一种支持不诚信行为发现的双线性映射密钥管理方案

Bilinear Map Key Management Scheme with Dishonest Behavior Discovery

针对大规模移动Ad Hoc网络中存在的不诚信行为问题,基于组合公钥技术和门限密码体制的结合,并引入双线性映射算法设计秘密分片验证机制,提出一种新的支持不诚信行为发现的移动Ad Hoc网络密钥管理方案.通过与已有的密钥管理方案相比较,本方案在保证效率、安全和扩展性要求的前提下,具有较强的健壮性,能够适用于大规模移动Ad Hoc网络.

In large-scale mobile Ad-Hoc network, there exists problem of nodes＇ dishonest behaviors. Due to this, we designed a novel key management scheme with dishonest behavior discovery mechanism. The proposed scheme is based on techniques of combined public key and threshold secret sharing, and uses bilinear map algorithm to design the verification mechanism of secret shares. Comparisons with existing schemes show that the proposed scheme not only ensures good efficiency, security and scalability, but has strong robustness against dishonest nodes. The proposed scheme can suit large-scale mobile Ad-Hoc network well.
