Portable device supporting dynamic configuration of safe operating system in cloud environment

Abstract

The invention discloses a portable device supporting dynamic configuration of a safe operating system in the cloud environment. A cloud server is established, the safe system is stored in the cloud server in a mirroring way, a download interface is provided, a synchronization mechanism is designed among nodes, download verification is set, a physical storage structure changing the portable deviceis run in a known computer via a configuration program, a hidden space is opened, mirroring download and file extraction are carried out, and the system is configured automatically. Compared with theprior art, the portable device has the advantages that the mirroring system is stored in a cloud platform, the version and functions of the system can be changed instantly according to requirements, system configuration is completed automatically needless of manual setting, original files in the portable device are not influenced after configuration, after use, the system can recovered to a statebefore use, the privacy and safety are ensured, a network node forwarding manner is used, and safe transmission of data is realized.

Problems solved by technology

[0002] With the advent of the information age, computer technology is constantly developing and improving, and computers are also widely used in various fields of social life and work. With the development of social informatization, computers have gradually become indispensable in people's daily life. Role, with people's dependence on computers, computers have gained a broader market development space, but while computer technology is developing, information security has become a huge problem hindering its development. The main problems of information security are trace removal and Data transmission, even if the file is deleted on the computer, there will still be data traces retained, resulting in data leakage; in the process of data transmission, the data is easily intercepted, and it is easy to be directly sent from the client to the receiving end. Locking the client address and the receiving end address, thereby causing harm to information security, in order to ensure information security, a large amount of research work has turned to data operation and data encryption transmission through portable systems and multi-layer network node forwarding. One of the safest, most effective and hottest research directions

[0003] In the field of portable systems, WindowsToGo provided by Microsoft can deploy the system to portable devices regardless of the operating system running on the computer, but it needs to put the entire windows system into the portable device, and will install the required software when the computer starts for the first time. The driver is too cumbersome to use, and its entire operating system runs in a portable device, which is limited by the performance of the device

[0004] Products such as Chinese cabbage and Lao Maotao can write the Windows PE system into the U disk to achieve maintenance. The PE system can be carried around, but its PE system is a specific system and cannot be customized, and the PE system is Made in advance, deployed when unavailable, deleted when used up

[0005] The U.S. Department of Defense released "Lightweight Portable Security" (abbreviated as LPS, Lightweight Portable Security Tool), which writes the computer system into a read-only USB flash drive, and at the same time the system runs in the computer's memory, which can ensure privacy and security during operation. However, its U disk is intelligently used in the system, and cannot be changed, and the system needs to be written in advance, and the functions in the system cannot be changed immediately according to the demand
