基于优先级策略的TLS握手协议研究

Priority based Policy Research on TLS Handshake Protocol

中文关键词:TLS  session  会话重用

英文关键词:TLS  session  session resuming

中文摘要:

      当大量的用户通过TLS协议访问服务器时，会带来较大的负担，同时浏览器进程关闭时会清除用户所保存下来的session信息，当再次连接时，又需要完整的握手过程。对TLS协议进行分析,在经典握手协议的基础上提出了服务器端session的缓存机制的改进，提高了服务器的缓存利用率；并在客户端实现了运用cookie进行会话重用。结合Java相关技术，对其TLS环境进行配置，并在其上进行了服务器端与客户端的实验，然后对经典TLS握手协议进行效率测试。

英文摘要:

      When a lot of users access the server via TLS protocol, a greater burden is generated, and when the browser is closed, the session information about users will be cleared, and if connected again, it has to complete the full TLS handshake again. The TLS protocol is analyzed based on the classic handshake protocol, and an improved method of caching mechanism of the server side session is designed which improves the server’s cache utilization, and session resume is carried out by cookie in the client side .Combined with Java related technologies, TLS environment is configured, experiments are conducted on server side and client side, and the efficiency of the TLS handshake protocol is tested.
