A robust and composable device-independent protocol for oblivious transfer using (fully) untrusted quantum devices in the bounded storage model
Rishabh Batra, Sayantan Chakraborty, Rahul Jain +1
We present a robust and composable device-independent (DI) quantum protocol between two parties for oblivious transfer (OT) using Magic Square devices in the bounded storage model…

A Framework for Ruling Out Quantum Speedups
Thomas Huffstutler, Upendra Kapshikar, David Miloschewsky +1
We study when partial Boolean functions can (and cannot) exhibit superpolynomial quantum query speedups, and develop a general framework for ruling out such speedups via two comple…

Towards Universal Quantum Tamper Detection
Anne Broadbent, Upendra Kapshikar, Denis Rochette
Tamper-resilient cryptography studies how to protect data against adversaries who can physically manipulate codewords before they are decoded. The notion of tamper detection codes…
