Method for Implementing IoT Registration and System therefor

A method for implementing an IoT registration, wherein the method comprises:

• a push service registration process and a terminal device registration process, the push service registration process comprises the following steps:
• S1) generating, by a push service, a registration request according to a device identification of a terminal device that needs to be registered, corresponding device attribution information and a push service public key, and sending the registration request to an authentication center, the device attribution information comprising a device public key, identity information of the push service, and an address of the push service;
• S2) saving, by the authentication center, the device identification, the corresponding device attribution information and the push service public key in the registration request received, generating a first nonce, generating a registration response according to the device identification in the registration request and the first nonce, and returning the registration response to the push service;
• S3) parsing, by the push service, the registration response received, generating protocol data according to the device attribution information, the first nonce obtained by parsing, and preset push service timeout time, generating an identity authentication request according to the protocol data, and sending the identity authentication request to the authentication center;
• S4) verifying, by the authentication center, the identity authentication request according to the push service public key, and saving the protocol data in the identity authentication request in correspondence with the device identification if a verification succeeds, then executing Step S5;
• S5) determining, by the authentication center, whether the push service timeout time in the identity authentication request is within a preset range, if yes, executing Step S6, otherwise, generating another push service timeout time within the preset range, and replacing the push service timeout time in the protocol data with the another push service timeout time generated, then executing Step S6;
• S6) generating, by the authentication center, an identity authentication response according to the push service timeout time and returning the identity authentication response to the push service;
• and
• S7) saving, by the push service, the push service timeout time in the identity authentication response;
• the terminal device registration process comprises the following steps:
• T1) generating, by the terminal device, a loading request according to the device identification, and sending the loading request to the authentication center;
• T2) determining, by the authentication center, whether corresponding protocol data is saved according to the device identification in the loading request, if yes, executing Step T3, otherwise, returning error information to the terminal device;
• T3) generating, by the authentication center, a second nonce, saving the second nonce in correspondence with the device identification, generating a loading request response according to the second nonce, and returning the loading request response to the terminal device;
• T4) parsing, by the terminal device, the loading request response received, generating an identity authentication request according to a second nonce obtained by parsing, the device identification and a device private key, and sending the identity authentication request to the authentication center;
• T5) verifying, by the authentication center, the identity authentication request according to a device public key in the saved protocol data and the second nonce, if a verification succeeds, generating an identity authentication request response according to an address of the push service in the saved protocol data, and returning the identity authentication request response to the terminal device, then executing Step T6;
• if the verification fails, returning error information to the terminal device;
• and
• T6) parsing, by the terminal device, the identity authentication request response to obtain the address of the push service, and saving the address of the push service in correspondence with the device identification.
