Abstract	In this paper a generalized trust calculation mechanism is proposed which could be used to And out the trust values of various entities involved in a pervasive environment globally. The trust values calculated between the entities are stored in a global data store. This trust value can be used as a basis for future transactions of the entity concerned. The global data store can be maintained by a centralized authority to avoid any ambiguity. Since the global data store contains the trust value of all the users of the environment, these trust values are more accurate than that which has been calculated through recommendations. This also obviates the necessity for entities to know each other beforehand, which is a prerequisite in the case of recommendations. The performance of the proposed scheme is evaluated in comparison with existing recommendation based trust models. The comparison reveals that the global trust management approach performs better, than the former approach while also retaining the same level of the security of interactions, and quickly adapting to changes in the environment.
