ABSTRACT:
A novel user-centric authorisation framework suitable for e-commerce in an open environment is proposed. The credential-based approach allows a user to gain access rights anonymously from various service providers who may not have pre-existing relationships. Trust establishment is achieved by making use of referrals from external third parties in the form of Anonymous Attribute Certificates. The concepts of One-task Authorisation Key and Binding Signature are proposed to facilitate pseudonymity in authorisation service. These mechanisms enhance user privacy and tackle the problem of scalability in identity-based access control systems.
