An Efficient Two-Factor Authentication Scheme Based on the Merkle Tree
Sensors, 2020 The Time-based One-Time Password (TOTP) algorithm is commonly used for two-factor authentication. In this algorithm, a shared secret is used to derive a One-Time Password (OTP). However, in TOTP, the client and the server need to agree on a shared secret

Fair micropayment system based on hash chains
Tsinghua Science and Technology, 2005 Micropayment schemes usually do not provide fairness, which means that either the customer or the merchant, or both, can cheat each other and gain a financial advantage by misusing the protocols. This paper proposes an efficient hash chain-based micropayment scheme, which is an offline, prepaid scheme that supports simpler divisibility of digital coins.

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

Atomic and privacy-preserving cyclic cross-chain protocol based on chameleon hash function
Blockchain: Research and ApplicationsBlockchain-based digital assets have increasingly emerged in recent years, necessitating cross-chain swaps. Hash Time-Lock Contract (HTLC) is a widely used protocol for such swaps; however, simple hash time locks can allow attackers to analyze ...

Integrated Model of Image Protection Techniques
Journal of Imaging, 2017 We propose an integrated model of Block-Permutation-Based Encryption (BPBE) and Reversible Data Hiding (RDH). The BPBE scheme involves four processes for encryption, namely block scrambling, block-rotation/inversion, negative-positive transformation and ...

Secure spontaneous emergency access to personal health record [PDF]
, 2011 We propose a system which enables access to the user's Personal Health Record (PHR) in the event of emergency. The access typically occurs in an ad-hoc and spontaneous manner and the user is usually unconscious, hence rendering the unavailability of ...

Encrypted data inquiries using chained perfect hashing (CPH) [PDF]
AIP Conference Proceedings, 2017 Cryptography is the practice of transforming data to indecipherable by a third party, unless a particular piece of secret information is made available to them. Data encryption has been paid a great attention to protect data. As data sizes are growing, so does the need for efficient data search while being encrypted to protect it during transmission ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

From Expectations to Experience: A Comparison of Program Director Priorities to Resident Case Logs
The Laryngoscope, EarlyView.The present study identified 47 essential otolaryngology procedures via program director surveys and evaluated the extent of resident participation in these cases through ACGME case logs. Results revealed significant variability in surgical experience, with nearly half of these essential procedures being logged fewer than 10 times during residency ...
