METHOD FOR REALIZING SMART TOKEN CRYPTOGRAPHY APPLICATION INTERFACE ON BASIS OF TPM

WIPO Patent Application WO/2024/036832

A1

Disclosed in the present invention is a method for realizing a smart token cryptography application interface on the basis of a TPM. The method comprises: a. using a TPM security chip as underlying hardware of a smart IC card or a smart token, wherein the smart IC card or the smart token is a TPM device, a kernel of an operating system of each TPM device comprises a TPM device drive, and an application program, an SKF interface providing layer, an SKF interface service layer and a trusted software stack (TSS) are deployed in a user space of the operating system of each TPM device; b. the operating system interacting with the TPM security chip by means of the TPM device drive; c. storing SKF application metadata, SKF container data and SKF file data of the device in a non-volatile storage area, which is provided by the TPM security chip, and creating an authorized-access mechanism; and d. when an SKF interface is called, executing an SKF interface availability check first. The present invention provides, for the availability of an SKF interface, a secure and trusted hardware-level protection mechanism for system integrity, in which mechanism a TPM is used as a core.
