摘要
提出一种轻量级的可扩展的传感器网络广播认证协议,在多级μTESLA中使用了压缩布鲁姆过滤器,取代了由Merkel树实现的对多级μTESLA密钥链进行绑定的过程。该协议具有持续时间长、自愈等属性,通过在每个接收端分配适当的存储空间,极大程度减少了通信负载。并结合类似公钥加密技术(PKC)计算模式的椭圆曲线加密(ECC)算法,实现分析结果表明:该协议可以保证长期的安全性,并能减少能量消耗。
A light-weight and scalable broadcast authentication protocal has been proposed for sensor network. Instead of using Merkel tree to combine multiple μTESLA key chain, it applys compressed Bloom filters to multiple μTESLA. This protocol can support longer duration and prolong the self-healing property. It greatly reduces the communication overhead by allocating moderate space in each receiver. Combing with ECC like PKC computation mode, the result show that this protocol can guarantee long-term security and also reduce energy consumption.
