Robust Combiners and Universal Constructions for Quantum Cryptography [PDF]
arXiv, 2023 A robust combiner combines many candidates for a cryptographic primitive and generates a new candidate for the same primitive. Its correctness and security hold as long as one of the original candidates satisfies correctness and security. A universal construction is a closely related notion to a robust combiner. A universal construction for a primitive

Remarks on the Cryptographic Primitive of Attribute-based Encryption [PDF]
, 2014 Attribute-based encryption (ABE) which allows users to encrypt and decrypt messages based on user attributes is a type of one-to-many encryption. Unlike the conventional one-to-one encryption which has no intention to exclude any partners of the intended

Physically Unclonable Function Utilizing Stochastic Indirect Exchange Interaction
Small Structures, EarlyView.A physically unclonable function (PUF) utilizes manufacturing variations to create secret keys. This study proposes a spin–orbit torque PUF model based on the Ruderman–Kittel–Kasuya–Yosida interaction. It features near‐ideal properties that can operate under zero magnetic field and varying temperatures.

Variable Bit Permutations: Linear Characteristics and Pure VBP-Based Cipher [PDF]
Computer Science Journal of Moldova, 2005 This paper describes linear characteristics of the variable bit permutations (VBP) that are used in the form of the data-dependent permutations. This primitive suites well to the design of fast cheap-hardware-oriented ciphers. Because of the existence of

One-time memory from isolated Majorana islands
New Journal of Physics, 2022 A one-time memory (OTM) stores two bits such that either bit can be retrieved, but not both. One-time memories have been shown to allow for secure classical and quantum computations.

Towards Automated Augmentation and Instrumentation of Legacy Cryptographic Executables: Extended Version [PDF]
arXiv, 2020 Implementation flaws in cryptographic libraries, design flaws in underlying cryptographic primitives, and weaknesses in protocols using both, can all lead to exploitable vulnerabilities in software. Manually fixing such issues is challenging and resource consuming, especially when maintaining legacy software that contains broken or outdated ...
