| 摘 要： | 安全性是WLAN应用的核心问题，IEEE 802.11i定义了WLAN安全基础框架，其中，四次握手协议4-WAY实现会话密钥交换与更新。分析表明4-WAY易遭受拒绝服务攻击，提出了一种改进会话密钥协商协议3-WAY, 分析表明该协议具有更好的消息认证和完整性保护，以及高效性。采用通用可组合安全模型对3-WAY进行分析，证明该协议能够实现密钥交换理想函数，具有通用可组合安全性。该协议具有广泛适用性。

| Abstract: | The security is the core in the applications of WLAN. The 4-WAY handshake protocol realized the key exchange and update in the WLAN security basement framework which was defined by IEEE 802.11i. The analysis showed that the 4-WAY handshake was vulnerable to denial-of-service attack. This paper advanced the modified session key agreement protocol, 3-WAY, which was showed that it provided better information authentication, integrality protection and efficiency. In addition, analyzed the 3-way handshake protocol in the universally composable (UC) security model and proved that this new protocol could realize the key-exchanged ideal function and came to the universally composable security. This new protocol has abroad flexibility. |
