一种基于代理的自动信任协商模型
Agent based automated trust negotiation model
摘要
Abstract
To enhance the practicability of the trust negotiation system,an agent based automated trust negotiation model (ABAM) is proposed.The ABAM introduces an agent to keep the negotiation process with no human intervention.Meanwhile,the ABAM specifies the format of a meta access control policy,and adopts credentials with flexible format to meet the requirements of access control policies instead of disclosing the whole contents of a certificate.Furthermore,the ABAM uses asymmetric functions with a high security intensity to encrypt the transmitting message,which can prevent information from being attacked.Finally,the ABAM presents a new negotiation protocol to guide the negotiation process.A use case is studied to illuminate that the ABAM is sound and reasonable.Compared with the existing work,the intelligence,privacy and negotiation efficiency are improved in the ABAM.关键词
