A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm
Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key

Spatiotemporal chaotic one-way Hash function construction based on coupled tent maps
A novel coupled tent maps-based spatiotemporal chaotic cryptographic Hash function was proposed.Compared with the discrete tent map,the coupled discrete tent spatiotemporal chaotic maps have longer computer-realization-period,nearly uniform distribution ...

ABSTRACT In recent years, the widespread application of deep reinforcement learning (DRL) in autonomous systems has highlighted the importance of achieving high sample efficiency under sparse reward conditions. To improve sample efficiency in sparse reward environments, this paper proposes a reinforcement learning framework built upon the Soft Actor ...

Cryptographic Hash Functions: Theory and Practice [PDF]
Cryptographic hash functions are an essential building block for security applications. Until 2005, the amount of theoretical research and cryptanalysis invested in this topic was rather limited. From the hundred designs published before 2005, about 80% was cryptanalyzed; this includes widely used hash functions such as MD4 and MD5.

Abstract In many environmental problems, emissions are hard to monitor and abatement costs are privately known. We study how efficient abatement nevertheless can be induced through market‐like arrangements that condition transfers on verifiable abatement rather than on measured emissions.

A Secure and Robust Image Hashing Scheme Using Gaussian Pyramids
Image hash is an alternative to cryptographic hash functions for checking integrity of digital images. Compared to cryptographic hash functions, an image hash or a Perceptual Hash Function (PHF) is resilient to content preserving distortions and ...

In this large real‐world propensity‐matched analysis, tirzepatide demonstrated superior reductions in mortality, hospitalizations, and cardiorenal outcomes versus dulaglutide in HFpEF patients, with a favorable safety profile. ABSTRACT Background No direct head‐to‐head trials compare tirzepatide and dulaglutide in heart failure with preserved ejection ...
