A New Certified E-Mail Protocol Based on Signcrytion

Published Jan 1, 2008• 1 citation

Abstract

A certified e-mail protocol is about fair exchange of a message m for its receipt. Fairness is the most important property in exchange. We modify existing W-B signcryption scheme so that it can be used by certified e-mail protocols,and based on the modified scheme we propose a new certified e-mail protocol. The protocol makes use of an off-line and transparent trusted third party only in exceptional circumstances,and has lower computation overhead and better efficiency comparing related protocol.

An Efficient Identity-Based Certified E-mail Protocol

Caifen Wang, Xiaodong Yang, Caihui Lan +1 more

Signcryption is to perform encryption and signature in a single logical step, and is more efficient than the sign-then-encryption scheme. However, most of the proposed signcryption approaches cannot be used directly by certified e-mail protocol. In this paper, we first develop an id-based signcryption method, which allows a trusted third party to compute a cipher text of a message together with other parties. Then based on the signcryption scheme we propose a new id-based certified e-mail protocol. The fairness, efficiency, and effectiveness of our protocol have been proved.

An ID-Based Certified E-mail Protocol Suitable for Wireless Mobile Environments

Caifen Wang, Caihui Lan, Shufen Niu +1 more

Certified e-mail protocol is a fair exchange of a message for a receipt between two potentially mistrusting parties over the network. A number of certified e-mail protocols have been studied in recent years. However, most of those protocols employ certificate-based cryptography and full trusted third party, which may not be suitable for wireless networks with limited resources such as power, computation and bandwidth. In this work, we propose an improved identity-based (or ID-based) signcryption & re-encryption scheme. Based on this scheme, we develop a novel certified e-mail protocol in the ID-based settings that employ an off-line semi-trusted third party (STTP) for wireless networks. By avoiding the complicated computation from the public key authentication in the certificate-based cryptography, the proposed scheme can simplify the management of the certification process and reduce communication cost in the system. Our detailed elaboration and analysis shows that the proposed approach is dynamic, lightweight and scalable.

Design and formal analysis of a new Fair Multi-Party Certified Mail Protocol

Yuexiang Gao, Daiyuan Peng, Lili Yan

Fair Multi-Party Certified Mail Protocol is a value service to deliver important data over internet with guaranteed receipt for each successful delivery. Therefore, the protocol needs to be Confidential, Non-repudiation and Fairness. This paper pointed out potential security concern for a current protocol, and also came out an offline third party fair multi-party certified Mail Protocol based on signcryption scheme. Through the analysis by Kailar logic, it is can be seen the protocol can achieve the non-repudiation, fairness. Furthermore, it has advantage of resisting the attacks as distort, replay and conspiracy.
