TY - JOUR ID - TI - A Proposed Secure Protocol for E-Mail System Based on Authentication and Hash Function AU - Muna Mohammed Al-Nayar PY - 2011 VL - 29 IS - 16 SP - 3291 EP - 3301 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - Internet has opened new channel of communication enabling an e-mail to be sent to a relative thousands of kilometers away. This medium of communication opens doors for virtually free mass e-mailing, reaching out to hundreds of thousands users around the globe within seconds, so e-mail becomes the most popular form of communication today. E-mail systems have suffered from increasing attacking problem that threatens the validity and integrity of communication. Many differentapproaches for fighting this attack have been proposed, ranging from various sender authentication protocols to encrypt the message itself. This paper demonstrates a promising protocol. The proposed protocol ensures the authentication and integrity of the data and avoids the problem of key distribution or breaking by using multiplerandom keys generated automatically during communication session.
