling the device to access the network normally.

[0051] S150 generates an address processing record based on the target network address and broadcasts the address processing record to other nodes in the blockchain.

[0052] In this embodiment, the method for generating an address processing record based on the target network address can be associating the target network address with a device identifier to generate an address processing record. The record includes the device identifier, the allocated IPv6 address, the allocation time, the device type, network environment information, and other information.

[0053] In this embodiment, the generated address processing records are added to the blockchain, and the consistency and immutability of the records are ensured through a consensus mechanism. Specifically, the address processing records are packaged into a transaction and broadcast to the blockchain network for verification and accounting by nodes. When storing address processing records, sensitive information such as device identifiers is anonymized. A hash algorithm is used to hash the device identifier, and only the hash value is stored to protect device privacy.

[0054] Optionally, after broadcasting the address processing record to other nodes in the blockchain, the following steps are also included: if the network address processing request is a network address allocation request, then the state information of the target network address is adjusted to the allocated state; if the network address processing request is a network address update request, then the state information of the first current network address is adjusted to the released state and the state information of the target network address is adjusted to the allocated state.

[0055] The status of a network address includes available status, allocated status, and released status.

[0056] Optionally, the solution in this embodiment further includes the following steps: receiving a network address release request sent by the client; verifying the network address release request using a smart contract; and if the verification passes, adjusting the status information of the second current network address to the released state.

[0057] The network address release request includes a second current network address. The network address release request can be verified using a smart contract by: verifying the legitimacy of the second current network address and whether its current state is allocated; if the second current network address is legitimate and its current state is allocated, the verification passes. After adjusting the state information of the second current network address to a released state, the processing record associated with that address is deleted from the blockchain (the record can also be retained for traceability).

[0058] Based on the above embodiments, the following is the process of address allocation, address update, and address release:

[0059] The address allocation process includes the following steps: (1) The device accesses the network, and the address allocation client collects device information and generates an address request; (2) The client sends the address request to a node in the blockchain network; (3) After receiving the request, the node broadcasts it to the entire blockchain network; (4) After receiving the request, the smart contract performs a legality verification; (5) After the verification is successful, the smart contract obtains an available IPv6 address from the address pool management module; (6) The smart contract generates an address allocation record and adds the record to the blockchain; (7) The smart contract returns the allocation result to the node in the blockchain network; (8) The node forwards the allocation result to the address allocation client; (9) After receiving the allocation result, the client configures the device's network and completes the address allocation.

[0060] The address update process includes the following steps: (1) The device needs to update its IPv6 address, and the address allocation client generates an address update request; (2) The client sends the update request to a node in the blockchain network; (3) The node broadcasts the request to the entire blockchain network; (4) After receiving the request, the smart contract verifies the legality of the device's current address; (5) After successful verification, the smart contract obtains a new IPv6 address from the address pool management module; (6) The smart contract updates the address allocation record on the blockchain; (7) The smart contract returns the update result to the node in the blockchain network; (8) The node forwards the update result to the address allocation client; (9) After receiving the update result, the client reconfigures the device's network and completes the address update.

[0061] The address allocation process includes the following steps: (1) When the device no longer needs the currently allocated IPv6 address, the address allocation client generates an address release request; (2) The client sends the release request to a node in the blockchain network; (3) The node broadcasts the request to the entire blockchain network; (4) After receiving the request, the smart contract verifies the legality and status of the address; (5) After successful verification, the smart contract marks the address as released and updates the record on the blockchain; (6) The smart contract returns the release result to the node in the blockchain network; (7) The node forwards the release result to the address allocation client to complete the address release.

[0062] This embodiment solves the following technical problems: (1) Decentralized address allocation: Decentralized IPv6 address allocation is achieved through blockchain technology, eliminating single points of failure and improving system reliability and fault tolerance. (2) Transparency and traceability: The immutability and transparency of blockchain ensure the openness and transparency of the address allocation process and support the traceability of address allocation history. (3) Enhanced security: Malicious attacks (such as DDoS attacks, address hijacking, etc.) are prevented during the address allocation process through the encryption and consensus mechanism of blockchain, ensuring the security of address allocation. (4) Efficient address management: The address allocation process is automated and optimized through smart contracts, supporting address requests from a large number of devices and improving address allocation efficiency.

[0063] In this embodiment, the blockchain node receives a network address processing request from a client. This request includes either a network address allocation request or a network address update request. A smart contract is used to verify the request. If the verification passes, a target network address is selected from the network address pool. The target network address is then sent to the client, enabling the client to configure its network accordingly. An address processing record is generated based on the target network address and broadcast to other nodes in the blockchain. This blockchain-based network address processing method, utilizing blockchain technology to allocate and update client network addresses, improves both security and efficiency.
