Abstract

In today's very large software systems, it is common to provide software updates over time to correct errors and to improve functionality. In operations with high con dentiality and/or availability requirements, software systems that require frequent updates are not acceptable, since such systems are probably not suf- ciently trusted to allow them to handle sensitive information. Instead it is necessary to have software systems that from the beginning behave properly. This report provides an overview of existing research papers in the area of trusted platforms. The overview is based on a literature review of methods and techniques designed to ensure that the software running on an IT platform can be trusted, in the sense that it behaves as expected. A search was performed in the Scopus database and the articles found were categorized according to several criteria. The study shows that certain categories have received more attention than others and that some technologies (e.g. Trusted Platform Module) dominate. Another observation is that most of the articles, especially those who are not so old, study small and narrow problems and that it is dicult to see how these solutions in a simple way can be combined to create a platform that can be considered reliable.
