Abstract

In the recent years, the design and analysis of the security of e-commerce protocol has become a hot scheme. The confidentiality and fairness are important properties to measure the security of the e-commerce. It's also the important prerequisite of the successful protocol. Confidentiality and fairness are the basic properties of the secure e-commerce protocol. But the certified e-mail protocol as one of the e-commerce protocol can't satisfy these properties. This paper points out some drawbacks of teh CMP protocol, and analyses the protocol and makes improvements. The improved CMP protocol satisfies the confidentiality and fairness.

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.

Improvement and Formal Analysis of a Fair Multi-party Certified Mail Protocol

Peng Dai-yuan

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,and meets non-repudiation,fairness,exclusion and timeliness.This paper pointed out potential security concern for a current protocol,and improved the protocol based on signcryption scheme.The analysis by Kailar logic shows that the protocol can achieve the non-repudiation,fairness.Furthermore,it has advantage of resisting the attacks such as distort,replay and conspiracy.

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.

Analysis and Improvement of a Mutually Undeniable Cryptographic Protocol

Yanping Li

Non-repudiation service is the foundation of security on which important data and sensitive news are conveyed on the Internet in e-commerce. Non-repudiation protocol is a special network protocol which provides non-repudiation service. Because of the importance of non-repudiation to electronic commerce activities and the fact that non-repudiation protocol is relatively few, this paper adopts the modern cryptographic algorithms and techniques and designs a mutually undeniable cryptographic protocol. Analyses show that the improved protocol avoids the trusted third party being the bottleneck problem, and also realizes the confidentiality of transferring data, and the fairness and non-repudiation of the sender and the receiver.

New Certified E-mail Protocol

Gengli Chen

A certified E-mail protocol is about fair exchange of a message m for its receipt.Fairness is the most important property in exchange.It modifies existing convertible authenticated encryption scheme so that it can be used by certified E-mail protocols,and based on the scheme,a new certified E-mail protocol is proposed to guarantee privacy and low computation overhead.
