Trust assessment-based adaptive trust negotiation system and method

Abstract

The invention discloses a trust assessment-based adaptive trust negotiation system and a trust assessment-based adaptive trust negotiation method. The system comprises a plurality of trust negotiation devices, wherein the trust negotiation devices comprise a requesting party trust negotiation device and a requested party trust negotiation device; the trust negotiation devices also comprise a certificate device, an access control strategy device, a trust assessment device, a consistency checker device, a trust negotiation strategy device, a negotiation protocol device and a security interaction device; and the trust negotiation strategy device performs trust negotiation control on each device based on the trust level provided by the trust assessment device. Therefore, the invention provides the trust assessment-based adaptive trust negotiation system and the trust assessment-based adaptive trust negotiation method, which can dynamically adjust the access control strategy and the negotiation strategy according to the trust assessment result so as to effectively meet the demands of efficiency and security in the trust negotiation.

Description

technical field [0001] The invention relates to a trust negotiation system and method, in particular to an adaptive trust negotiation system and method based on trust evaluation. Background technique [0002] In order to solve the problem that it is difficult to establish a trust relationship between unfamiliar subjects in an open environment, Winsborough et al. proposed the concept of "automated trust negotiation (ATN)" in 2000, which is "interactive disclosure through credentials and access control policies". , the resource requester and provider automatically establish a trust relationship". At present, trust negotiation, as a new trust management method, has attracted extensive attention from the international academic community and has become an important research direction. Seamons of ISRL Laboratory of BYU University and Winslett of UIUC University jointly undertake the research project TrustBuilder[3] of ATN. They have carried out a lot of research work and laid a s...

[0004] Refer to the publication number CN101719824A, the invention title is a patent for a trust evaluation system and method based on network behavior detection, which introduces the trust evaluation system and method, and see the publication number CNi01707613A, the invention title is authentication based on trust negotiation System and user login and collaboration system and method patents, but the first one of the above-mentioned patents guarantees the accuracy of trust assessment. On the basis of ensuring the accuracy of trust assessment, the latter one only guarantees the security of trust negotiation and cannot guarantee trust at the same time. Negotiation efficiency, so a trust negotiation system that can guarantee both efficiency and security is needed
