Oblivious Transfer Is Symmetric
Authors: Stefan Wolf, Jürg WullschlegerAbstract:
We show that oblivious transfer of bits from A to B can be
obtained from a single instance of the same primitive from B to A.
Our reduction is perfect and shows that oblivious transfer is in fact
a symmetric functionality. This solves an open problem posed by
Crépeau and Sántha in 1991.
