Optimised Multi-Party Certified Email Protocols

Abstract

As a value-added service to deliver important data over the Internet with guaranteed receipt for each successful delivery, certified email has been discussed for years and a number of research papers appeared in the literature. But most of them deal with the two-party scenarios, i.e., there are only one sender and one recipient. In some ap- plications, however, the same certified message may need to be sent to a set of recipients. In this paper, we present two optimized multi-party certified email protocols. Both of them have three major features. (1) A sender could notify multiple recipients of the same information while only those recipients who acknowledged are able to get the information. (2) Both the sender and the recipients can end a protocol run at any time without breach of fairness. (3) The exchange protocols are optimized, each of which has only three steps, and the TTP will not be involved unless an exception (e.g., a network failure or a party's misbehavior) occurs.

Optimized multi‐party certified email protocols

Jianying Zhou, Jose Antonio Onieva, Javier López

Purpose As a value‐added service to deliver important data over the internet with guaranteed receipt for each successful delivery, certified email has been discussed for years and a number of research papers appeared in the literature. This paper aims to present two optimized multi‐party certified email protocols. Design/methodology/approach Reviews two existing email protocols and provides a modified version to overcome their security flaws and weaknesses. Extends the two‐party protocol to a multi‐party scenario. Findings Both of the protocols have three major features. A sender could notify multiple recipients of the same information while only those recipients who acknowledged are able to get the information. Both the sender and the recipients can end a protocol run at any time without breach of fairness. The exchange protocols are optimized, each of which has only three steps, and the trusted third party will not be involved unless an exception (e.g. a network failure or a party's misbehavior) occurs. Originality/value Provides a focus on a value‐added service – certified email.

Generic, Optimistic, and Efficient Schemes for Fair Certified Email Delivery

Guilin Wang, Feng Bao, Kenji Imamoto +1 more

Abstract. As a value-added service for standard email systems, a certified email scheme allows a sender to deliver a message to a receiver in a fair way in the sense that either the sender obtains a receipt from the receiver and the receiver accesses the content of the email simultaneously, or neither party gets the expected item. In this paper, we first point out some weaknesses in several existing schemes. Then, we present two generic optimistic certified email schemes with transparent TTP. Our schemes are not only fair, but also support timeliness in two flavors: one scheme supports weak timeliness but with stateless TTP, while the other guarantees (strong) timeliness though only supports weak stateless TTP. Technical discussion and comparison are provide to show that our schemes are both secure and efficient, compared with the-state-of-art in this field.

Fair Certified Email Protocol

Abdullah Mohammed Alaraj

In this paper, a new fair certified email protocol is proposed. The proposed protocol uses offline trusted third party (TTP) that will only be involved if a party misbehaves, otherwise the TTP is inactive. The protocol is based on the verifiable and recoverable encryption of keys. In this regard, the recipient of an email will be able to verify if the encrypted key used to encrypt the email is correct. The protocol comprises of only three messages in the exchange sub-protocol and three messages in the recovery sub-protocol. The proposed protocol is more efficient compared with related protocols.

An improved certified email protocol using an offline TTP

Ranadeep Mukherjee, Ambar Dutta

Certified email allows two parties to exchange a message while providing each party an evidence to prove the involvement of the other party in the exchange. This paper proposes a new certified email protocol which aims to improve an existing popular protocol. It does so by using an offline TTP and implementing “no author selective receipt”.

A New Protocol for Certified Mail Based on Off-line Conditional TTP

Shen Wei

Electronic mail delivery is one of the most important and desirable services, by which the intended recipient will get the mail if and only if the mail originator receives a valid and irrefutable proof of the receipt. The idea of conditional trusted third party has been developed on the basis of semi-trusted TTP and a suite of acceptable conditions is given. A new practical protocol for certified e-mail is presented, which can guarantee acceptable fair with interception of conditional TTP. More, the evidence in the new protocol is publicly verifiable without any restrictions on the type of signature and encryption algorithms.

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.
