摘　　要：移动自组网具有无中心、自组织、可移动等特点,使得它在战场等特殊场合的应用日渐受到人们的重视,而它的安全问题尤为重要。针对密钥协商的几大安全问题,提出一种新的基于零知识身份认证的密钥协商方案,将零知识证明与椭圆曲线相结合,既实现了隐藏认证节点的私有信息,也实现了需要建立会话的节点间的密钥协商。通过分析证明,本方案依赖椭圆曲线的离散对数问题与双线性对,具有较高的安全性。Nowadays people pay more attention to the using of MANET in special area such as battlefield, because Ad Hoc Network is infrastructure-less, self-organizing and mobile. So the problem of security is very important. Based on the security problems of session key agreement, this paper proposed a new Session key agreement scheme based on anonymous identity authentication. It used zero-knowledge authentication and elliptic curve. This scheme implemented the anonymous identity authentication and Session key agreement between two members who needed to communicate. The results show that the scheme proposed in this paper has high security.
