Remote de-locking method of information safety device

Abstract

This invention discloses a remote unlocking method for information security devices including: a holder of an information security device gets correlated hardware information from an information securuioty device then to send the authentication information containing hardware information to a hardware resuming information generation device, which generates hardware resuming information based on the authentication information and the holder realizes unlocking with the resuming information.

Description

technical field [0001] The invention relates to a remote unlocking method, in particular to a remote unlocking method for information security device firmware. Background technique [0002] Under normal circumstances, the sales model of information security equipment products that use software encryption protection and identity verification, including mobile phones and smart cards, is publisher-user, and ordinary users forget the PIN code set by themselves (the password of the information security equipment, used to Prevent others from misappropriating. When the user enables the PIN code, it is equivalent to adding a password to the information security device, and the user can modify the PIN code by himself) or after the PIN code is locked, it needs to be unlocked by the issuer or restore the original PIN code. This process requires The issuer uses the PUK (Personal Unlock Key), which is used to unlock the information security device locked due to the wrong input of the PIN...

Problems solved by technology

Each PIN code corresponds to a different PUK code. When the PIN code is entered incorrectly for many times, the information security device is locked and needs to be unlocked by entering the PUK code. In the prior art, some people also refer to the PUK code as SOPIN code) code verification, but If the issuer forgets the PUK code, the work of unlocking or recovering the PIN code cannot be completed, so the unlocking cannot be performed. At this time, the issuer needs to contact the manufacturer to realize the recovery of the PUK code

[0003] The traditional way is that the hardware is scrapped or the publisher returns the hardware device to the manufacturer. This process not only consumes a lot of manpower and material resources, but also the hardware device is easily damaged or lost during long-distance transmission. Equipment is causing unnecessary trouble
