摘　　要：SSL VPN是解决远程用户访问敏感数据最简单、最安全的一种技术,具有高易用性、低管理、低成本等优点。但是SSL VPN作为一种新的安全技术,还存在响应速度慢的问题。分析了SSL VPN响应速度慢的原因,提出了采用ECC算法代替RSA算法和按需分级加密的方法。实验结果表明,在保证数据安全性的基础上,该方法加快了系统的响应速度,并且提高了系统性能。SSL VPN is the simplest and most secure kind of technology for solution of remote user access to sensitive data with the characteristics of ease use, low management and low cost. But as a new SSL VPN secu- rity technology, there are still problems of slow response. The reasons for the slow response of SSL VPN are analyzed and a new method of grade encryption is proposed instead of using the ECC algorithm to replace RSA algorithm. Experimental results show that the new method accelerates the speed of response of the system and improves the system performance based on the data security.
