摘要
研究了目前传感网存在的安全隐患,针对主要攻击手段提出一种简单可行的安全方案。该方案包括两部分:1.以帧的序列号为初始向量,采用AES算法对相应的PANID(个人区域网络标识符)进行加解密;2.根据接受帧的序列号对接收帧的有效性进行判断。由此,该方案在保证PANID的机密性、防止伪装攻击方面有着比较显著的效果。
For the ZigBee sensor network is still not safe enough, this article proposes a simple feasible security solution. It contains two parts. First, with the frame series number as the initial vector, using the AES algorithm encrypts /decrypts the cor responding PANID. Second, judge the validity of the frame received according to the series number. Actually, this solution has a significant effect on ensuring PANID security and preventing disguised attack.
