Trusted computing provides a new way to solve system security problems. The trusted cryptography function access methods defined in the current domestic and international standards are generally API interface methods, such as trusted software stack (TSS) in TCG standard and TCM service module (TSM) in Chinese national standards. These interfaces are very complicated. And there are compatibility issues between each other, affecting the development and promotion of trusted computing. In order to solve these problems, a message-driven hierarchical trusted cryptography service framework is proposed, which can shield complex trusted root access details through module encapsulation, simplify interfaces, solve compatibility problems, and implement distributed and collaborative trusted root access in a message-driven ways. Finally, two examples are given to illustrate the feasibility of the framework, the generality of the modules in the framework, and the effect of the framework in simplifying the implementation of the trusted cryptography mechanism.
