Embodiment Construction

[0020] A kind of encrypted U disk system with log strong audit proposed by the present invention, combined with drawings and embodiments, is described in detail as follows:

[0021] Overall composition structure of the present invention as shown in Figure 1, comprises the user layer and driver layer that are arranged on host computer (computer) end, and the U disk that is made of memory, safety control module and USB interface control module; U disk passes through standard USB interface Access to the host side, the user layer of the host side performs data and command interaction with the U disk through the USB bus (according to the USB protocol).

[0022] The composition of each component is described as follows:

[0023] user layer

[0024] The user layer provides an interactive interface for user operations, monitors user operations, generates log information and file read and write data to interact with the driver layer; the user layer includes an interactive interface mo...

Abstract

This invention relates to a code U disc system with log check in computer information safety field, which comprises the following parts: user layer and drive layer set in host end; memory, safety control module and USB interface control module, wherein, the user layer is to provide interacting interface user operation to monitor user operation to generate log information and files read data and drive layer for interacting; one u disc for data coding and check.

Description

technical field [0001] The invention belongs to the field of computer information security, and in particular relates to the design of an encrypted U disk system capable of ensuring the safety of important data stored on the U disk and performing real-time and accurate log records on data operations performed by users. Background technique [0002] With the development of computer technology, computer storage media has gradually replaced paper as the main way of information storage. Paperless office has gradually become the main working method of the government, enterprises and military. However, in the current construction of various network systems, we often only care about the security of data transmitted on the network and the security of identity during access, while ignoring the security of information storage, especially the security of mobile storage media. This has become a new and urgent problem in the field of information security. [0003] The research on the s...
