A novel cryptosystem based on grey system theory and genetic algorithm

In this paper, we first attempt to introduce the biological concepts of genetic factor and genetic variation into the study of a Kaleidoscope-Queer (in brief, K-Q) cryptosystem. The novel K-Q cryptosystem including the genetic factor, (GM, X,;,(x)), call be applied to ensure the security of an information system. The main contributions include the K-Q cryptosystem concept with genetic factor, the existence theorem of alpha-era K-Q cryptosystem with genetic factor, the limited embedded theorem of K-Q cryptosystem with genetic factor, and the genetic variability theorem of K-Q cryptosystem.
