Abstract

This article is considered a new encryption. through:

  1. Using the modified encoding ASCII+(ASCII coding), that has additional symbol (the number of characters’ n =257). We will get keys to encrypt it's number (n) instead of (32778) if n=255.
  2. Using the special function  such thatis the symmetric product with modulo of  the numberand    To encrypt the whole  message  simultaneously,   making it difficult to break which  preserve the security information  within the sent  texts and messages.
  3. Find a New Way of encoding ASCII characters to binary system that is more flexible in dealing with long messages and more appropriate to program.

 Keywords: Cryptology Affine, Cryptology RSA, ASCII system, Plaintext, Cipher text, symmetric product with modulo n.
