Research on Data Security Access Model of Cloud Computing Platform

Cloud computing is a new Internet application mode, has very large scale, virtualization, high reliability, versatility and low cost characteristics. Cloud computing technologies can dynamically manage millions of the computer resources, and on demand assign to a global user. It appears to completely change the old Internet application mode. Since the data was stored in the remote cloud computing platform, thus brought new challenges to information security, for example, disclosure of data, hacker attacks, Trojans and viruses seriously threat user data security. A strict information security scheme must be established, then users can use cloud computing technologies. From based on USB key user authentication, based on attributes access control and data detection, the data security access of cloud computing platform was studied, to provide a secure solution for the user.
