移动自组网中一种安全的最高节点度分簇算法

SHDCA:a Secure Highest Degree Clustering Algorithm in Mobile Ad hoc Networks

移动自组网的固有特征导致它非常容易受到各种攻击,本文着重考虑在移动自组网中广为使用的分簇技术的安全问题.首先分析分簇算法可能面临的攻击,提出一种安全的最高节点度分簇算法(SHDCA),包括基于AOA的位置验证和局部信誉机制,前者验证节点的位置信息,后者则来检测并隔离攻击者.安全分析和仿真实验表明,SHDCA能够有效的实现预定的安全目标,并且在安全和性能开销上达到了合理的折中.

Mobile Ad hoc Networks are particularly vulnerable for their features, and this paper focuses on the security problem of clustering technique which is widely used in MANET. We analyze the attacks that clustering algorithms will meet, and de- sign a Secure Highest Degree Clustering Algorithm （SHDCA）, including AOA based location verification and local reputation system. Through the security and performance analysis, we demonstrate that SHI＇）CA is efficient with respect to the security capability it provides and SHDCA also allows a tradeoff between security and performance.
