Summary: 
When two parties connect via a possibly unreliable network, ensuring fairness becomes a serious problem. To solve this problem, a lot of Certified E-mail systems are proposed. However, user's privacy including confidentiality and anonymity is not considered in almost all of these systems. In this paper, we propose two private message board systems using an electronic notice board to solve Certified mail problem.
