| 摘 要： | 安全性是限制移动Ad Hoc网络广泛应用的主要瓶颈；Ad Hoc网络的安全问题表现为密钥生成、密钥管理和路由安全方面．基于椭圆曲线的密码体制以其更短的密钥长度以及较低的资源需求，更适合应用于资源有限的Ad Hoc环境中、对移动Ad Hoc网络，首先给出基于椭圆曲线密码体制的GDH、3协议产生组密钥的方案；其次利用椭圆曲线密码体制实现安全路由协议SAODV(Securing Ad Hoc on—demand distance vector muting)，并通过试验进一步验证了方案的可行性．

| Abstract: | Security is the bottleneck constrained the application of mobile Ad Hoc networks(MANET),the security includes key agreement key management and secure routing .The Elliptic Curve Cryptosystems (ECC)are proper to be applied in environments like mobile Ad Hoc networks, they can provide equivalent security as the other existing public key schemes,using much shorter keys. A group key agreement method using ECDH (elliptic curve Diffie-Helleman) is presented ,which is based on GDH.3 protocol in MANET, and the elliptic curve digital signature algorithm(ECDSA)) is applied to securing on-demand routing after which was introduced. According to the experimentation results,the feasibility of our scheme is validated. |
