云图书馆虚拟环境可信验证过程的设计与实现

Design and Implementation of Trustworthiness Validation in Cloud Library Virtualized Environment

【目的】通过对云图书馆虚拟环境进行可信验证保证用户资源与服务所在的虚拟环境的可信。【方法】建立基于可信第三方的验证模型,通过可信第三方分别对用户和云图书馆平台进行可信验证的方法,设计并实现云图书馆虚拟环境的可信验证过程。【结果】能够以较小的系统开销确保虚拟机请求过程、分配过程以及启动过程的可信,保证云图书馆平台分配给用户的虚拟机是可信的。【局限】虚拟机使用、虚拟机迁移等过程的可信验证所带来的系统开销,有待进一步实验和验证。【结论】本研究能够向用户保证其所请求的虚拟机的可信,建立用户与云图书馆平台的信任关系。

[Objective] To ensure the trustworthiness of cloud library virtualized environment which contains users＇ resources and services by trustworthiness validation. [Methods] By establishing a validation model in which the Third Trusted Party respectively validates the cloud library platform providers and users, this paper designs and implements the trustworthiness validation process of cloud library virtualized environment. [Results] This paper can ensure the trustworthiness in process of request, allocation and startup of virtual machine with little overhead, and ensure that the virtual machine assigned to users is trusted. [Limitations] The overhead of validation in virtual machine＇s usage and migration needs to be verified. [Conclusions] The research can ensure trustworthiness of virtual machine to build the trustworthiness between cloud library users and platform providers.
