Revisiting Variable Output Length XOR Pseudorandom Function
IACR Transactions on Symmetric Cryptology, 2018 Let σ be some positive integer and C ⊆ {(i, j) : 1 ≤ i < j ≤ σ}. The theory behind finding a lower bound on the number of distinct blocks P1, . . . , Pσ ∈ {0, 1}n satisfying a set of linear equations {Pi ⊕Pj = ci,j : (i, j) ∈ C} for some ci,j ∈ {0, 1}n ...

Exploring Crypto-Physical Dark Matter and Learning with Physical Rounding
Transactions on Cryptographic Hardware and Embedded Systems, 2020 State-of-the-art re-keying schemes can be viewed as a tradeoff between efficient but heuristic solutions based on binary field multiplications, that are only secure if implemented with a sufficient amount of noise, and formal but more expensive solutions

Revisiting structure graphs: Applications to CBC-MAC and EMAC
Journal of Mathematical Cryptology, 2016 In [2], Bellare, Pietrzak and Rogaway proved an O(ℓq2/2n)${O(\ell q^{2}/2^{n})}$ bound for the PRF (pseudorandom function) security of the CBC-MAC based on an n-bit random permutation Π, provided ...

A Note on Quantum-Secure PRPs [PDF]
QuantumWe show how to construct pseudorandom permutations (PRPs) that remain secure even if the adversary can query the permutation, both in the forward and reverse directions, on a quantum superposition of inputs.

Farfalle: parallel permutation-based cryptography
IACR Transactions on Symmetric Cryptology, 2017 In this paper, we introduce Farfalle, a new permutation-based construction for building a pseudorandom function (PRF). The PRF takes as input a key and a sequence of arbitrary-length data strings, and returns an arbitrary-length output.

Privacy protection key distribution protocol for edge computing
网络与信息安全学报, 2021 Aiming at the privacy protection problem in the multi-application scenarios of edge computing, two policy-based key distribution protocols were proposed.The proposed protocols are based on the concept of constrained pseudo-random functions to achieve ...

Pseudorandom Noise Forced Oscillation Technique to Assess Lung Function in Prematurely Born Children
Children, 2022 The forced oscillation technique (FOT) is a non-volitional assessment that is used during tidal breathing. A variant of FOT uses a pseudorandom noise (PRN) signal which we postulated might have utility in assessing lung function in prematurely born ...

Pseudorandom Function from Learning Burnside Problem
MathematicsWe present three progressively refined pseudorandom function (PRF) constructions based on the learning Burnside homomorphisms with noise (Bn-LHN) assumption. A key challenge in this approach is error management, which we address by extracting errors from

Optimal pseudorandom sequence selection for online c-VEP based BCI control applications.
PLoS ONE, 2017 BackgroundIn a c-VEP BCI setting, test subjects can have highly varying performances when different pseudorandom sequences are applied as stimulus, and ideally, multiple codes should be supported.
