The invention discloses an encryption authorization probe and an encryption authorization method. The encryption authorization probe comprises a probe main body and an energy supply antenna; the probe main body is connected with the energy supply antenna; a processing chip is arranged in the probe main body, and the processing chip is electrically connected with the energy supply antenna through a feeder line; and the processing chip is used for providing electric energy for the energy supply antenna and sending data through the energy supply antenna. According to the encryption authorization probe, wireless authorization is achieved through the energy supply antenna, and the authorization implementation process is simplified; and the encryption authorization probe adopts an automatic authorization mode, so that the authorization production efficiency is improved, and the safety of authorization production is improved.
Description
technical field [0001] The invention belongs to the technical field of electronic encryption, in particular to an encryption authorization probe and an encryption authorization method. Background technique [0002] Encrypted and authorized production of electronic equipment is a control measure for product production, that is, only authorized products are allowed to flow into the market. In the production process of modern electronic equipment, the production authorization is generally written by the manufacturer manually into the software key for the electronic equipment, that is, encrypted; Electronic equipment can only be used normally after This encryption and decryption method is not suitable for the relevant electronic equipment of the railway train control system. [0003] The traditional electronic device encryption production authorization is to write the key into the firmware of the electronic device through JTAG (Joint Test Action Group). Whether encrypted info...
