A system, method, and computer product that accelerates encryption and decryption of data while using both a static key and a dynamic key. The present invention eliminates intermediate decryption of data that is transmitted between computer systems. More particularly, encryption efficiency is improved by eliminating decryption of the statically encrypted data while incorporating the advantages of a dynamic key such as enabling rapid change of the dynamic key. The efficiency improvements reduce the computer resources required to protect the data and therefore stronger data encryption may be enabled with the saved computer resources. End-to-end security of the data is maintained without the need for trusted data servers.

A system and method for providing end-to-end security of content over a heterogeneous distribution chain is provided. A content owner provides content to an aggregator that receives the content and processes the content. The processing may involve decrypting the content and associating at least one of a unique fingerprint and a watermark to the decrypted content. The unique fingerprint and a watermark to the decrypted content provide identifying characteristics to the content. Additional content-based fingerprints may be used to monitor quality of consumer experience for Video and Audio. The content may be sent in a decrypted state to a client or in an encrypted state. When the content is encrypted the aggregator wraps and encrypts the content with a signature such that an end-to-end flow of the content may be determined. Application Level encryption is used to provide network/distribution medium transparency as well as persistent encryption. When the content is transmitted from a consumer to another consumer the transmitting consumer loses rights to the content.

A mobile communications network has mobile communications capabilities and supports a secure messaging service, such as an SMS messaging service, that allows a message sender and at least one message receiver (at least one among the message sender and the message receiver being a user of the mobile communications network) to exchange messages encrypted by means of a cryptographic process performed by the message sender, so as to obtain an encrypted message that can be decrypted by a corresponding cryptographic process performed by the intended message receiver. End-to-end security of the exchanged message is thus achieved. A cryptographic algorithm, exploited by the user of the mobile communications network for performing the cryptographic process, is modified by exploiting the mobile communications capabilities of the mobile communications network. Robustness and reliability over time of the end-to-end security messaging is improved.

Clients that are connected on a private network and which are assigned a private IP address that is not routable on the Internet can connect to the Internet through a router/server that includes a network address translator (NAT). For outgoing packets, the NAT translates the client's private source IP address and generalized port number (GPN) to the NAT's global IP address and GPN. For incoming packets sent to the NAT's global IP address and GPN, the NAT translates the global destination IP address and GPN to the client's private IP address and GPN. For protocols which cannot be directly supported by the NAT, such as those in the IPSec security protocol suite, the NAT is extended by creating in the NAT's translation table an entry that associates, for a specific unsupported protocol, a client's private IP address and GPN, the NAT's global IP address and GPN, and a foreign address on the Internet, that is valid until a specified or default expiration time. Outgoing packets from the client to that foreign address and incoming packets from that foreign address to the NAT's global IP address and GPN are translated according to the entry until the entry expires. In associations with these translations to outgoing and incoming packets, the client implements any Application Layer Gateway (ALG) that would otherwise be implemented at the NAT. Further, at the client, outgoing packets are modified before being transmitted so as to pre-compensate for the effects of the translations. Incoming packets at the client from the NAT are similarly modified so as to post-compensate for the effects of the translations. For the IPSec protocol, these modification include adjusting the checksum in the TCP or UDP header to account for IP address and TCP or UDP port number translations.

The invention relates to an end-to-end security assurance method under an IoT (Internet of Things) cloud environment, belonging to the fields of loT and cloud computing. Firstly, a PKI authenticationmechanism based on an ellipse curve algorithm is used to realize the authentication and key negotiation of a gateway and a cloud server, and establish a secure channel between the gateway and the cloud server; then the bidirectional authentication protocol based on the modified symmetric key is used to realize the authentication and key negotiation of a resource-limited node and the gateway; and finally a session key between the gateway and the cloud server is used to encrypt a session key between the node and the gateway, and the encrypted session key is sent to the cloud server, thus completing the establishment of the secure channel between the terminal node and the cloud server. The invention guarantees the identity validity of the node and the cloud server, and meanwhile, effectivelyreduces the computing cost of the sensor node. The authentication of the cloud server is indirectly realized by the gateway, thus reducing the authentication times between the gateway and the cloud server, and realizing the secure communication between the terminal node and the cloud server.

To address the security requirements for cyber-physical systems, embodiments of the present invention include a resilient end-to-end message protection framework, termed Resilient End-to End Message Protection or REMP, exploiting the notion of the long-term key that is given on per node basis. This long term key is assigned during the node authentication phase and is subsequently used to derive encryption keys from a random number per-message sent. Compared with conventional schemes, REMP improves privacy, message authentication, and key exposure, and without compromising scalability and end-to-end security. The tradeoff is a slight increase in computation time for message decryption and message authentication.

This invention concerns the implementation of end-to-end security for the communication between objects in the domain of the Internet of Things (or Internet of Objects). The purpose of the patent is dealing with the setup of secure authorized information channel between data source (M2M device) and data consumers (consumer entity). According to the present invention, the access to a M2M device by a consumer entity (consumer application) is controlled by a M2M authorization server. The M2M authorization server is the entity in charge of managing access rights for the M2M device and makes the decision regarding the access to the resource by the consumer entity (consumer application). The M2M server is an entity that enforces the decision and enables the access to the M2M device. When a consumer application needs to communicate with a M2M device, the present invention proposes a method for authorizing a consumer application to access a M2M device and for encrypting the communication between the consumer application and the M2M device. The M2M authorization server computes security credentials which are sent to the consumer application.

The present invention includes one or more clients in communication with a server. The client desires to send a storage construct to the server for storage. The client negotiates a transmission key with the server. The client generates a storage key associated specifically with the storage construct. The client encrypts the storage construct using the storage key and encrypts the storage key using the transmission key. The encrypted storage construct and encrypted storage key are sent to the server. The server decrypts the storage key using the transmission key. The server stores the storage construct on a storage device separate from a storage device storing the storage key. Preferably, any changes to the storage construct location, the storage key location, or the storage construct name are tracked and proper modifications are made to an association relating the location of the storage construct and the location for the corresponding storage key.

End-to-end security is established automatically for network communications. In one embodiment a first host is associated with a policy manager that determines, for the first host, whether a secure session is permissible. If the secure session is determined to be permissible then the policy manager signals to intermediate devices in order to prompt establishment of SA/DA pinholes. In an alternative embodiment a neutral policy broker determines, for both first and second hosts, whether the secure session is permissible and signals to the intermediate devices to establish the pinholes if the secure session is permissible. In another embodiment the end-to-end session includes back-to-back tunnel mode sessions linked by at least one intermediate device. The intermediate device is operative to decrypt and re-encrypt traffic in the session, and may be configured by a policy manager or policy broker. Further, another security association can be nested in one or more segments of the session in a manner that permits one host to access a third host or secure resource which is shielded from the second host.
