Abstract
Identity information processing method and apparatus are disclosed. The method includes: obtaining customized information of a user process on an integrated chip; determining a target operational firmware preloaded on a reconfigurable chip according to the customized information; generating first process identity information used for verifying the user process based on the target operational firmware and a fixed operational firmware of a non-reconfigurable chip; and providing the first process identity information to a privacy certificate issuing authority for performing firmware legitimacy verification of an operational firmware to determine that an identity of the user process is legitimate according to a result of the firmware legitimacy verification. Therefore, the first process identity information generated for the user process by the integrated chip can prove the legitimacy of the fixed operational firmware of the non-reconfigurable part of the firmware, and also prove the legitimacy of the target operational firmware of the reconfigurable part.
