A Survey Of Trusted Computing Specifications And Related Technologies

2003 is the year that the much talked about technologies of Microsoft's Next Generation Secure Computing Base and Intel's LeGrande will be deployed to provide consumers with Trusted Computing. The Trusted Computing Platform Alliance has handed over the batton to the Trusted Computing Group, and new specifications are to be announced soon. But what do these companies and industry groups mean by Trusted Computing, and how will it work in practice? This paper seeks to survey the key points of these technologies and provide a framework for suggesting whether a TCPA/TCG or NGSCB architecture will improve security in an environment and where it may reduce security.
