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.
