Abstract

This study applies the grey data generating techniques in grey system theory on a novel cryptosystem, which is guiding a new research in the field of information security. In this paper, we present the concepts of sum-lock, difference-lock, sum-ladder, and difference-ladder. Using these concepts, we can obtain a cryptosystem with lock generation and sum-difference mixed ladder. The cryptographic algorithms for our cryptosystem are also presented and an illustrative example is used to verify it.
