Lower Bounds for Oblivious Transfer Reductions
We prove the first general and non-trivial lower bound for the number of times a 1-out-of-n Oblivious Transfer of strings of length should be invoked so as to obtain, by an inform...

New Monotones and Lower Bounds in Unconditional Two-Party Computation
Since bit and string oblivious transfer and commitment, two primitives of paramount importance in secure two- and multi-party computation, cannot be realized in an unconditionally ...

On the Efficiency of Classical and Quantum Oblivious Transfer Reductions
Due to its universality oblivious transfer (OT) is a primitive of great importance in secure multi-party computation. OT is impossible to implement from scratch in an unconditional...

Lower bounds for Quantum Oblivious Transfer
Oblivious transfer is a fundamental primitive in cryptography. While perfect information theoretic security is impossible, quantum oblivious transfer protocols can limit the disho...

On the (Im)possibility of Basing Oblivious Transfer and Bit Commitment on Weakened Security Assumptions
We consider the problem of basing Oblivious Transfer (OT) and Bit Commitment (BC), with information theoretic security, on seemingly weaker primitives. We introduce a general model...
