| 摘要: |
| 分簇的层次型拓扑控制方式在无线传感器网络中得到广泛研究和应用.然而,由于传感器网络本身所具有的开放性和资源有限的特点,攻击者可以很容易对成簇协议实施有效的误用和破坏.因此,保证成簇协议安全性是其实际广泛应用的基本前提.针对成簇协议所面临的各种安全威胁,提出了一种分布式安全成簇协议,通过网络安全初始化、可信基站的随机数广播和单向密钥链技术来有效地抵御节点伪装和簇首占据攻击、簇成员恶意征募攻击和多重簇成员身份攻击.对协议的安全性和开销进行了广泛和深入的分析,证明了协议的安全性和有效性. |

| Abstract: |
| The cluster-based hierarchical topology control has been widely studied and applied in wireless sensor networks. But because of the open nature and limited resource of the sensor network, clustering protocols are vulnerable to the misuse and disruption attacks from the adversaries. As a result, the security of the clustering protocols is a basic requirement for its wide application. A distributed secure clustering protocol is proposed, in which the secure network initialization, random number broadcast from the base station and one-way hash chain are used to achieve the resiliency against possible attacks including node personating, cluster-head occupying, malicious cluster-member recruiting and multiple cluster-membership attacks. The security and cost of the protocol are evaluated and the results show the resiliency and efficiency of the proposed protocol. |
