Abstract

The invention aims at disclosing a method for managing USBKey unlocking secret keys intensively and safely. Before the USBKeys are delivered to a user for use, an exclusive unlocking secret key is generated for each USBKey, and the exclusive unlocking secret keys are ensured to be safely stored at the same time. When unlocking is required, the USBKeys can be unlocked through the unlocking secret keys. When a large amount of USBKey devices are distributed, the safety of the USBKey unlocking secret keys can be ensured, and safe unlocking is provided for locking of follow-up USBKeys in using process, thereby achieving the purpose.

Description

Technical field

[0001] The invention relates to a method for managing unlocking keys, in particular to a method for centralized and safe management of USBKey unlocking keys. Background technique

[0002] With the development of online banking and online secure transactions, USB Key based on public key cryptography has begun to be used by more and more people.

[0003] The security of the public key cryptography technology itself is guaranteed by algorithms, which can ensure security within a certain time range, but the use of USB Key is protected by a password, and the password is generally not too long for the convenience of remembering. It is often 6 to 8, so the ultimate weakness of security lies in the protection of passwords.

[0004] For this reason, USB Key generally limits the number of password retries, that is, if the wrong password is entered multiple times, the USB Key will be locked and cannot be used. Only by unlocking the key can it be unlocked and reused.
