网络中基于单向函数密钥链的广播认证协议

Survey of broadcast authentication protocols based on one-way key chain in sensor networks

无线传感器网络中的广播认证技术能够保护广播报文不被恶意篡改或伪造,对于战场侦察、森林火险监测等应用具有重要的意义。现有的广播认证协议中基于单向函数密钥链的协议以较高的认证效率得到了研究工作者的普遍认可,对现有的这些认证协议进行了介绍和分析,并提出了可能的进一步研究方向。

Authentication of broadcast messages in sensor networks was a very important mechanism to ensure that data from a valid source was not altered in transmits, especially for applications such as battlefield surveillance and forest fire detection. In all broadcast authentication protecols, protocols based on one-way key chain were more efficient and accepted by researchers. A survey about those protocols was given and a probable future work was pointed out.
