Chaotic encryption using discrete-time synchronous chaos

We developed a cryptosystem for secure communication between computers using synchronisation of discrete-time chaotic systems. The cryptosystem employs a one-time pad encryption where each message block of M bits is encrypted using a unique set of secret keys that is self-generated within the system. The cryptosystem also features fast encryption rate that only requires a single iteration to encrypt each message block of up to 52 bits. As a result, the cryptosystem is able to generate a ciphertext storage size that is smaller than the inputted information.
