An Improved Certified E-Mail Protocol Based on Author Based Selective Receipt
Now-a-days, e-mail has become one of the most widely used communication medium. Because of its low cost characteristics and rapid delivery of messages, e-mail is increasingly used in place of ordinary mail. However, the e-mail service exposes users to several risks related to the lack of security during the message exchange. Furthermore, regular mail offers services which are usually not provided by e-mail, and which are of crucial importance for "Official" events. Certified e-mail tries to provide users with additional guarantees on the content and the delivery of the messages, making e-mail equivalent and in some cases more convenient than the ordinary paper-based mail service.
