Xiang Li

Published Jan 1, 2006• 2 citations
OpenAlex

Abstract

The non-repudiation and fairness of sender and receiver are essential in secure data transport protocol, it has been usually implemented by non- repudiation protocol used during data transmission. In this paper,a new fair non-repudiation and fairness protocol is presented based on the correction of CMP1 protocol which has some flaws. It has been verified satisfying non-repudiation and fairness by advanced Kailar logic, it can be abroad applied in E-mail and E-contract etc.

A fair non-repudiation security protocol with off-line TTP

Xi Wang, Xiangming Wen, Ye Liu +2 more

A fair non-repudiation security protocol can provide non-repudiation proof for two parts of the exchange at the same time, or both get nothing. But many protocols performed weak in logical analysis. In this paper, a group of new protocols(with 3 sub-protocols) with off-line The Third Party(TTP) are presented. We analysis them with a new Kailar logic analytical method. Finally, the proposed protocols are proved to satisfy the fairness, non-repudiation and efficiency from the theory. And they propose some protections for the networks which have merely physical securities such as Internet, and provide some realistic reference values to the establishment of security mobile ad-hoc networks.

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.

A Fair Accountability Protocol and Its Security Properties Analysis

Li Chen, Huaiqiang Li

Accountability and fairness are very important properties of electronic commerce security protocols. Some protocols are found that cannot achieve their desired security goals. In order to remedy the flaws of the CMP1 protocol, the paper proposes a new fair accountability protocol by adopting cryptographic hash function operation and introducing ftp transmission method. The proposed protocol is verified to satisfy accountability and fairness by utilizing the improved Kailar logic. The performance analysis of the proposed protocol shows that it is better in confidentiality and usability than the CMP1 protocol. It can be widely used in electronic commerce applications, such as E-mail and digital contract signing, and so on.

A Hybrid Cryptosystem-Based Non-Repudiation Protocol and Its Formal Analysis

Li Yan

A non-repudiation cryptographic protocol based on hybrid cryptosystem is proposed and it is a more perfect protocol.It can realize the true fairness and non-repudiation of both parties even the channels are unreliable and insecure.Usually the protocol only needs three interactions of participants and the transferring data keep confidential for others except for the sender and the receiver,whose transactions are protected.The Trusted Third Party(TTP) performs evidences verification,generation and publication and its bottleneck problem is solved completely.Finally,we give its formal analysis and prove the protocol's fairness,correctness and security.
