Advances in next generations distributed cyberspace technologies are expected to evolve a global cyberspace marketplace for resource and services. In marketplaces, particularly with the autonomy of users, trading parties differ in many respects, for example their declared agendas, honesty, owned or outsourced resources, and their products. Given these differences and the scale of a global marketplace, trusting the outcome of services or service compositions becomes a challenging endeavor. Personalized autonomic trust management constitutes a powerful solution to such issues. However, current trust systems do not generalize well beyond those problems they were designed for. In addition they are oblivious to individual users' trust requirements. In this paper we propose a generic trust management framework and architecture for trust personalization and autonomic trust management. Our main contributions include: defining and quantifying trust in terms of four parameters: intent capability, integrity and results, and a unified framework for autonomic and personalized trust management. In our simulations, we investigated using trust parameters in BitTorrent protocol. Results showed that, using trust parameters reduce download time and an increase number of finished peers.
