Implementation of Node Authentication for WSN Using Hash Chains
Procedia Computer Science, 2016 AbstractThis paper presents the design and implementation of a lightweight node authentication protocol which comprises of node registration, node authentication and key establishment phases. The solution leverages the low computational overheads associated with cryptographically secure one-way hash chains and Elliptical Curve Crytography (ECC) without

Multi-Dimensional Hash Chains and Application to Micropayment Schemes [PDF]
arXiv, 2005 One-way hash chains have been used in many micropayment schemes due to their simplicity and efficiency. In this paper we introduce the notion of multi-dimensional hash chains, which is a new generalization of traditional one-way hash chains. We show that this construction has storage-computational complexity of O(logN) per chain element, which is ...

Accounting &Finance, EarlyView.Abstract This study explores the practical impact of blockchain technology (BCT), which contrasts strongly with literature that has predominantly hypothesised BCT's potential to disrupt accounting practice. We interviewed 44 practitioners and academics with knowledge of BCT across 13 countries and industries.

StarZIP: Streaming Graph Compression Technique for Data Archiving
IEEE Access, 2019 The size of a streaming graph is possibly unbounded, and it is updated by a continuous sequence of edges over time. Due to numerous types of real-world interactions, the nature of edge arrival in a streaming graph is dynamic and holds different types of ...

Individual displacements in hashing with coalesced chains [PDF]
arXiv, 2005 We study the asymptotic distribution of the displacements in hashing with coalesced chains, for both late-insertion and early-insertion. Asymptotic formulas for means and variances follow. The method uses Poissonization and some stochastic calculus.

A Standalone FPGA-based Miner for Lyra2REv2 Cryptocurrencies [PDF]
, 2019 Lyra2REv2 is a hashing algorithm that consists of a chain of individual hashing algorithms, and it is used as a proof-of-work function in several cryptocurrencies. The most crucial and exotic hashing algorithm in the Lyra2REv2 chain is a specific instance of the general Lyra2 algorithm.

Andrology, EarlyView.Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Current application of blockchain technology in healthcare and its potential roles in Urology
BJU International, EarlyView.Objective To assess the current uses of blockchain technology in surgery and explore potential applications in urology. Methods A systematic literature review and critical appraisal was performed. The PubMed database was searched for all relevant papers published in English, between 2003 and 2023, on blockchain and surgery, and urology.

Fully Distributed Cooperative Spectrum Sensing for Cognitive Radio Networks [PDF]
, 2012 Cognitive radio networks (CRN) sense spectrum occupancy and manage themselves to operate in unused bands without disturbing licensed users. The detection capability of a radio system can be enhanced if the sensing process is performed jointly by a group ...
