一個N-D保密方法

Abstract

In this paper, we proposed a new cryptosystem that can transform one plaintext to different ciphertexts nondeterministicly at different times. The propertie sof nondetermination come from the usage of nondeterministic number representa tion(NNR)system. Combined with a deterministic number representation(DNR)syst em, wepropose an N-D cryptoscheme. This cryptoscheme works on the scalar inte gerdomain, that is , both input and output are scalar integers. "One to many" ismost important property of nondetermination, makes the guess of plaintext m oredifficult, hence enforces the security.
