Dynamic cryptographic hash functions [PDF]
, 2007 This dissertation introduces a new type of cryptographic hash function, the dynamic cryptographic hash function. Dynamic cryptographic hash functions differ from traditional hash functions because they require a second parameter, the security parameter ...

A Cryptographic Hash Function from Markoff Triples
IACR Cryptol. ePrint Arch., 2021 Cryptographic hash functions from expander graphs were proposed by Charles, Goren, and Lauter in [CGL] based on the hardness of finding paths in the graph. In this paper, we propose a new candidate for a hash function based on the hardness of finding paths in the graph of Markoff triples modulo p.

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 Secure and Robust Image Hashing Scheme Using Gaussian Pyramids
Entropy, 2019 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 ...

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications
Advanced Intelligent Systems, EarlyView.To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...

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
