Abstract
Ad Hoc network is a multi-hop wireless network, consist of the self-organizing wireless mobile nodes and without fixed infrastructure, but its openness brings “stranger access” problem. Trust management strategy based on trust evaluation can solve such problems. By entrusting trust certificate with trust value, access control policy can be passed to "strangers", and make them able to access the nodes in Ad Hoc network. In order to achieve the trust management based on trust evaluation, this paper proposes policy language for trust management in Ad hoc network. ATPL is defined based on constraint Datalog, realizes the three trust delegation chain of TEAMA by entrusting authorization rules, and completes the calculation of certificate execution and delegation trust value at the same time. This paper defines the syntax of ATPL, discusses the safety of ATPL rules, and proposes the basic safety convention of ATPL and safety statute. By the discussion of ATPL explanatory semantics, this paper solves the legacy security issue, and proves that ATPL rule is safe under various security constraints defined herein.
