| Abstract: | The principle of the conventional DES and RSA algorithm is introduced and their characteristics are analyzed. The difference comparison and analysis of the two conventional cryptography algorithms are introduced in many respects, such as the cipher system, algorithms foundation, key distribution, key length, key number, length of plaintext in a block, cipher text length, implement way, cryptography speed, and etc. The attack ways of the two algorithms are provided. And from the view of maintenance the measures to improve the security in the two conventional cryptography algorithms are pointed out for network security people. |
