Abstract

The present invention provides a method, a device and a system for device identity authentication. The method comprises the steps of acquiring a device secret key pre-written into a to-be-authenticated device by the to-be-authenticated device, wherein the device secret key is pre-appointed by an authenticating device and the to-be-authenticated device; based on the acquired device secret key, subjecting first data to signature and / or encryption to obtain second data, wherein the first data include random numbers appointed by the authenticating device and the to-be-authenticated device; based on the second data and the identify label of the to-be-authenticated device, generating an authentication code and sending the authentication code to the authenticating device; based on the device secret key corresponding to the identify label of the to-be-authenticated device, subjecting the second data contained in the authentication code to signature verification and / or decryption by the authenticating device; based on a random number obtained through the signature verification and / or decryption process, authenticating the to-be-authenticated device. According to the technical scheme of the invention, the identity authentication problem caused by the reason that the identify label of a device is easily counterfeited or tampered during the authentication process can be solved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of computer application technology, in particular to a method, device and system for device identity authentication. [0003] 【Background technique】 [0004] IMEI (International Mobile Equipment Identity) is solidified in the device when the hardware leaves the factory and cannot be changed or erased. However, since anyone can obtain the IMEI number, that is to say, the IMEI number is in plain text to the outside world. It exists, so it can only solve the problem of device identity in the sales process. After the device is connected to the network, because the IMEI number is easily obtained by the application, the IMEI number is very easy to be forged and tampered with during network identity authentication, which cannot meet the identity authentication requirements of the device on the network. [0005] 【Content of invention】 [0006] In view of this, the present invention provides a device identity authent...
