Random oblivious transfer
WebbThe ICM features automatic block transfer and evic-tion, and has been at the base of the vast literature on cache-oblivious algorithms, i.e., algorithms which run efficiently independently of the cache parameters (i.e., cache size and cache line size). Most importantly, cache-oblivious algorithms attaining minimal miss rate Webbwants to make sure Bob gets exactly one book. This problem is called oblivious transfer. They need a protocol that reveals m i (and nothing else) to Bob, and reveals nothing at all to Alice. They use the following protocol that uses a group G of prime order qwith generator g2G: Alice sends a random v R G to Bob, Bob chooses Z q and sends u g v ...

Webb8 apr. 2024 · It features a comparative overview of the various Oblivious Transfer Extensions and an implementation of the most well known OT extension scheme, presented in the paper “Extending Oblivious Transfers Efficiently” by Yuval Ishai, Joe Kilian, Kobbi Nissim and Erez Petrank, written in Java, using the SCAPI interface.
Webbthat only makes a black-box use of any two-message oblivious transfer protocol, along with a random oracle. All previous reusable NISC proto-cols either made a non-black-box use of cryptographic primitives (Cachin et al.

In this paper, we propose a 1-out-of-2 random obliv-ious transfer protocol and extend it to a 1-out-of-k random oblivious transfer protocol based on the LWE assumption, quantum computation and measurement.
