This paper proposed a lightweight collaborative authentication algorithm （ LCAA） . The algorithm used some simple symmetric keys and generating functions and node wake-up mechanism to provide the basic security for smart dust sensor netorks. The algorithm could further improve network security and could be applied to general wireless sensor networks through collaborating with other authentication algorithm. The simulation experiments show that the algorithm has a good safety and energy efficiency,suitable for smart dust sensor network.
