Trust represents a fundamental, complementary ingredient for the success of security mechanisms in computer science, as it goes beyond the intrinsic, technical aspects of cybersecurity, by involving the subjective perception of users, the willingness to collaborate and expose own resources and capabilities, and the judgement about the expected behavior of other parties. Computational notions of trust are formalized to support automatically the process of building and maintaining trust infrastructures, and mathematical logics provide the formal means to reason about the efficacy of such a process. In this work we advocate the use of two logical approaches to the modeling and verification of the two main tasks at the base of any trust infrastructure: the initial computation of trust values and the dynamic manipulation of such values.

Abstract
Trust represents a fundamental, complementary ingredient for the success of security mechanisms in computer science, as it goes beyond the intrinsic, technical aspects of cybersecurity, by involving the subjective perception of users, the willingness to collaborate and expose own resources and capabilities, and the judgement about the expected behavior of other parties. Computational notions of trust are formalized to support automatically the process of building and maintaining trust infrastructures, and mathematical logics provide the formal means to reason about the efficacy of such a process. In this work we advocate the use of two logical approaches to the modeling and verification of the two main tasks at the base of any trust infrastructure: the initial computation of trust values and the dynamic manipulation of such values.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
