Abstract :
Proposes a private key cryptosystem in which a specially designed permutation table is used as an enciphering/deciphering key. By the permutation table, an enforced random substitution scheme substitutes the characters in a plaintext message. It is hard to guess the correct plaintext characters from known ciphertext characters. The secure measurement and some possible attacks on the proposed cryptosystem are also discussed
