Currently, network built with C/S model has been widely used in E-commerce, ERP and corporate intranets. Therefore, the security of network transmission in this model has become an increasingly important issue. In view of the low security of traditional DES algorithm and slow RSA encryption speed, this paper presented an Encryption Algorithms model of data packets on the basis of analyzing the methods of existing network transmission. The algorithm model realizes a simple Authentication Center which simulates Kerberos authentication service. Through improving Kerberos protocol, strengthening the secure of the authentication process and defending the attack of replay effectively, security Transmission by Network of C/S model is realized. The result of experimentation shows that the proposed algorithm has the advantages of fast encryption (decryption) speed, high efficiency, strong safety. Furthermore; it can guarantee integrity in network transmission.
