Abstract: Wireless sensor networks are broadly used in environment detection and prediction,security of broadcast communication is an challenging problems in it. This paper proposed a new broadcast authentication scheme based on MAC. Using clustering structure widely deployed in wireless sensor networks and 1-bit per key MAC,this scheme assured reliability, integrity and freshness of broadcast communication with moderate cost of limited resources.-
