On the Security of a Multi-party Certified Email Protocol
, 2004 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.

Proceedings of the fifteenth annual ACM symposium on Theory of computing - STOC '83, 1983
Many different types of inter-process communication have been examined from a complexity point of view [SP, Y]. We study a new model, in which a collection of processes P0, ..., Pk−1 that share information about a set of integers {a0, ...,ak−1}, communicate to determine a 0-1 predicate of the numbers.

Adaptive Security of Multi-party Protocols, Revisited
2021The goal of secure multi-party computation (MPC) is to allow a set of parties to perform an arbitrary computation task, where the security guarantees depend on the set of parties that are corrupted. The more parties are corrupted, the less is guaranteed, and typically the guarantees are completely lost when the number of corrupted parties exceeds a ...

On the security of multi-party ping-pong protocols
24th Annual Symposium on Foundations of Computer Science (sfcs 1983), 1983We define a p-party ping-pong protocol and its security problem, along the lines of Dolev and Yao's definition for twoparty ping-pong protocol. In the case of two parties, it was assumed, with no loss of generality, that there exists a single saboteur in the net and the protocol was defined to be secure iff it was secure against the active ...

Privacy for multi-party protocols
1993We initiate information theoretic investigation of the amount of leaked information in multi-party protocols. It is shown that mutual information is a satisfactory measure of the amount of the leaked information. For more than two parties, we apply multi-terminal information theory and give a formulation of the leaked information.

A Multi-party Rational Exchange Protocol
2007In recent years, existing computing schemes and paradigms have evolved towards more flexible, ad-hoc scalable frameworks. Nowadays, exchanging interactions between entities often takes place in nonstructured environments where the number and nature of the different participants are unknown variables. In this context, traditional fair exchange protocols

On the Efficiency of Multi-party Contract Signing Protocols
2015This paper presents an efficiency study of fair exchange protocols for Multi-Party Contract Signing MPCS from their architecture point of view, an approach that has not been previously explored. A set of common topologies is presented and defined: ring, star sequential and mesh.
