Ad Hoc网络中基于移动Agent的密钥管理及认证

Key Management and Authentication in Wireless Ad Hoc Network based on Mobile Agent

提出了在A d Hoc网络中一种基于移动Agen t的密钥管理及认证方法.移动Agen t在网络中根据一定的运行策略进行移动,并不断地和所经历的节点进行数据交换,在此基础上形成一个节点信息矩阵表,矩阵表中包含了密钥信息.各节点使用其身份作为公钥,主密钥由各节点的私钥分享,从而形成基于身份的门限分布式密钥管理.该方法使用很少的Agen t获得较多的全局信息并快速交换密钥信息,减少了系统的开销,具有很高的效率和鲁棒性.

In this paper, a method of key management and authentication in wireless Ad Hoc network based on mobile agent is introduced. Moving in the network, mobile agents exchange information with the nodes and other agents to build the global information matrix which includes the secret key of nodes according to a policy. Each node uses the identity as its public key. The master private key is shared by the private key of every node. Threshold and identity-based key management and authentication are used. The nodes can exchange the global information and secret key with few agents rapidly. This approach reduces the system overhead and it is very efficient and robust to transfer packets.
