2. Taxonomy Of Trust Management Solutions

Current trust management solutions can be classified into three categories. The first category is security enhanced trust management solutions, e.g., trusted computing technology based solutions (TCG, 2003; Yan, 2010). This kind of solutions applies sound security technologies and cryptographic theories to ensure the trustworthiness of a computer, communication or networking system. It deals with root trust module, security policies, credentials, privacy and trust relationships. This kind of solutions provides security enhanced trust management. It mainly solves the security issue in a system, not comprehensively considers the multiple factors of trust, i.e., other properties of trust. Thereby, this solution generally did not ensure other properties of the system related to trust, such as usability and user’s concern. It lacks intelligence to automatically control and maintain dynamically changed trust relationships.
