基于身份加密的Ad hoc网络安全模式

Ad hoc Network Security Schema of Identity-based Encryption

无线Adhoc网络由一些没有中心管理机构的结点组成,由网络中的所有结点共同担负职责.由于Adhoc网络比传统的无线网络更加容易受到攻击,提出两个有效的安全模式用于Adhoc网络,结点通过使用非交互性计算对称密钥,减少通讯开销,并允许结点为不同的组生成它们的广播密钥,提出一种无碰撞方法计算这些密钥,最后介绍一种基于对称密钥体制的认证广播模式和相应的数字签名模式.

Wireless ad hoc networks consist of nodes with no central administration and rely on the participating nodes to share network responsibilities. Such networks are more vulnerable to security attacks than conventional wireless networks. This paper presents two efficient security schemes for these networks that use pairwise symmetric keys computed non - interactively by the nodes which reduces communication overhead. Nodes are allowed to generate their broadcast keys for different groups and propose a collisionfree method for computing such keys. The paper also introduces an authenticated broadcast scheme based on symmetric keys and a corresponding signature scheme.
