Oblivious transfer refers to a cryptographic protocol in which a sender possesses a set of data and a receiver queries the sender for a particular member of that set in such a way that the sender does not learn which member the receiver requests. In other words, the sender is oblivious of what she ...

Why use a 1-2 Oblivious Transfer instead of a 1 out of n Oblivious Transfer?
When initiating an oblivious transfer, why would someone use a 1-2 oblivious transfer rather than going for an 1 out of n oblivious transfer? Perhaps a slight time overhead for the extra message ...

Randomized Oblivious Transfer
If we define Oblivious Transfer as following:
Alice inputs $(x_0,x_1) \in F^2$, where $F$ is a field, and Bob inputs $b\in\{0,1\}$, then Alice gets a dummy output(for which she knows nothing about b), ...

Is it possible to build an unfair noisy channel from 1 out of 2 oblivious transfer [closed]
For a fair channel, sender sends a bit b and receiver gets it with probability 1/2 and gets b's flipped value with probability 1/2. It is trivial to build a fair noisy channel from 1 out of 2 ...
