可证明安全的基于802.11i的漫游认证协议

An 802.11i Robust Security Network Authentication Protocol of Roaming

随着802.11无线局域网的发展,漫游已经成为它的重要场景.身份认证是保证网络安全的重要措施之一,802.11WLAN中现有的认证协议不能有效地支持漫游.作者提出的基于DH交换的认证协议,不仅满足了漫游对认证协议的特殊要求身份保护和认证时延,而且具有可证明的安全性和必需的安全性质.

With the development of 802.11 wireless local area network（WLAN）, roaming has become an important scenario. Based on DH exchange, an authentication protocol is proposed.This protocol not only guarantees the confidentiality of user＇s identity and decreases the roundtrips of the authentication message but also provides provably security and necessary security attributes. As a result the protocol conforms to the requirements for performance and security in roaming scenario of WLAN.
