A Novel Multi-party Key Exchange Protocol
2018A key exchange protocols are generally used in order to exchange a cryptographic session key, such that no one except the communicating party must be able to deduce the keys lifetime. In this paper we propose a protocol which can be used for multi-party key exchange amongst the entities with less number of iterations, and also the same protocol can be ...

Network-Hiding Communication and Applications to Multi-party Protocols
2016As distributed networks are heavily used in modern applications, new security challenges emerge. In a multi-party computation in short, MPC protocol over an incomplete network, such a challenge is to hide, to the extent possible, the topology of the underlying communication network.

Secure Multi-party Comparison Protocol and Application
2017The problem of information comparison is always an important field of SMC. In order to effectively solve the fully equal problem of multi-data for all information, a secure two-party multi-data comparison protocol for equality (STMC) is proposed with the aid of the NTRU encryption.

A Multi-Party Protocol for Privacy-Preserving Range Queries
2014Privacy-preserving query processing (PPQP) techniques are increasingly important in collaborative scenarios, where users need to execute queries on large amount of data shared among different parties who do not want to disclose private data to the others.

An Efficient and Secure Protocol for Multi-party Key Establishment
The Computer Journal, 2001Summary: A multi-party key establishment protocol based on the difficulty of calculating discrete logarithms in a finite field is proposed with the following features. It requires a constant number (independent of the number of participants) of rounds. All messages have the same constant size.

An Unconditionally Secure Protocol for Multi-Party Set Intersection
2007Existing protocols for private set intersection are based on homomorphic public-key encryption and the technique of representing sets as polynomials in the cryptographic model. Based on the ideas of these protocols and the two-dimensional verifiable secret sharing scheme, we propose a protocol for private set intersection in the information-theoretic ...

Attacking an Asynchronous Multi-party Contract Signing Protocol
2005Contract signing is a fundamental service in doing business. The Internet has facilitated the electronic commerce, and it is necessary to find appropriate mechanisms for contract signing in the digital world. From a designing point of view, digital contract signing is a particular form of electronic fair exchange.

A Realistic Protocol for Multi-party Certified Electronic Mail
2002In some cases, users need to notify the same information to multiple recipients, with the requirement that these recipients have to send an acknowledgement of receipt. In this paper we present an optimistic protocol for multi-party certified electronic mail.
