This article proposes a system in which a Global System for Mobile (GSM) communication user can access and be authenticated to third party services with total anonymity as far as the Services Providers are concerned and where the GSM Network Operator provides a Single Sign-On service. Within the system, it is possible for a trusted authority to reveal the identity of the user if he or she is suspected of illegal activities. The system combines the GSM security features with the use of a digital signature to protect user privacy.
