A Multilevel Access Control Scheme for Data Security in Transparent Computing.

In transparent computing, client terminals are rather lightweight, while all other resources (including OSs) are stored on remote servers and delivered on demand to clients via streaming. In this article, the authors propose a Multilevel Access Control Scheme in Transparent Computing (MACTC) to protect user data with different security levels and provide multilevel access control and valid identity authentication. The proposed scheme is effective in multilevel data security, flexible in authorized resource sharing, and secure against various malicious attacks.
