一种改进的基于位置的攻击容忍WSN安全方案
Improved Location-Based Compromise-Tolerant Security Mechanisms for Wireless Sensor Networks
摘要
Abstract
Identity-based encryption has been widely used for wireless sensor networks. The Research on the IBE employed location-based compromise-tolerant security mechanisms is hot. However,there are two issues for the current research on such IBE-based scheme,pairing-based computation for IBE costs so large,and location of each node is supposed to be fixed which loses the permission of node movement. In this paper, a lightweight IBE scheme named TinyCKE is firstly proposed for WSNs,which is based on ECC Combined Key Encryption and is more applicable for resource-constrained WSN nodes than that of pairing-based IBE. Using TinyCKE, an improved location-based compromise-tolerant security scheme is then proposed. It depends on the uniform management of the node location range and the private key lifetime. The proposed solution can not only support the node movements in the legitimate location ranges with lightweight ECC-based authentication supported,but also limit the possible attack of malicious node into one period of key update lifetime. It is well compromise-tolerant for both location and key validate time of nodes.关键词
