摘要

在传感器网络中

Sybil攻击是一类主要的攻击手段。通过随机秘密信息预分配

利用节点身份证人确认机制

提出了防御传感器网络Sybil攻击的新方案并进行了综合性能分析。在新方案中

基于单向累加器建立了传感器网络节点秘密信息管理和分配方案

在共享密钥建立阶段

提出了传感器网络认证对称密钥建立协议

并在universally composable(UC)安全模型中对该协议进行了可证明安全分析

该协议可建立网络邻居节点之间惟一的对称密钥。

Abstract

A particularly harmful attack against many sensor network applications is known as the Sybil attack.A novel approach which is sensor node identity witness information validation for random secret information predistribution to defend against the Sybil attack was proposed

and their comprehensive performance was analyzed.In random secret in-formation predistribution

new secret information assignment schemes were proposed and assign a random set of key-related information to each sensor node based on one-way accumulators.In the common keys set-up phase

node-to-node identity witness authentication and key exchange protocols（IDW-AKE）which are provably secure against the active adversaries in universally composable model was proposed.Using IDW-AKE protocols

each node can com-pute the unique common keys it shares with its neighbors.
