基于身份的Ad hoc网络密钥管理方案

在具有初始信任的系统模型下，结合可验证秘密共享技术和盲短签名，为Adhoc网络提出了一种基于身份的分布式密钥管理方案。可验证秘密共享技术有效地防范了节点的不诚实行为；利用盲短签名实现了私钥份额在公开信道的安全传输，并减小了计算量和通信量。方案提供了节点双向身份认证功能。和现有Adhoc网络密钥管理方案相比，该方案提供了更高的安全性和运行效率。

Identity -based Key Management Scheme for Ad Hoc Networks

A new identity -based distributed key management scheme using verifiable secret sharing technology and blind short signatures is proposed in the system model with initial trust. The verifiable secret share technology effectively prevents the node from behaving dishonestly. The blind short signature assures the private key share can be transmitted in an unsecure channel. The scheme provides node mutual authentication. The analysis shows that the proposed scheme not only provides greater security, but also improves the efficiency than previous scheme for ad hoc networks.
