On The Simplest Quantum-Secure Block Cipher
Gorjan Alagic, Joseph Carolan, Christian Majenz +1
Pseudorandom permutations are ubiquitous in theoretical and applied cryptography. PRPs that offer security even against adversaries making quantum queries are of increasing interes…
Differentially private quantum sensor networks
Daniel J. Spencer, Kaiyan Shi, Emil T. Khabiboulline +2
Quantum sensing is a promising technology capable of demonstrating clear advantage over comparable classical techniques for precise measurement. One application of quantum sensing…
The Sponge is Quantum Indifferentiable
Gorjan Alagic, Joseph Carolan, Christian Majenz +1
The sponge is a cryptographic construction that turns a public permutation into a hash function. When instantiated with the Keccak permutation, the sponge forms the NIST SHA-3 stan…
On the Two-sided Permutation Inversion Problem
Gorjan Alagic, Chen Bai, Alexander Poremba +1
In the permutation inversion problem, the task is to find the preimage of some challenge value, given oracle access to the permutation. This is a fundamental problem in query compl…
Post-Quantum Security of the Even-Mansour Cipher
Gorjan Alagic, Chen Bai, Jonathan Katz +1
The Even-Mansour cipher is a simple method for constructing a (keyed) pseudorandom permutation from a public random permutation~. It is secur…
Impossibility of Quantum Virtual Black-Box Obfuscation of Classical Circuits
Gorjan Alagic, Zvika Brakerski, Yfke Dulek +1
Virtual black-box obfuscation is a strong cryptographic primitive: it encrypts a circuit while maintaining its full input/output functionality. A remarkable result by Barak et al.…
