We discuss the widely increasing range of applications of a cryptographic technique called multi-party computation. For many decades, this was perceived to be of purely theoretical interest, but now it has started to find application in a number of use cases. We highlight in this paper a number of these, ranging from securing small high-value items such as cryptographic keys, through to securing an entire database. We might think of a protocol as a set of instructions in a distributed computer program. That program consists of a series of interactive rigid steps which are known by all participating parties beforehand.

Secret sharing scheme SSS has been extensively studied since SSSs are important not only for secure data storage but also as the fundamental building block for many cryptographic protocols such as multiparty computation MPC. This enables one to secretly-share data compactly and extend secretly-shared data to MPC if needed. Unable to display preview. Download preview PDF. Skip to main content.

Secure Multiparty Computation and Secret Sharing

Secure multi-party computation also known as secure computation , multi-party computation MPC , or privacy-preserving computation is a subfield of cryptography with the goal of creating methods for parties to jointly compute a function over their inputs while keeping those inputs private. Unlike traditional cryptographic tasks, where cryptography assures security and integrity of communication or storage and the adversary is outside the system of participants an eavesdropper on the sender and receiver , the cryptography in this model protects participants' privacy from each other. Note that traditionally, cryptography was about concealing content, while this new type of computation and protocol is about concealing partial information about data while computing with the data from many sources, and correctly producing outputs. Special purpose protocols for specific tasks started in the late s. The two party case was followed by a generalization to the multi-party by Goldreich, Micali and Wigderson. The computation is based on secret sharing of all the inputs and zero-knowledge proofs for a potentially malicious case, where the majority of honest players in the malicious adversary case assure that bad behavior is detected and the computation continues with the dishonest person eliminated or his input revealed. This work suggested the very basic general scheme to be followed by essentially all future multi-party protocols for secure computing.

The quantum secure multiparty computation is one of the important properties of secure quantum communication. To make this protocol secure and realistic, we combine both the classical and quantum phenomena. Compared to other protocols our proposed protocol is more cost-effective, realistic, and secure.

An efficient simulation for quantum secure multiparty computation

The purpose of the attack is to learn the private information of non-colluding, honest players or to cause the computation to be incorrect. As a result, there are two important requirements of a multiparty computation protocol: privacy and correctness. Below is a list of key and a list of supporting publications found in the computer science literature. If you have an additional citation you deem essential to this collection, please let us know.

Кипя от злости, тот нырнул в стремительно уплотняющуюся толпу. Он должен настичь Дэвида Беккера. Халохот отчаянно пытался протиснуться к концу улочки, но внезапно почувствовал, что тонет в этом море человеческих тел. Со всех сторон его окружали мужчины в пиджаках и галстуках и женщины в черных платьях и кружевных накидках на опущенных головах.

Он тихонько толкнул дверь, и та отворилась. Беккер с трудом сдержал крик ужаса. Меган сидела на унитазе с закатившимися вверх глазами.

 Твое сокровище в беде, коммандер, - пробормотал.  - Не веришь моей интуиции. Так я тебе докажу.

Она была слишком возбуждена, чтобы ответить. Испания. Так вот почему Дэвид отложил поездку в Стоун-Мэнор. - Сегодня утром я послал за ним машину.
