Customer data multi-encryption system and method in intelligent Internet of Things energy system

The invention discloses a client data multi-encryption system and method in an intelligent Internet of Things energy system. The method comprises the following steps: terminal equipment registers to a verification server according to identity information of the terminal equipment, and after registration succeeds, the terminal equipment interacts key information with the verification server; the terminal equipment encrypts the type of the client data, the client data and the identity information by adopting a public key to generate a first ciphertext; encrypting the first ciphertext according to a first encryption rule agreed with the edge gateway in advance to obtain a second ciphertext; encrypting the second ciphertext according to a second encryption rule agreed with the edge gateway in advance to obtain a third ciphertext; sending the third ciphertext to an edge gateway; and the edge gateway searches a second decryption rule and a first decryption rule corresponding to the terminal equipment to decrypt the
