The famous Fiat-Shamir transformation turns any public-coin three-round interactive proof, i.e., any so-called $$\Sigma {\text {-protocol}}$$, into a non-interactive proof in the random-oracle model. We study this transformation in the setting of a quantum adversary that in particular may query the random oracle in quantum superposition.

This work shows that for t-fold parallel repetitions of typical (k1, . . . , kμ)-special-sound protocols with t ≥ μ, there is an attack that results in a security loss of approximately 1 2 Q μ/μμ+t.

The first examples of natural cryptographic schemes that separate classical and quantum random oracle models are given, which construct digital signature and public key encryption schemes that are secure in the classical random oracles model but insecure in the quantumrandom oracle model assuming the quantum hardness of learning with error problem.

### SO-CCA Secure PKE in the Quantum Random Oracle Model or the Quantum Ideal Cipher Model

• Computer Science, Mathematics
IMACC
• 2019
It is shown that there exist PKE schemes which meet the standard security such as indistinguishability against chosen ciphertext attacks (IND-CCA security) but do not meet SO security against chosen Ciphertext attacks, so it is important to consider SO security in the multi-user setting.

This paper shows that if the authors start from a commit-and-open identification scheme, where the prover first commits to several strings and then as a second message opens a subset of them depending on the verifier's message, then the Fiat-Shamir transform is quantum secure, for a suitable choice of commitment scheme.

### Quantum Random Oracle Model with Auxiliary Input

The random oracle model (ROM) is an idealized model where hash functions are modeled as random functions that are only accessible as oracles and no work has dealt with the above two problems simultaneously.

### A non-PCP Approach to Succinct Quantum-Safe Zero-Knowledge

Today’s most compact zero-knowledge arguments are based on the hardness of the discrete logarithm problem and related classical assumptions, which, by exploiting extra algebraic structure, are a few orders of magnitude more compact in practice than the generic constructions.

### Post-quantum Security of Fiat-Shamir

The Fiat-Shamir construction is an efficient transformation in the random oracle model for creating non-interactive proof systems and signatures from sigma-protocols, but Ambainis, Rosmanis, and Unruh ruled out non-relativizing proofs under those conditions in the quantum setting.
