Security of Key-Alternating Ciphers: Quantum Lower Bounds and Quantum Walk Attacks
Chen Bai, Mehdi Esmaili, Atul Mantri
We study the quantum security of key-alternating ciphers (KAC), a natural multi-round generalization of the Even--Mansour construction. KAC abstracts the round structure of practic…

Lattice-Based Quantum Advantage from Rotated Measurements
Yusuf Alnawakhtha, Atul Mantri, Carl A. Miller +1
Trapdoor claw-free functions (TCFs) are immensely valuable in cryptographic interactions between a classical client and a quantum server. Typically, a protocol has the quantum serv…
