摘要
针对现有的无线传感器广播认证协议在间歇性随机广播数据流中存在的通信开销大的问题,提出基于消息驱动的μTESLA广播认证协议.该协议仅当消息到来时才使用密钥链,无需定时发送参数分发包来更新密钥链,减少了通信开销.针对DOS攻击及网络连通性问题,采用多级密钥链及基于Merkle树的参数包分发机制进一步增强了协议的可靠性.仿真结果表明:在间歇性数据流情况下,协议的通信开销低于Tree-basedμTESLA及MultilevelμTESLA协议.
The existing broad authentication protocol in wireless sensor networks had high communication overhead when the date stream was intermittent and random. To solve this problem, the message-driven μTESLA protocol was present. The key chain was used only when the message occurs, so the communication overhead was decreased. Multilevel key chain and merkle-based parameter distribution scheme were also used to resolve DOS attack and the network connectivity problem. Results show that the communication overhead of this protocol is lower than the tree-based and multilevel μTESLA protocol in the intermittent date streams.
