Lower Bounds for Oblivious Data Structures
Riko Jacob, Kasper Green Larsen, Jesper Buus Nielsen
An oblivious data structure is a data structure where the memory access patterns reveals no information about the operations performed on it. Such data structures were introduced b…
A New Approach to Practical Active-Secure Two-Party Computation
Jesper Buus Nielsen, Peter Sebastian Nordholt, Claudio Orlandi +1
We propose a new approach to practical two-party computation secure against an active adversary. All prior practical protocols were based on Yao's garbled circuits. We use an OT-ba…
Superposition Attacks on Cryptographic Protocols
Ivan Damgaard, Jakob Funder, Jesper Buus Nielsen +1
Attacks on classical cryptographic protocols are usually modeled by allowing an adversary to ask queries from an oracle. Security is then defined by requiring that as long as the q…
Fully Simulatable Quantum-Secure Coin-Flipping and Applications
Carolin Lunemann, Jesper Buus Nielsen
We propose a coin-flip protocol which yields a string of strong, random coins and is fully simulatable against poly-sized quantum adversaries on both sides. It can be implemented w…
Secure two-party quantum evaluation of unitaries against specious adversaries
Frédéric Dupuis, Jesper Buus Nielsen, Louis Salvail
We describe how any two-party quantum computation, specified by a unitary which simultaneously acts on the registers of both parties, can be privately implemented against a quantum…
