Dynamic Undeniable Certified Email with Denial of Service Prevention
Abstract:
Dynamic Undeniable Certified Email with Denial of Service Prevention is an email
system which employs the fair exchange protocol. A sender would obtain messages
receipts after the intended receivers have received the sent message. The fair exchange
protocol provides that either both parties have the exchanged infonnation or none of them
do. All existing approaches to fair certified email achieve the fair exchange property
between a single sender and a receiver only. But they do not offer the fair exchange
between all senders and a receiver. Also, they do not prevent denial of service attack by
malicious senders. So, a malicious receiver can deny receiving messages from some
senders but do receive messages from other senders. Also, a malicious sender can flood
messages to a receiver so that the receiver is unable to process messages sent by
legitimate senders. We propose a new certified email protocol which provides the fair
exchange for all senders, called the undeniable fairness, and denial of service prevention.
