Towards a Trust-Based Model for Administration of Mailing Lists

Today, e-mail is one of the most popular communication facilities. E-mail list service (ELS) is a useful facility for scientific, commercial and social user groups. The main concern about ELS is how to manage and control the access of different users. To secure ELS by using security protocols and encryption/decryption mechanisms as well as user authentication, the computational overhead of servers will increase considerably. In addition, these methods do not offer adequate mechanism for entrance and subscription of users. In this paper we propose a trust-based scheme for managing users and controlling their access, with a minimum overhead on server. This scheme also manages the behaviour of users dynamically and establishes a two way connection between them.
