TLS在无线环境下的改进及安全性分析

Improvement of TLS in the Wireless Environment and its Security Analysis

在有线的公钥基础设施 PKI(Public Key Infrastructure)中,大多数都是采用 TLS(Transport LayerSecurity)建立安全通道,保证了数据传输的安全性。但在无线领域中,TLS 的某些特点不能适应无线应用环境,因此本文针对无线终端以及协议层的不同,重点介绍了无线安全层安全协议 WTLS 中对 TLS 的改进(WirelessTransport Layer Security),并对 WTLS 的安全性进行了简要的分析。

TLS is used to ensure data transport security in most PKIs(Public Key Infrastructure), but some of the characters of the TLS cann’t adapt to the wireless telecommunication environment. This paper puts emphasis on the improvement of the TLS in the wireless security layer protocol-WTLS(Wireless Transport Layer Security) and makes an analysis of its security..
