Mesh network data decryption method, device and system

The invention provides a Mesh network data decryption method, device and system. According to the Mesh network data decryption method provided by the invention, sniffing equipment is added into a Mesh network to obtain related keys including an application key (Appkey), an IV index (IV Index) and a network key (Netkey), then data plaintext is obtained according to the related key decryption data, and finally, the plaintext is analyzed, a Mesh protocol is displayed and network topology is drawn. The problems that a mesh data packet cannot be decrypted and network topology analysis cannot be carried out by a current general packet capture method are solved. 本发明提供了一种Mesh网络数据解密的方法、装置及系统。本发明提供的一种Mesh网络数据解密的方法，将嗅探设备加入Mesh网络，获取相关密钥，包括应用密钥(Appkey)，IV索引(IV Index)，网络密钥(Netkey)，然后根据相关密钥解密数据，获取数据明文，最后分析明文，展现Mesh协议，绘制网络拓扑，解决目前通用抓包方法不能解密mesh数据包和不能进行网络拓扑分析的问题。
