云计算安全需求分析研究

摘要

云计算是当下发展迅速的信息技术之一。由于其外包式的服务方式，云计算中的安全问题受到人们格外关注。只有妥善地保障云计算的安全，才不会掣肘云计算的发展和推广。鉴于云计算的复杂性和多面性，文章着眼云计算有别于传统技术的新特点、新趋势，首先提出了考量云计算安全需求的多维视角，随后围绕云计算具体实施过程中的若干关键技术，对云计算中的安全需求进行了细致全面的分析和阐释。%　　Cloud computing is among the fast-developing modern information technologies. Since most cloud services are delivered in an out-sourcing manner, security of the cloud draws particular concerns from its potential users. Security problems should be properly handled before cloud computing can be better received by the public. For better understanding of this issue, this paper brought forward a multi-dimensional view of the security demands in the cloud, and thereafter investigated several critical techniques in a typical implementation of a cloud and their corresponding security demands in details.
