Trusted authentication method for intelligent lamp post

The invention provides a credible authentication method for a smart lamp post, and belongs to the technical field of smart city Internet of Things, and the credible authentication method comprises an initialization stage, a registration stage, a time synchronization stage, a data encryption stage, a data decryption stage, an identity authentication stage, and a smart lamp post terminal data collection or cloud platform reverse control stage. In the initialization stage, a global master key is generated, in the registration stage, a smart lamp post terminal and an edge gateway register on a cloud platform and obtain the global master key and a unique identity ID identification code, in the time synchronization stage, the time consistency of nodes of the system is ensured, and in the encryption/decryption stage, plaintext data and ciphertext data conversion is realized. The identity authentication stage realizes credible authentication of node identities, and the intelligent lamp post terminal data acquisition
