Abstract:

This paper describes C-EDR, a scalable protocol for pseudonymous communications. C-EDR is based on EDR and Crowds, which provides strong anonymity and high efficiency by encrypting the receiver＇s address and random forward- ing. It reduces the overhead of the message head,and advances the scalability y. This paper also analyzes the anonymity provid- ed by C-EDR.

Key words: anonymous, pseudonymous eommunieation, EDR, Crowds
