基于双线性对的Ad hoc网络主动秘密共享方案

针对现有的基于双线性对的安全机制都假设在整个Ad hoc网络生存期内系统都是安全的,而基于该假设的Ad hoc网络并不安全的问题。重新定义了Ad hoc网络的攻击者模型,对传统的主动秘密共享方案进行了扩充,提出了基于双线性对的Ad hoc网络主动秘密共享方案,周期性地更新系统私钥的影子和网络节点的私钥,以提高网络安全机制的安全性和鲁棒性,并对其安全性和鲁棒性进行证明。结论表明,基于双线性对的密码体制非常适合建立实用的、轻量级的Ad hoc网络的安全机制。

Proactive secret sharing scheme for Ad hoc networks based on bilinear pairing

The existing secure solutions of bilinear pairing are based on the assumption that Ad hoc networks are secure during the whole lifetime.In fact this assumption is not true,and this results in insecure Ad hoc networks.A new attacker model of the Ad hoc network is presented,and a proactive secret sharing scheme with bilinear pairing for Ad hoc networks is proposed.The proposed scheme,extending traditional proactive secret sharing scheme,periodically refreshes the shares of the master key and secret key of nodes.To enhance the security and robustness of security mechanism for Ad hoc network systems and verifies the security and robustness.This conclusion shows that public-key cryptography based on bilinear pairing is a practical,lightweight secure solution suitable for Ad hoc networks.
