the authentication module sends a secret key authentication request to the cloud server, wherein the secret key authentication request comprises: the serial number, the device registration information encrypted with the cloud public key, and the device public key.
S3: the cloud server receives the key authentication request, acquires first equipment registration information from the key authentication request, compares whether the first equipment registration information is consistent with locally stored standard equipment registration information, if so, executes S4, and otherwise, sends out an alarm.
The cloud server receives the secret key authentication request, decrypts the first equipment registration information by using a cloud server private key, locally finds out standard equipment registration information stored by the cloud server through the serial number, compares the standard equipment registration information with the serial number, encrypts a confirmation message by using an equipment public key after the comparison is consistent, and sends the confirmation message to the authentication module.
Specifically, the key authentication request includes a serial number, first device registration information encrypted by using a cloud server public key, and a device public key. Correspondingly, a cloud server private key is stored in the cloud server, and the cloud server can decrypt the first device registration information encrypted by the server public key by using the cloud server private key to obtain the plaintext first device registration information. Meanwhile, a 'serial number-standard equipment registration information' lookup table is stored in the cloud server, namely, the cloud server can locally find the standard equipment registration information uniquely corresponding to the serial number according to the obtained serial number, so that the cloud server can obtain the first equipment registration information and the standard equipment registration information according to the information contained in the key authentication request, and then compares whether the first equipment registration information and the standard equipment registration information are consistent, if so, the authentication module initiating the request is indeed an authentication module which is registered and recorded in the cloud server instead of a false authentication module or a fake authentication module, and therefore the safety of communication after disguising is ensured.
Specifically, a premise for realizing the invention is that firstly, a serial number and a license which are in one-to-one correspondence are generated, wherein the license comprises standard equipment registration information, an equipment public key and an equipment private key, then, the license is respectively input into an authentication module and a cloud server, the serial number is input into the cloud server, and at least a lookup table of 'serial number-standard equipment registration information' or similar 'serial number-standard equipment registration information' corresponding relation logic is formed in the cloud server. In order to facilitate the generation and storage, the serial number and the license which are in one-to-one correspondence can be directly generated in the cloud server.
S4: the cloud server encrypts the confirmation message once and sends the confirmation message after encryption once to the module;
specifically, the cloud server encrypts the confirmation message by using the device public key and sends the confirmation message to the authentication module.
S5: the authentication module receives the confirmation information after the primary encryption, decrypts the confirmation information, performs secondary encryption on the confirmation information, and sends the confirmation information subjected to the secondary encryption to the cloud server;
specifically, the authentication module stores an equipment private key, decrypts the confirmation message encrypted by the equipment public key by using the equipment private key, secondarily encrypts the confirmation message by using the cloud server public key stored by the authentication module, and sends the secondarily encrypted confirmation message to the cloud server.
S6: and the cloud server receives and decrypts the confirmation information of the secondary encryption, compares whether the received confirmation information is consistent with the confirmation information sent by the cloud server, completes authentication if the received confirmation information is consistent with the confirmation information sent by the cloud server, is disconnected with the authentication module, and sends an alarm if the received confirmation information is not consistent with the confirmation information sent by the cloud server.
Specifically, the cloud server decrypts the twice-encrypted confirmation information by using a cloud server private key to obtain the confirmation information.
According to the invention, the cloud server firstly sends the primary encrypted confirmation information to the authentication module, the authentication module decrypts the primary encrypted confirmation information to obtain the confirmation information, the confirmation information is encrypted for the second time and then sent to the cloud server, and the cloud server decrypts the confirmation information again.
Example two
