Xiangdong Hu · Communications technology · 2008
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.
