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.

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. A binary tree of sums is computed to provide range information and size reduction for the device health vector, and a reduced integer vector representation of the binary tree of sums is generated. The reduced integer vector is encoded as binary data based on a universal integer code and a recursive integer encoding. Additional diagnostic information, also represented as integer vectors, is added by appending sub-trees to the binary tree of sums and encoding each sub-tree with the same universal integer code and recursive integer encoding. This encoding method provides an efficient encoding yielding minimum data size while maintaining backward compatibility with many currently deployed decoders and verifiers.

In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and / or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.
