Instruction sequence expressions for the secure hash algorithm SHA-256
, 2013 The secure hash function SHA-256 is a function on bit strings. This means that its restriction to the bit strings of any given length can be computed by a finite instruction sequence that contains only instructions to set and get the content of Boolean registers, forward jump instructions, and a termination instruction.

Journal of Computational Chemistry, Volume 44, Issue 7, Page 843-856, March 15, 2023., 2023 Abstract A class of adamantane‐like molecular materials attracts attention because they exhibit an extreme non‐linear optical response and emit a broad white‐light spectrum after illumination with a continuous‐wave infrared laser source. According to recent studies, not only the nature of the cluster molecules, but also the macroscopic structure of the

Numerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023 Abstract Considering the space‐time adaptive method for parabolic evolution equations we introduced in Stevenson et al., this work discusses an implementation of the method in which every step is of linear complexity. Exploiting the tensor‐product structure of the space‐time cylinder, the method allows for a family of trial spaces given as spans of ...

An Improved Fast and Secure Hash Algorithm [PDF]
Journal of Information Processing Systems, 2012 Abstract —Recently, a fast and secure hash function SFHA – 256 has been proposed and claimed as more secure and as having a better performance than the SHA – 256. In this paper an improved version of SFHA – 256 is proposed and analyzed using two parameters, namely the avalanche effect and uniform deviation. The experimental results and further analysis

Semantic-Aware Adversarial Training for Reliable Deep Hashing Retrieval [PDF]
IEEE Transactions on Information Forensics and Security, vol. 18,
pp. 4681-4694, 2023, 2023 Deep hashing has been intensively studied and successfully applied in large-scale image retrieval systems due to its efficiency and effectiveness. Recent studies have recognized that the existence of adversarial examples poses a security threat to deep hashing models, that is, adversarial vulnerability. Notably, it is challenging to efficiently distill
