Abstract

A method is disclosed for establishing a common data encrypting session key (KS) for a cryptographic communication session between two communicating nodes of a data communication system. This is accomplished by requiring KS to be a composite of random data, dynamically generated at each node, i.e., KS=RN1(Image Omitted)RN2, where RN1 and RN2 are random numbers generated at the respective nodes and (Image Omitted) represents modulo 2 addition.
