All messages are encrypted and authenticated using two types of keys. One key type is for the network layer communication, such that all communication within a mesh network would use the same network key. The other key type is for application data. Separating the keys for networking and applications allows sensitive access messages (e.g., for access control to a building) to be separated from non-sensitive access messages (e.g., for lighting). There are no unencrypted or unauthenticated messages within a mesh network.
所有消息都使用两种类型的密钥进行加密和身份验证。一种密钥类型是网络层通信，这样一个网状网络中的所有通信都将使用相同的网络密钥。另一种密钥类型用于应用程序数据。将网络和应用程序的密钥分开，可以将敏感的访问消息(例如，对建筑物的访问控制)与非敏感的访问消息(例如，用于照明)分开。在网状网络中没有未加密或未经身份验证的消息
