This paper presents an anonymous access scheme for electronic-services. The scheme based on tickets supports efficient authentications of users, services and services providers over different domains. Tickets are issued by a Credential Centre through a signature protocol and are used to verify correctness of the requested services as well as to direct billing information to the appropriate user. The service providers can avoid roaming to multiple service domains, only contacting the Credential Centre to certify the user's ticket since tickets carry all authorization information needed for the requested services. The user can preserve anonymity and read a clear record of charges in the Credential Centre at anytime. Furthermore, the identity of misbehaving users can be revealed by a Trusted Centre.
