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.

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.

An efficient simulation for quantum secure multiparty computation

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.

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.

The quantum secure multiparty computation is one of the important properties of secure quantum communication.

Joseph I. Choi, Kevin R. When two or more parties need to compute a common result while safeguarding their sensitive inputs, they use secure multiparty computation SMC techniques such as garbled circuits. The traditional enabler of SMC is cryptography, but the significant number of cryptographic operations required results in these techniques being impractical for most real-time, online computations. Trusted execution environments TEEs provide hardware-enforced isolation of code and data in use, making them promising candidates for making SMC more tractable. This paper revisits the history of improvements to SMC over the years and considers the possibility of coupling trusted hardware with SMC.

 Это так важно? - полувопросительно произнес Джабба. - Очень важно, - сказал Смит.  - Если бы Танкадо подозревал некий подвох, он инстинктивно стал бы искать глазами убийцу. Как вы можете убедиться, этого не произошло. На экране Танкадо рухнул на колени, по-прежнему прижимая руку к груди и так ни разу и не подняв глаз. Он был совсем один и умирал естественной смертью. - Странно, - удивленно заметил Смит.

Мы идем ко дну. ГЛАВА 120 Шеф отдела обеспечения системной безопасности, тучный мужчина весом за центнер, стоял неподвижно, заложив руки за голову. Он не мог поверить, что дожил до подобной катастрофы. Он отдал распоряжение вырубить электропитание, но это все равно произойдет на двадцать минут позже, чем следует. Акулы со скоростными модемами успеют скачать чудовищные объемы секретной информации через открывшееся окно.

К отчетам о секретных операциях. К зарубежной агентурной сети. Им станут известны имена и местонахождение всех лиц, проходящих по федеральной программе защиты свидетелей, коды запуска межконтинентальных ракет. Мы должны немедленно вырубить электроснабжение. Немедленно. Казалось, на директора его слова не произвели впечатления.
