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.
