The concept of trusted computing technology is becoming significant in that such technologies are being increasingly available in PCs and mobile devices. With the advent of this technology, one can move from traditional user-only based trust management systems to user and platform-based trust management systems. In this paper, we propose a TCP based trust management and negotiation framework for better security decision making. In this regard, we outline a 3-stage property model that can be leveraged to define policies of different granularities. We then propose how Trust Policy Language (TPL) can be used to create compositions of properties. Finally, the paper discusses the different architectural design choices (such as push, pull and delegation based models) in negotiating trust using these policies and their implications in a distributed Web service based environment.
