Layered computing virtualization implementing method and device

Abstract

Disclosed are a layered computing virtualization implementing method and a corresponding device. The method comprises virtualizing three independent virtualization layers including a mobile system layer, a virtual volume encryption layer and a virtual application layer to achieve cross-device mobile computing and network-based virtualized working space. The mobile system layer is implemented through a read only mirror system and can be loaded into Ramdisk for running; the virtual volume encryption layer is implemented by establishing a virtual volume, verifying keys, loading the virtual volume as a virtual disk and controlling access of the virtual volume; the application layer is implemented through a virtual machine and a virtual application environment and by extracting Library and a registries required by applications. The virtual application layer is arranged inside the virtual volume encryption layer, and the virtual volume encryption layer and the mobile system layer directly exist in a storage device and are stored separately without mutual containing. The applications inside the virtual application layer can obtain higher speed by taking disks virtualized from memory or a part of the memory as buffer memory.

Description

technical field [0001] The invention belongs to the technical field of security mechanism and virtualization of mobile computing equipment, and can be used to protect equipment and information security and realize fast cross-device use of application programs, application program service (Software as a service, abbreviated as SaaS), and virtualization applications Program permission control. Background technique [0002] Mobile devices and mobile storage devices have been popularized rapidly in recent years, but there are several serious problems, the main ones are security issues, slow speed, and cross-device cloud applications, especially how to implement private clouds. [0003] Background 1. First of all, it is a security issue. [0004] In recent years, with the continuous development of information technology, all kinds of computers emerge in an endless stream, and the application fields of computers have penetrated into all levels of society. According to Professor ...

AI Technical Summary

Problems solved by technology

[0023] Third, the application has great limitations and compatibility

However, the RemoteApp of Microsoft server and the remote XenApp mode dominated by Critex have great compatibility problems.

[0024] Fourth, all user data is stored on the network, how to effectively guarantee the security is a big question

[0026]In short, cloud applications must reduce the cost and technical barriers, and solve the problem of security isolation, otherwise small and medium-sized companies and individuals cannot realize cloud services
