Abstract: | In this paper we are introducing a high Performance Symmetric Key Cryptography Schema used to increase the performance of symmetric key encryption algorithms like DES increasing their security by using compression and splitting techniques and other enhancement points. In this schema, the performance enchased by dividing data of into smaller equal parts. Then each parts is subjected to compressed & then using DES algorithm for encryption. The enhancement points in this paper is that we use the CRC (cyclic redundancy checksum) for data transmission The CRC method treats the message as a polynomial The data transmitted (the code vector) is the original m-bit message followed by the r bit checksum. If attacker or hacker wants to change the data, Receiver computes the checksum from the first m bits of the received data, and verifies that it agrees with the last r received bits. An analysis and results of this schema and comparison of this scheme performance with another existing schema is presented in this paper. |
