无线局域网的认证机制是网络安全比较重要的保证,其中EAP协议在局域网中比较通用,它的TLS类型有比较高的安全性。本文介绍了无线局域环境下的EAP-TLS认证机制,对其原理介绍,分析其安全性,提出了改进的两种方案,但在其性能方面仍有待深入研究。 Wireless LAN authentication mechanism is more important network security assurance, EAP protocol which is more common in the LAN, its TLS type has a relatively high security. This paper introduces the EAP-TLS authentication mechanism in wireless local area environment, introduces its principle, analyzes its security, and proposes two improved schemes. However, its performance needs to be further studied.
