Embodiment Construction
[0038] The technical solution of the present disclosure will be described in further detail below with reference to the drawings and embodiments.
[0039]In related technologies, it is often necessary for the IoT terminal to encrypt the terminal DUC with the application time and IMEI as the key, and then send it to the platform for registration, and the platform verifies the legitimacy of the terminal DUC. DUC is the displacement code of the IoT terminal equipment, which is unique and corresponds to the IoT monitoring terminal one by one. After the verification is passed, it is sent to the terminal as a key according to the current time, and the terminal uses the received time and the IMEI of the terminal as the key to encrypt the message.
[0040] In such an encrypted communication method, when the terminal uploads a message, the platform can obtain the IMEI code of the terminal communication module, and the attacker can also obtain the IMEI code, so the attacker can also gen...
