A system and method of performing communications over a communications network that uses a communication protocol having multiple different versions, provides for backwards compatibility when devices that support a higher or more secure version of the communication protocol are added to a network having devices that only support a lower or less secure version of the communication protocol. The system and method includes a technique of negotiating and establishing security procedures to be implemented in a communication connection between two devices on the network based on initial session request messages that indicate the version of the communication protocol supported by one or both of the devices. This system and method enable higher and lower protocol version devices (i.e., devices that conform to or that use the same communication protocol but that have different versions of the protocol installed therein) to communicate with one another in the most secure manner, thereby making higher version devices added to a network backward compatible with lower version devices already within the network.

Compressing and re-securing blockchain data using a large codeword model (LCM) with deep learning. The LCM tokenizes the blockchain into sourceblocks, assigns unique codewords to each sourceblock, and processes the codewords through a deep learning core, enabling efficient compression, semantic understanding, and generation of blockchain data. In the event of a compromised block, the system re-encodes and rehashes the entire compressed chain, generating a new secured chain while preserving the original chain as metadata for backward compatibility. The LCM-based approach enhances security, efficiency, and resilience of blockchain networks, offering significant advantages over existing techniques.

The invention discloses a data processing method based on a custom message model and related equipment thereof, and belongs to the technical field of big data. Firstly, a client defines a data transmission object and selects a proper data transmission format; then, the client performs structured assembly of the AP I request by using a preset self-defined message model to form a standard-format AP I request, and sends the standard-format AP I request to a back-end server; then, the back-end server receives an AP I request, analyzes the request by using a user-defined message model, and extracts a data transmission object; and then, the back-end server processes the field to be processed. And then, the back-end server serializes the processing result according to the response volume data structure to form a serialized object, and returns the serialized object to the client through the AP I gateway. And the client receives the serialization object sent by the rear end, deserializes the serialization object, and finally obtains a data processing result. According to the invention, the processing performance of the AP I request and response is improved, and the expansibility and backward compatibility of the interface are enhanced.

Method and apparatus for encoding device health information for use in remote health attestation where the device health is represented by an integer vector with a zero-value representing a healthy condition and a non-zero value representing an unhealthy condition.
