Digital signatures over HMAC entangled chains
Engineering Science and Technology, an International Journal, 2022 In this work we present a new digital signature method based on hash chains and the hash message authentication code (HMAC). Unlike Blockchain technology, our approach establishes that the database of transactions is distributed among users, so each one ...

Theoretical Bitcoin Attacks with less than Half of the Computational Power (draft) [PDF]
, 2013 A widespread security claim of the Bitcoin system, presented in the original Bitcoin white-paper, states that the security of the system is guaranteed as long as there is no attacker in possession of half or more of the total computational power used to ...

Fast Verification of Hash Chains [PDF]
, 2004 A hash chain is a sequence of hash values x i = hash(x i − 1) for some initial secret value x 0. It allows to reveal the final value x n and to gradually disclose the pre-images x n − 1, x n − 2, ... whenever necessary. The correctness of a given value x i can then be verified by re-computing the chain and comparing the result to x n .

Advanced Intelligent Discovery, EarlyView.This study introduces a tree‐based machine learning approach to accelerate USP8 inhibitor discovery. The best‐performing model identified 100 high‐confidence repurposable compounds, half already approved or in clinical trials, and uncovered novel scaffolds not previously studied. These findings offer a solid foundation for rapid experimental follow‐up,

Securing Generative Artificial Intelligence with Parallel Magnetic Tunnel Junction True Randomness
Advanced Intelligent Systems, EarlyView.True random numbers can protect generative artificial intelligence (GAI) models from attacks. A highly parallel, spin‐transfer torque magnetic tunnel junction‐based system is demonstrated that generates high‐quality, energy‐efficient random numbers.

Civil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized
