Abstract

Node authentication is an essential security service in mobile ad-hoc networks (MANETs). To provide a node authentication service, we have to construct a distributed certificate authority in MANETs. In this paper, to solve the number of neighbor node problem in fully distributed certificate authority (FDCA) schemes, we propose a distributed certificate authority scheme with weighted secret sharing. Each node's share weight is given with considering current node degree information. Node's share weight has to be adjusted due to the mobility of nodes. We have analyzed our scheme based on security criteria, and have conducted experiments using the ns-2 simulator to evaluate our scheme and compare it with previous schemes. It is shown that the proposed scheme enhances the certificate service stability by adjusting each CA node's secret share weight.
基于加权秘密共享的移动自组织网络分布式证书颁发方案
节点身份验证是移动自组织网络(manet)中必不可少的安全服务。为了提供节点认证服务,我们必须在manet中构建分布式证书颁发机构。为了解决完全分布式证书颁发(FDCA)方案中邻居节点数量的问题,提出了一种加权秘密共享的分布式证书颁发方案。在考虑当前节点度信息的情况下,给出每个节点的权重。由于节点的移动性,需要调整节点的份额权重。我们根据安全标准分析了我们的方案,并使用ns-2模拟器进行了实验,对我们的方案进行了评估,并与以前的方案进行了比较。结果表明,该方案通过调整每个CA节点的秘密共享权重,提高了证书服务的稳定性。
