A New Random Encryption Algorithm for Character Type Cipher

Abstract

Character type cipher is always used in web application system and can be deciphered by the illegal users through "run dictionary", so, a new random encryption algorithm for character type cipher is put forward in this paper. The encryption parameters are randomly generated in the algorithm, and random confusion is adopted in the cipher text structure, so the same plaintext can produce different ciphertexts.the experimentation shows that the algorithm is feasibility and validity.
