In an oblivious transfer (OT) protocol, a Sender with messages M1, . . . , MN and a Receiver with indices 1, . . . , k [1, N] interact in such a way that at the end the Receiver ...
Oblivious transfer is one of the most important cryptographic primitives, both for theoretical and practical reasons and several protocols were proposed during the years. We provid...
We aim at constructing adaptive oblivious transfer protocols, enjoying fully simulatable security, from various well-known assumptions such as DDH, d-Linear, QR, DCR, and LWE. To t...
We construct efficient universally composable oblivious transfer protocols in the multi-party setting for honest majorities. Unlike previous proposals our protocols are designed in...
