Indistinguishability Lifting for Keyed Oracles, Compressed Ideal Cipher, and More Applications
Ritam Bhaumik, Yu-Hsuan Huang
Cryptographic security proofs often involve an adversary interacting with a larger, keyed oracle that consists of (potentially exponentially) many independent instances of a smalle…
Adaptive versus Static Multi-oracle Algorithms, and Quantum Security of a Split-key PRF
Jelle Don, Serge Fehr, Yu-Hsuan Huang
In the first part of the paper, we show a generic compiler that transforms any oracle algorithm that can query multiple oracles adaptively, i.e., can decide on which oracle to quer…
Isogeny-based Group Signatures and Accountable Ring Signatures in QROM
Kai-Min Chung, Yao-Ching Hsieh, Mi-Ying Huang +3
We present the first provably secure isogeny-based group signature (GS) and accountable ring signature (ARS) in the quantum random oracle model (QROM). We do so via introducing and…
On the Compressed-Oracle Technique, and Post-Quantum Security of Proofs of Sequential Work
Kai-Min Chung, Serge Fehr, Yu-Hsuan Huang +1
We revisit the so-called compressed oracle technique, introduced by Zhandry for analyzing quantum algorithms in the quantum random oracle model (QROM). To start off with, we offer…
