Kind Code:
A1
Abstract:
Provided are an equipment identity authentication method, device and system. The method comprises: equipment being authenticated retrieving an equipment key pre-written in the equipment being authenticated, said equipment key having been agreed on in advance by authenticating equipment and the equipment being authenticated; using said equipment key to sign and/or encrypt a first piece of data so as to obtain a second piece of data, the first piece of data including a random number agreed on by the equipment being authenticated and the authentication equipment; generating an authentication code using the second piece of data and the identifier of the equipment being authenticated, and sending said authentication code to the authenticating equipment. The authenticating equipment uses the equipment key corresponding to the identifier of the equipment being authenticated to perform signature authentication and/or decryption on the second piece of data included in the authentication code; using the random number obtained from the signature verification and/or decryption, the authenticating equipment authenticates the equipment being authenticated. The present invention solves identity authentication problems arising from equipment identifier information being easily forged and tampered with during the authentication process.
