Mechanism of Minimum Credential Disclosure with Privacy Preserved in TrustBuilder2 Framework

摘要

Present credential disclosure technique requires disclosing more than one credential to establish a trust during Automated Trust Negotiation (ATN), which is time consuming and requires additional burden of credential management. An integrated credential approach is proposed for solving above mentioned problem. This approach is primarily designed for TrustBuilder2 framework. Credential integration approach requires incorporating all the available credentials of an individual into single credential. The privacy of integrated credential is achieved by associating policy that setup conditions for credential disclosure. During ATN the entire content of the credential is not shown only those content which is required for establishing trust are exhibited. These approaches assure the privacy protection while undergoing Trust negotiation.
