ABSTRACT:
In asymmetric cryptography, initially-set public key and private keys are updated as a function of the chosen prime number pair, a host sending an updated public key exponent and a unique prime-pair key associated with the chosen prime number pair to the client, the client using the unique prime-pair key to look-up and retrieve the chosen prime number pair and determine the updated public key and the updated private key as a function of the retrieved chosen prime number pair, the host and the client encrypting and decrypting exchanged messages with the updated public key and the updated private key without executing another handshake. In one aspect, a large even integer is used by host and client to generate a plurality of prime number pairs, and the unique prime-pair key may be a distance between each prime number of an associated prime number pair.
