Initial State Privacy of Nonlinear Systems on Riemannian Manifolds
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

Unboxing ARX-Based White-Box Ciphers: Chosen-Plaintext Computation Analysis and Its Applications
Transactions on Cryptographic Hardware and Embedded SystemsIt has been proven that the white-box ciphers with small encodings will be vulnerable to algebraic and computation attacks. By leveraging the large encodings, the self-equivalence and implicit implementations are proposed for ARXbased white-box ciphers.

Algebraic Side-Channel Attack on Twofish.
J. Internet Serv. Inf. Secur., 2017 While algebraic side-channel attack (ASCA) has been successful in breaking simple cryptographic algorithms, it has never been done on larger or more complex algorithms such as Twofish. Compared to other algorithms that ASCA has been used on, Twofish is more difficult to attack due to the key-dependent S-boxes as well as the complex key scheduling.

Algebraic attacks on certain stream ciphers. [PDF]
, 2006 To encrypt data streams of arbitrary lengths, keystream generators are used in modern cryptography which transform a secret initial value, called the key, into a long sequence of seemingly random bits.

White light emitting molecular logic gates
Smart Molecules, EarlyView.White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Fast Algebraic Immunity of
IEEE Access, 2019 Boolean functions should possess high fast algebraic immunity (FAI) when it is used in stream ciphers in order to stand up to fast algebraic attacks. However, in previous research, the FAI of Boolean functions was usually calculated by computer.

Low-Memory Algebraic Attacks on Round-Reduced LowMC [PDF]
, 2021 With the proposal of Picnic3, it has become interesting to investigate the security of LowMC with a full S-box layer. To significantly improve the efficiency of the Picnic signature, the designers of Picnic3 recommended to use the 4-round LowMC as the ...

steel research international, EarlyView.Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.
