Internet of Things equipment identity authentication method, device and system and storage medium

The invention discloses an Internet of Things equipment identity authentication method, device and system and a storage medium, and the method comprises the steps: sending an identity authentication request, so as to enable server equipment to generate a first verification code; receiving the first verification code and generating a second verification code, and when it is judged that the second verification code is consistent with the first verification code, determining that the identity of the server equipment is correct; encrypting the first verification code to generate a third verification code; and sending the third verification code and a pre-configured encrypted data packet to the server equipment, so that the server equipment decrypts the third verification code to generate a fourth verification code, and decrypts the encrypted data packet to obtain equipment verification information when the fourth verification code is judged to be consistent with the first verification code, and when the equipment
