Improving the Security of Quantum Protocols via Commit-and-Open
We consider two-party quantum protocols starting with a transmission of some random BB84 qubits followed by classical messages. We show a general “compiler” improving the secur...

On Unconditionally Secure Distributed Oblivious Transfer
This paper is about the Oblivious Transfer in the distributed model proposed by M. Naor and B. Pinkas. In this setting a Sender has n secrets and a Receiver is interested in one o...

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...

The Cost of Cache-Oblivious Searching
This paper gives tight bounds on the cost of cache-oblivious searching. The paper shows that no cache-oblivious search structure can guarantee a search performance of fewer than l...

Lower Bounds and Impossibility Results for Concurrent Self Composition
In the setting of concurrent self composition, a single protocol is executed many times concurrently by a single set of parties. In this paper, we prove lower bounds and impossibi...
