摘　　要：分析了无线传感器网络中广播通信的特点和需要解决的关键问题以及安全协议设计原则.提出了基于公钥算法的全局广播通信安全协议和基于单向密钥链的局部广播通信安全协议,实现了广播通信的可靠性认证,并具有完整性和时效性.从性能分析看,该方案只为传感节点引入了少量的通信负荷、能量消耗和存储空间.The potential characteristic, key security issues and design principles for achieving the security of broadcast communication in wireless sensor network are analyzed. Global broadcast authentication based on public key algorithm and local broadcast authentication based on one-way key chain are proposed respectively, as a conclusion, reliability, integrity, and freshness of broadcast were acquired effectively. The performance analysis showed this method induced less communication load, energy consume and storage space.
