Abstract
This application discloses a communication method and a communication device. The communication method includes: receiving a first message, the first message including a first digital signature and first verification information; verifying the first digital signature based on the public key of a network node and the first verification information to obtain a first verification result; and indicating that the first digital signature has passed verification based on the first verification result, thereby determining that the first message is a message sent by the network node. Implementing this application provides a method for authenticating messages sent by a network node by an A-IoT device, improving communication security.
