A New Approach for Data Cryptography

Due to the large number of different computer applications transactions on the internet, cryptography is a vital key in ensuring the security of the transactions. Cryptography is an important way of achieving data confidentiality, data integrity, user authentication and non-repudiation. In this paper we will introduce a new approach of message encryption-decryption, this approach will be implemented, and the experimental results will compared with the results of DES method of data cryptography. The following features of the proposed approach will be proved:-Simplicity, Efficiency, High security level, Flexibility.
