Establishing Trust Beliefs based on a Uniform Disposition to Trust

Abstract : Trust based access control models have recently attracted significant interest in the area of pervasive computing. In several trust based models, organizations are required to establish a set of trust beliefs regarding their neighboring nodes. In an organization there may be multiple administrators or the administrators may change with time. When multiple administrators contribute to the creation of the set of trust beliefs of an organization, inconsistencies may occur due to variations in their personality or disposition to trust. In this paper we introduce a novel method for establishing the set of trust beliefs, which is likely to be more consistent. The proposed solution attempts to tie the quantification of trust not to the multiple dispositions to trust of the administrators but to a uniform disposition to trust of the organization. Having administrators evaluate the trustworthiness of neighboring nodes in relation to other nodes and using a mapping function for assigning quantitative values are the highlights of the method.
