Quantum oblivious transfer protocols based on EPR states
Abstract
Description
We describe efficient protocols for quantum oblivious transfer and for one-out-of-two quantum oblivious transfer. These protocols, which can be implemented with present technology, are secure against general attacks as long as the cheater can not store the bit for an arbitrarily long period of time.
The EPR states that Alice sends to Bob are no longer orthogonal. Thus the modified protocol is secure even if Bob has the technology to determine which state was sent to him. The new protocol is efficient, feasible with present technology, and is secure against general attacks as long as Bob can not store the bit for an arbitrarily long period of time
