Embodiment Construction

[0136] The Trusted Computing Organization proposes the necessary attributes, functions and characteristics of trusted devices:

[0137] 1. The Trusted Computing Group (TCG, Trusted Computing Group) defines "trusted" as: trustworthiness is an expectation under which a device operates in a specific way according to a specific purpose.

[0138] According to the Trusted Computing Organization's Trusted Computing Platform Standard Implementation Specification, trusted computing should include the following three attributes and functions:

[0139] ①. Ensure the uniqueness of the user's identity, the integrity and privacy of the user's work space.

[0140] ②. Ensure the integrity of hardware environment configuration, OS kernel, services and applications.

[0141] ③. Ensure the confidentiality / integrity of information stored, processed, and transmitted.

[0142] 2. The Trusted Computing Organization has formulated a series of complete specifications for different terminal types and...

Description

technical field [0001] The invention relates to the field of trustworthy, USB storage technology and information security technology, in particular to the field of trusted U disk technology. Background technique [0002] At present, the USB interface has become the standard configuration port of the computer, and the USB mobile storage device, especially the trusted U disk, has been increasingly used in daily work due to its fast storage speed, large capacity, convenient use, and small size. Wide range of applications. [0003] Ordinary U disk is a transparent mobile storage media device, there is no access control for data access, as long as the access party with USB interface can use it without hindrance. Therefore, when U disk brings convenience to people, it also brings two important problems: information leakage and implantation of malicious software. [0004] There are two reasons for U disk to cause information leakage: [0005] ① Due to the leakage of confidential...
