Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; A kind of Trusted Computing device with USB interface comprises USB interface, the interface conversion circuit that is connected with said USB interface; And the fingerprint module that is connected with said interface conversion circuit, microprocessor, creditable calculation modules and 2.4G wireless network communication module
Said interface conversion circuit module is used for all converting the interface of creditable calculation modules and the interface of fingerprint module into USB interface;
Said fingerprint module is used to import fingerprint, and transmits it to said creditable calculation modules preservation;
Fingerprint module is combined with creditable calculation modules, and creditable calculation modules stored fingerprint template when the user uses this USB module, needs the checking fingerprint, could use creditable calculation modules then, increases the security that Trusted Computing is used.
Said creditable calculation modules; Comprise multiple Trusted Computing chip; Said Trusted Computing chip comprises TCM (Trusted Cryptography Module; Credible password module), (the TPM safety chip is meant the safety chip that meets TPM (Trusted Platform Module, reliable platform module) standard to TPM; It can be protected PC effectively, prevent that the disabled user from visiting) and/or TPCM (creditable calculation modules), be used to the credible tolerance, trusted storage and the credible report that provide Trusted Computing required;
Said microprocessor is used to verify the correctness through the fingerprint of said fingerprint module input; Said microprocessor adopts ASIC (Application Specific Integrated Circuit; Application-specific IC) chip, CPLD (Complex Programmable Logic Device; CPLD) chip or FPGA (Field-Programmable Gate Array; Field programmable gate array) chip, microprocessor is responsible for driving whole Trusted Computing device after the USB power supply, and whether the input of checking fingerprint module is consistent with expected result.
