Abstract

A USB (universal serial bus) Key equipment identifier comprises a processor module, wherein the processor module is connected with a USB interface module and a storage module; USB Key equipment is connected with a PC (personal computer) by the USB interface module; and the storage module is used for storing encrypted operation codes. The USB Key equipment identifier has the advantages that USB connection between the USB Key equipment and the PC can be controlled by a preliminary identification result of the processor module on the USB Key equipment, the using safety performance of the USB Key equipment is improved, and the loss is reduced; operation on the USB Key equipment is configured by the PC, and safety and reliability are guaranteed; the USB Key equipment is secondarily identified by the encrypted operation codes in the storage module, the safety performance is strengthened, the encrypted operation codes can be loaded and configured in real time, and reliability is high; and a self-destruction module is arranged on the USB Key equipment identifier, when the identifier is invaded by external force, a self-destruction function is started, so that the identifier is protected, and the safety performance is further improved.

Description

technical field [0001] The invention relates to a USB Key device discriminator. Background technique [0002] With the advancement of Internet technology, many fields such as banking and personal payment, and access control authority management use USB Key as a key for identity verification. At present, the USB Key itself is not easy to be attacked to steal information, but the device that reads the USB Key is easy to be attacked and infected with viruses. Especially ATM this class equipment, its USB interface is open, the lawless person inserts the USB equipment with virus nature easily and attacks ATM, causes loss to the bank. Contents of the invention [0003] The invention provides a convenient and safe USB Key device identifier. [0004] The technical scheme adopted in the present invention is: [0005] A USB Key device discriminator, comprising a processor module, the processor module is connected with a USB interface module that realizes that the USB Key device i...
