Carmit Hazay's Efficient Secure Two-Party Protocols: Techniques and PDF

By Carmit Hazay

The authors current a accomplished research of effective protocols and strategies for safe two-party computation – either common buildings that may be used to safely compute any performance, and protocols for particular difficulties of curiosity. The e-book specializes in thoughts for developing effective protocols and proving them safe. moreover, the authors research diversified definitional paradigms and evaluate the potency of protocols completed below those diverse definitions.

The publication opens with a basic creation to safe computation after which provides definitions of protection for a couple of various adversary types and definitional paradigms. within the moment half, the ebook indicates how any performance could be securely computed in an effective approach within the presence of semi-honest, malicious and covert adversaries. those normal structures supply a foundation for knowing the feasibility of safe computation, and they're an outstanding advent to layout paradigms and facts thoughts for effective protocols. within the ultimate half, the publication offers particular structures of significance. The authors commence with an in-depth examine of sigma protocols and 0 wisdom, concentrating on safe computation, and so they then offer a finished examine of the basic oblivious move functionality. ranging from protocols that in achieving privateness in basic terms, they express hugely effective structures that in attaining defense within the presence of malicious adversaries for either a unmarried and a number of batch executions. Oblivious pseudorandom functionality overview is then provided as an instantaneous program of oblivious move. eventually, the e-book concludes with examples of high-level protocol difficulties that reveal how particular homes of an issue will be exploited to achieve excessive potency: securely computing the kth-ranked aspect, and safe database and textual content seek.

This ebook is vital for practitioners and researchers within the box of safe protocols, really people with a spotlight on potency, and for researchers within the region of privacy-preserving facts mining. This booklet is usually used as a textbook for a sophisticated direction on safe protocols.

This protocol is based on Yao’s protocol for the semi-honest case, and includes significant machinery for preventing the parties from cheating. The basic technique for achieving this is called cut-and-choose. Specifically, one of the main problems that arises when running Yao’s protocol with malicious adversaries is that the party who constructs the garbled circuit can construct it incorrectly (since it is encrypted, this cannot be detected). In order to prevent such behavior, we have the party construct many copies of the circuit and then ask it to open half of them.

Thus, it is not sufficient that the distributions differ. Rather, one needs to be able to detect cheating in any given execution. • The fact that the distributions differ does not necessarily imply that the honest parties have an efficient distinguisher. Furthermore, in order to guarantee that the honest parties detect the cheating, they would have to analyze all traffic during an execution. However, this analysis cannot be part of the protocol because then the distinguishers used by the honest parties would be known (and potentially bypassed).

Loosely speaking, we require that a party’s view in a protocol execution be simulatable given only its input and output. This then implies that the parties learn nothing from the protocol execution itself, as desired. Definition of security. We begin with the following notation: • Let f = (f1 , f2 ) be a probabilistic polynomial-time functionality and let π be a two-party protocol for computing f . , mit ), where w ∈ {x, y} (its value depending on the value of i), r i equals the contents of the ith party’s internal random tape, and mij represents the jth message that it received.
