Embedded trusted computing development device

Abstract

The invention discloses an embedded trusted computing development device. The embedded trusted computing development device comprises a USB interface module and a central processing unit; the USB interface module is in communication connection with an outer computer, is used for receiving control data sent by the computer according to a communication protocol and supplies electricity for the device; the central processing unit is connected with the USB interface module and used for analyzing the control data, obtaining user commands and sequentially conducting judgment operations on the user commands, after corresponding file operations are conducted according to judgment results, corresponding response data are returned to the USB interface module, and the USB interface module sends the response data to the computer. According to the embedded trusted computing development device, guidance of development and debugging of a trusted computing security module and firmware are facilitated.

Description

technical field [0001] The invention relates to the technical fields of information security and trusted computing, in particular to an embedded trusted computing development device. Background technique [0002] The rapid development of computer and communication technology makes the status of information security increasingly important. The current information security technology mainly relies on the combination of strong cryptographic algorithms and keys to ensure the confidentiality and integrity of information, the uniqueness of entity identity and the non-repudiation of operations and processes. However, various password algorithms are not absolutely safe, and many users do not know how to set up these password protection mechanisms. More importantly, although these technologies can block hackers and virus attacks to a certain extent, they cannot prevent insiders from attacking Leakage, theft, tampering and destruction of key information. [0003] In order to improve...

Problems solved by technology

At present, in the process of developing trusted products, most people use software simulation for development. It is difficult to fully simulate the trusted computing security chip and its platform, and the existing development boards for research and development often use trusted chips.

Rather than discrete components, it is not convenient to measure the signals transmitted by each component on the development board, which affects the efficiency of research and development
