Webb27 feb. 2024 · Elette Boyle, Geoffroy Couteau, Niv Gilboa, Yuval Ishai, Lisa Kohl, Peter Rindal, Peter Scholl ~ eprint/2024/706 ~ CCS’19 We consider the problem of securely generating useful instances of two-party correlations, such as many independent copies of a random oblivious transfer (OT) correlation, using a small amount of communication. Webb2.1. De nition of Oblivious Transfer. Oblivious transfer (OT) is a cryptographic primitive in which any two communication parties play the roles of a sender and a chooser. In the t-out-of-n oblivious transfer (OTn t), the sender has n messages for the chooser and allows the chooser to optionally obtain t messages among n messages. Based on most OT

Protocol. To create 1-out-of-N, we use log2(N) 1-out-of-2 oblivious transfers of random bits to create log2(N) random strings. Each secret is masked with one of these strings (by XOR) and the receiving party picks one after which the sender reveals all the masked secrets.

In cryptography, an oblivious transfer (OT) protocol is a type of protocol in which a sender transfers one of potentially many pieces of information to a receiver, but remains oblivious as to what piece (if any) has been transferred. The first form of oblivious transfer was introduced in 1981 by Michael O. Rabin. In … Visa mer In Rabin's oblivious transfer protocol, the sender generates an RSA public modulus N=pq where p and q are large prime numbers, and an exponent e relatively prime to λ(N) = (p − 1)(q − 1). The sender encrypts the … Visa mer k-n Oblivious transfer is a special case of generalized oblivious transfer, which was presented by Ishai and Kushilevitz.
