The Efficiency and Security of Pseudonymous Digital Signature for Modern e-Services

This paper presents a cryptanalysis of Pseudonymous Digital Signature (PDS) described in. PDS proposed with respect to Pseudonymous Identification Scheme Intended to generate pseudonyms by trusted third party (usually the pseudonymity service provider) for registered users and organizations that provides on - line services. The results show that the PDS very fast and highly secure with a comparison to RSA signature. Furthermore PDS offers a powerful mechanism to overcome the drawbacks that a pseudonymous credentials suffering to enable secure and flexible modern e-services.
