What Are We Learning About the Research‐Practice Gap From HRD Scholars and HRD Scholar‐Practitioners?

Human Resource Development Quarterly, EarlyView.
ABSTRACT The research‐practice gap (the gap) in HRD remains a significant challenge, hindering the application of academic research to practice and the integration of workplace challenges into research efforts. It is critical for HRD research to address the gap to develop evidence‐based solutions for learning and organizational performance. The purpose

Chosen-ciphertext security from subset sum [PDF]

, 2015
We construct a public-key encryption (PKE) scheme whose security is polynomial-time equivalent to the hardness of the Subset Sum problem. Our scheme achieves the standard notion of indistinguishability against chosen-ciphertext attacks (IND-CCA) and can

Large‐Scale Distribution of Physical Data Using DNA‐of‐Things Technology in Newspaper Printing

Small, EarlyView.
DNA‐of‐things technology enables stable data storage in large‐scale newspaper printing, with successful retrieval of 37 kB of digital data from a single ink dot containing approximately 14 femtograms of DNA. ABSTRACT DNA represents a promising solution for high‐density and long‐term data storage. In this study, we explore the scalability and robustness

A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm

CAAI Transactions on Intelligence Technology, EarlyView.
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

CP‐ABE with outsourced decryption and directionally hidden policy

Security and Communication Networks, 2016
AbstractCiphertext‐policy attribute‐based encryption (CP‐ABE) is a novel cryptographic primitive for access controlling. However, the existing CP‐ABE schemes are very inefficient as the decryptions involve many expensive pairing operations. Another drawback is that the access policy itself may disclose some privacies of the users.
