Anonymous communication essentially involves two difficulties; 1) How does the sender send a message anonymously? 2) How does the receiver send a reply to the anonymous sender? In this paper, we propose an anonymous communication method named Rivulet that overcomes both of the difficulties by using group communication. Moreover, anonymous communication holds two dilemmas; 1) Strong anonymity or good performance? 2) Protect the privacy or promote the crime? Rivulet provides a solution for the former dilemma. The latter one is hard and important problem for all privacy protection schemes, therefore, we have to keep discussing this dilemma.
