基于逻辑邻居树的资源受限WSN安全群组管理方案

Resource-limited Secure Group WSN Management Scheme Based on LNT

针对无线传感器网络群组密钥更新过程中通信、计算、存储开销过重以及密钥更新延迟时间过长,重放攻击等安全问题,提出了一种新的资源受限安全群组密钥管理方案,该方案基于逻辑邻居树原理生成多个逻辑群组,每个逻辑群组通过群组控制者维护群组内密钥更新以及管理,无需群组外节点路由支持,同时具有保密性、鲁棒性等特点。分析比较结果表明,新方案通过构建邻居树减少了群组控制者通信、计算、存储方面开销,缩短了群组控制者密钥更新延迟,解决了恶意节点重放攻击等安全问题.

In wireless sensor group, the cost o{ key update process communication, computation and storage in the key update process is excessive, the delay time is too long and also prone to replay attack etc. Conse- quently, a new resource-limited secure group key management scheme is put forward. This scheme is based on logical neighbor tree principle which generates more logical groups, and each logical group maintains the group key update and management by the group controller without the group node routing support,and at the same time, it has characteristics of confidentiality, robustness etc.. Analysis and comparison results show that the new scheme reduces the cost of the communication, computation and storage of the group controller, shortens the key update delay and solves the malicious nodes replay attack issues by implemen- ting INT construction.
