一种基于SOCKS5的Web安全代理技术

The Research on the Technique of Web Security Proxy Based on SOCKS 5

综合公钥密码算法(RSA)和数据加密标准(DES)的优势,用DES方法加密待传送的Web数据,使用RSA方法对DES密钥进行加密,提出一种基于SOCKS 5的,RSA和DES相结合的Web安全代理方案.通过性能测试和安全性分析表明,使用RSA传递DES密钥可保证DES每次加密都使用新的密钥,杜绝黑客通过分析明文/密文获得密钥,从而能防御网络数据包被恶意截取后造成泄密,安全代理既保证Web数据的加密速度,又保证DES密钥的安全性和可管理性.

Synthesizing the advantages of rivest shamir adelman （RSA） and data encryption standard （DES）. Using the method of DES to transmit the encrypt Web data and using RSA to encrypt the encryption key of DES. A Web security proxyscheme combined RSA ; DES method based on SOCKS 5 was proposed. The performance test and security analysis show that RSA could guarantee a new encryption key used in each DES encryption, and prevent the hacker to get the encryption key by analysis of plain text and cryptograph. Therefore, the scheme ensured that the secrecy would not be lost even the net data package had been intercepted by hackers. The Web security proxy also ensured the encryption speed, as well as the security and administration of encryption key.
