摘　　要：通过对WiMAX空中接口阶段认证密钥交换协议的考察,使用椭圆曲线双线性对设计了一个基于ECDLP和ECDH困难性假设的认证密钥协商协议。该协议认证部分是基于身份的认证方案,会话密钥协商部分的运算主要用点乘实现,既提高了协议的安全性又避免了过大的计算开销。与WiMAX空中接口阶段认证密钥交换协议相比,该协议具有更强的安全性和更简单的结构。Through analysis of the framework and security of the original protocols,it is worthwhile to consider how to design a new ID-Based AKA protocol in WiMAX air interface stage.In this design elliptic curve bilinear pairings and the ECDLP and ECDH assumptions are used.The new designed ID-Based AKA protocol＇s anthentication section is an ID-Based scheme and the computing section of key agreement uses elliptic curve operation.This designing method not only prompts security properties of AKA protocol but also avoids additional expensive computational cost.Comparing with the original protocol in the WiMAX air interface stage,the new ID-Based protocol has stronger security and simpler architecture of protocol messages.
