无线传感网络中抵抗节点复制攻击新方法

Novel approach against node replication attacks in wireless sensor networks

针对伏飞等人提出的LTB(Location and Time Binding)方法的不足:不能完全阻止复制节点加入传感网络;不能阻止新加入节点和复制节点建立共享密钥,提出了一个在传感网络中抵抗节点复制攻击的新方法,该方法通过把传感网络划分成一系列有效区域并把节点的密钥与身份标识和部署位置绑定起来,在共享密钥建立时阻止部署在有效区域外的复制节点建立共享密钥,在复制节点通信时检测出有效区域内的复制节点。该方案能有效地解决LTB带来的安全隐患且和LTB具有相近的通信、存储开销。

To solve the limitation that LTB can＇t completely stop replica nodes joining the sensor network and new nodes establishing shared key with the replica nodes,this paper presents a novel approach against node replication attacks.This scheme could prevent replica nodes which deployed in noneffective range establishing shared key and detect the replica nodes which deployed in effective range when replica nodes communicate with others by dividing sensor network into a series of effective range and binding the key material with ID and deployment location.It could effectively solve the potential hazard of LTB and it possesses a similar communication and storage overhead with LTB.
