ABSTRACT
In this paper we propose a scheme of encryption for Block ciphers in N-alphabet, where every member of any m-block of plain text is enciphered by different permutations which are generated by the help of a secret key word. Further we extend this method to multicode encryption using the fact that encrypting each member differently is the basis of multicode encryption.
KEY WORDS
Encryption, Block cipher, Multicode encryption
