基于自认证的分簇式MANET网络密钥管理方案

A Clustering Key Management Scheme Based on Self-certified Public Key for Mobile Ad Hoc Network

MANET网是一种不依赖于任何固定基础设施、没有中心控制节点.计算资源受限的新型无线移动网络。本文基于自认证公钥,结合分簇的网络结构提出一种新的适合于Ad Hoc网络的密钥管理方案。新的密钥管理方案不需要公钥证书的存在,有效地降低了用户终端计算、存储能力的需求和系统密钥管理的通信开销。基于分簇的结构将网上节点分成一些相对独立的自治域,既提高了安全服务的可用性和可扩充性,也便于对某些紧急情况快速做出反应。

Mobile Ad Hoc network is a new wireless mobile network does not rely on the assistance of any infrastructure, without the centre control nodes and limited calculation resource. In this paper, based on self-certified cryptography and combined with clustered network structure, we propose a new key management scheme which is suitable to mobile Ad Hoc networks. This new scheme does not need the public key certificates, and effectively reduces the need for calculation and storing capability of the terminals, and decreases the communication overhead in the system secret key management. The clustering structure divides the nodes into relatively independent autonomous domain, which not only enhances the security service availability and scalability, but also eases some of the rapid emergency response.
