摘要：

Wireless sensor networks are being deployed for some practical applications and security of them has received considerable attention. It is an important challenge to find out suitable key protocol for wireless sensor networks due to limitations of power, computation capability and storage resources. The paper proposed a novel secret shared scheme for wireless sensor networks. In the proposed scheme, random pair of sensor nodes shares some secrets for their communication. Analyses of the proposed scheme demonstrate that it is efficient for wireless sensor networks. Compared with random key predistribution scheme, the proposed scheme solves the problem that random key predistribution scheme cannot always ensure that random two nodes in wireless sensor networks can get some common secrets when they communicate. Combining the proposed scheme with echo-back approach, we construct a secure multiple paths message forwarding mechanism. Analysis and simulation results show that the mechanism can defense rushing attack launched by big power adversaries efficiently.
