New method for cryptography using abaoub- shkheam transform

الملخص

Cryptography is very useful in a communication system for authentication and privacy. It affects many activities in our life. In this paper, we developed a new technique for cryptography using Abaoub- Shkheam transforms. Further, we apply the method of iteration for better security In this work, the Abaoub- Shkheam transform has been used as a part of a symmetric key system, by implementing a practical example in encryption and decryption; Abaoub- Shkheam transform has proven its capability to be invested in cryptography and in the data security field in general.
