【摘要】Cloud computing is the most popular computing mode of Internet, which features clastic computing,resource virtualization and on-demand service,etc. In this environment,resources such as infrastructures, development platforms and applications are directly provided by could computing center. Users no longer own infrastructures, software and data themselves, but share entire cloud computing resources. This will affects security and availability of could computing environment, and leave it tremendous risks. Security flaws and threats of cloud computing were analyzed in this paper,and a design of computer forensic system based on cloud computing was presented, which resolves security problems of cloud computing using computer forensic techniques, and meets the need of high-performance computing using cloud computing and super computing techniques.%云计算是目前最流行的互联网计算模式,它具有弹性计算、资源虚拟化、按需服务等特点.在云计算的环境中,云计算中心直接提供由基础设施、平台、应用等组成的各种服务,用户不再拥有自己的基础设施、软件和数据,而是共享整个云基础架构.这种方式直接影响了云计算环境的安全性和可用性,给云计算带来了巨大的隐患.在分析和研究云计算环境下的安全缺陷和安全威胁的前提下,提出了一种基
