| 摘 要： | 针对稀疏Ad Hoc网络的易断易延时特性,采用基于身份的密码体制和椭圆曲线双线性对,提出一种新的稀疏Ad Hoc网络消息签名方案,并对方案的安全性和性能进行了分析。该方案可以解决第三方密钥托管带来的签名伪造问题,限制稀疏Ad Hoc网络中节点私钥泄密带来的伪造消息签名的影响,在保证安全性的前提下,有效减少密钥长度、签名长度与签名的计算量,降低了对网络通信带宽和节点存储、计算能力的要求,符合稀疏Ad Hoc网络的签名需求。

| Abstract: | Aiming at the delay/disruption feature of sparse mobile Ad Hoc network,this paper proposes a novel message signature scheme based on IBC(Identity–Based Cryptography) and ECBP(Elliptic Curve Bilinear Pairings). The security and performance of scheme is also analyzed. This scheme can solve the key escrow problem,limit the invalid message caused by the compromised private keys spreading in the network. On the premise of ensuring security,effective reduction of the key length,signature length and computation,and thus the network communication bandwidth and node memory and computation makes this scheme more suitable for sparse mobile Ad Hoc network. |
