Method for generating key stream for encryption
A recently granted patent (Publication Number: US11979488B2) discloses a processor-implemented method for generating a key stream. The method involves receiving a message, generating round keys based on various parameters including a secret key and a prime number, and performing modular addition operations to create a key stream for encrypting the message. The process includes multiple rounds of functions, including linear and nonlinear transformations, to generate output vectors and ultimately create the key stream using a combination of round keys. The method aims to enhance encryption techniques by utilizing complex mathematical operations and multiple layers of functions to ensure secure communication.
Furthermore, the patent also describes an apparatus for implementing the method, comprising processors and memory to execute instructions for key stream generation. The apparatus follows a similar process as the method, involving the generation of round keys, performing modular addition operations, and utilizing various functions to create the key stream for encrypting messages. By incorporating both hardware and software components, the apparatus provides a comprehensive solution for secure communication through advanced encryption techniques. Overall, the patent highlights a sophisticated approach to key stream generation, emphasizing the importance of robust encryption methods in safeguarding sensitive information in digital communication channels.
