摘要
基于MAC(Message Authentication Codes,消息认证码)和无线传感器网络的组密钥管理特点,提出一种轻量级的组播源认证方法LAMA(Lightweight Approach to Multicast Authentication).通过与其他方法进行性能分析和数据对比表明,LAMA的计算开销和通信开销等参数都处于合理的范围内,是一种适用于无线传感器网络环境的安全、有效方法.
LAMA (Lightweight Approach to Multicast Authentication) was proposed based on MAC (Message Authentication Codes) and group key managements of WSN (Wireless Sensor Networks).Comparison of the performance with those of other schemes shows both computation and communication overheads of LAMA are in reasonable scopes,so it is secure and efficient to WSN.
