Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0024] The present invention takes the hardware foundation and security support as the whole system, and uses the self-tailored LINUX operating system and private information processing components as the software foundation of the whole system.

[0025] Such as figure 1 As shown, the physical composition of the USB embedded trusted private information processing device includes a security chip, a Flash memory chip and a security COS. The security chip is connected with the USB port of the computer through the USB interface to complete the high-speed communication with the computer. At the same time, the security chip is connected with the Flash storage chip through the memory interface to realize the security storage function. The security chip can resist physical attacks physically, and the security function of the USB embedded trusted private information ...

Abstract

The invention discloses a USB (Universal Serial Bus) embedded trustworthiness private information processing device and system. The USB embedded type trustworthiness private information processing device is used as a hardware base and a safe support of the whole system, and a self-clipped LINUX operating system and a private information processing assembly are used as a software base of the wholesystem. The USB embedded type trustworthiness private information processing device physically comprises a safety chip, a Flash storage chip and a safety COS (Chip Operating System), and logically comprises a starting region, a USB smart key region, a hiding region and an encrypting region. When a computer terminal is set to be introduced from a USB port and operates after started by the system, the whole computing environment is trustable through trusted guide and measurement; and when the computer terminal is not started and guided by the system, the system can be individually used as an encrypted U disk. According to the invention, the safety problem of individual private information processing is solved and a trustable computing environment is constructed.

Description

technical field [0001] The invention relates to a private information processing device and system, in particular to a USB embedded reliable private information processing device and a portable reliable private information processing system. Background technique [0002] The security of private information has increasingly become a hot security issue that units, enterprises and individuals are concerned about. Users always hope to process sensitive information in a reliable computing environment, such as unit official document information processing, business information processing, personal financial management and personal information (such as pictures, videos and documents), etc. However, in most cases, the simplified structure of the computing platform hardware and software environment for processing private information leads to arbitrary use of resources, especially the executable code can be modified, malicious programs can be implanted, and security threats such as Tr...
