Blockchain Technology and the Circular Economy Transition: Associations With Company Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT The adoption of circular economy (CE) practices in the private sector has received increasing academic and managerial attention, although the implementation of such practices continues to face significant barriers. Among Industry 4.0 technologies, blockchain has been identified as a potential factor associated with the CE transition.

Anti-disassembly using Cryptographic Hash Functions [PDF]

Journal in Computer Virology, 2006
Computer viruses sometimes employ coding techniques intended to make analysis difficult for anti-virus researchers; techniques to obscure code to impair static code analysis are called anti-disassembly techniques. We present a new method of anti-disassembly based on cryptographic hash functions which is portable, hard to analyze, and can be used to ...

A new design paradigm for provably secure keyless hash function with subsets and two variables polynomial function

Journal of King Saud University: Computer and Information Sciences, 2022
Provably secure keyless hash function uses Random Oracle (RO) or Sponge principles for the design and construction of security-centric hash algorithms. It capitalizes the aforesaid principles to produce outcomes like MD2, MD5, SHA-160, SHA-224/256, SHA ...

Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

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

Development of a New Post-Quantum Digital Signature Algorithm: Syrga-1

Computers
The distinguishing feature of hash-based algorithms is their high confidence in security. When designing electronic signature schemes, proofs of security reduction to certain properties of cryptographic hash functions are used.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Keyed Parallel Hash Algorithm Based on Multiple Chaotic Maps (KPHA-MCM)

IEEE Access, 2021
Hash functions are considered as the core of cryptography, which are the basic technique used for data security. Cryptographic hash functions also can be used to achieve the integrity of large data such as the data stored in a hard disk and set of ...

A trapdoor one-way function for verifiable secret sharing

High-Confidence Computing, 2022
This paper proposes a (t,n)–threshold verifiable secret sharing scheme with changeable parameters based on a trapdoor one-way function. This scheme consists of a generation phase, a distribution phase, an encoding phase and a reconstruction phase.
