Authentication mechanism and improvement of IEEE 802.1x protocol
IEEE 802.1x协议的认证机制及其改进

Based on the analysis of the IEEE 802.1x authentication mechanism, to fetch up the flaws that IEEE 802.1x lacks source authenticity and integrity protection, an improved IEEE 802.1x authentication mechanism (AIP) was proposed. By adding a Protection part into EAPOL packets, this scheme can fetch up the flaws of IEEE 802.1x, such as intermediary attack and session hijack. Through the capability analysis, the scheme has more advantages as source authenticity and integrity protection than the original one.
