摘要
无线传感器网络是一门前沿技术,具有非常广泛的应用前景,特别是在军事、环境科学、医疗健康﹑空间探索和灾难拯救等众多领域。作为一种网络,其安全问题显得很重要,而Sybil病毒攻击在传感器网络(wsn)中是比较突出的。针对这一问题,探讨了几种基于密钥预分配来防御sybil攻击的方案。分析表明:多空间成对密钥分配技术是其中最好的。
Wireless sensor network is a front technology, has a promising future in such applications as military, environment, health, space exploration and rescue. As a network, its security is an important issue, Sybil attack in this network is especially serious. According to this, this paper investigates several schemes based on key pre-distribution appling for defense against sybil attack. The analysis indicates that the multi-space pairwise key distribution is the best one.
