无线传感器网络安全广播通信研究

Research of Safe Broadcast Communication in Wireless Sensor Networks

  • 摘要: 无线传感器网络被广泛应用于环境观测和预报,广播通信安全是一个极具挑战性的问题。文章提出了一种新的基于消息验证码(MAC)的广播认证方案。该方案充分利用目前无线传感器网络部署中广泛使用的分簇结构,结合1-bit/密钥的MAC,在合理利用传感器网络有限资源的情况下,实现了广播通信的可靠认证,并具有完整性和时效性。

     

    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.
