Towards ubiquitous computing via secure desktop service

Among all the approaches enabling remote access to the private information stored at some static locations, one approach, often referred to as remote desktop control, provides the most intuitive form of such operations. With remote desktop control, people are able to access their personal desktops remotely and operate on them in the same way as they do when sitting in front of their consoles. A side-effect of this approach is that the potential damages caused by misuses get more severe, and security issues hence become more important. In this paper, a scheme of authentication via mobile phones is proposed to make the approach of remote desktop control more secure. Another benefit of this scheme comes from the globally deployed telecommunication network, which makes the application truly ubiquitous
