Crooked Indifferentiability of the Feistel Construction
The Feistel construction is a fundamental technique for building pseudorandom permutations and block ciphers. This paper shows that a simple adaptation of the construction is resistant, even to algorithm substitution attacks -- that is, adversarial subversion -- of the component round functions.

Verified Indifferentiable Hashing into Elliptic Curves [PDF]
Journal of Computer Security, 2012 Many cryptographic systems based on elliptic curves are proven secure in the Random Oracle Model, assuming there exist probabilistic functions that map elements in some domain (e.g. bitstrings) onto uniformly and independently distributed points in a curve.

Symbolic Synthesis of Indifferentiability Attacks
Proceedings of the 2022 ACM on Asia Conference on Computer and Communications Security, 2022 We propose automated methods for synthesising attacks against indifferentiability, a powerful simulation-based notion of security commonly used to reason about symmetric-key constructions. Our methods are inspired from symbolic cryptography which is popular to reason about, e.g., cryptographic protocols.

Freshwater Biology, Volume 68, Issue 7, Page 1279-1292, July 2023., 2023 Abstract Coastal wetlands are naturally subjected to salinity, which is expected to increase through global climate changes. Most species will be affected by these changes, leading to major consequences for community structure and ecosystem functioning.

Quantum Lazy Sampling and Game-Playing Proofs for Quantum Indifferentiability [PDF]
, 2021 Game-playing proofs constitute a powerful framework for non-quantum cryptographic security arguments, most notably applied in the context of indifferentiability. An essential ingredient in such proofs is lazy sampling of random primitives.

Resource-Restricted Indifferentiability [PDF]
, 2013 A major general paradigm in cryptography is the following argument: Whatever an adversary could do in the real world, it could just as well do in the ideal world. The standard interpretation of “just as well” is that the translation from the real to the ideal world, usually called a simulator, is achieved by a probabilistic polynomial-time algorithm ...

Parkinson's disease fluid biomarkers for differential diagnosis of atypical parkinsonian syndromes
Clinical and Translational Discovery, Volume 3, Issue 1, February 2023., 2023 Parkinson's disease (PD) and atypical parkinsonian syndromes (APS) are challenging to differentiate. Traditional biomarkers such as cerebrospinal fluid (CSF) alpha‐synuclein, Aβ42, and tau cannot distinguish PD and APS patients with confidence. CSF protein misfolding cyclic amplification, real‐time quaking‐induced conversion, and neurofilament light ...

Electrochemical Science Advances, Volume 3, Issue 1, February 2023., 2023 The following study establishes a link between the various possibilities of CBD cluster size and fractal dimension that may eventualize during the mixing process of slurry preparation to the resulting microstructural properties and hence to the performance of Lithium‐Ion Batteries.

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Progress management is an important scheme of construction management. In practical affairs, many unknown factors may lead to potential project delays and make the schedule risky. To address this issue, this paper proposes a data‐driven construction progress evaluation method that employs a probabilistic reliability analysis with BIM to effectively ...

Topological Appearance of Event Horizon: What Is the Topology of the Event Horizon That We Can See? [PDF]
, 1997 The topology of the event horizon (TOEH) is usually believed to be a sphere. Nevertheless, some numerical simulations of gravitational collapse with a toroidal event horizon or the collision of event horizons are reported.
