Developing a New Collision-Resistant Hashing Algorithm

open access: yesMathematics, 2022
Today, cryptographic hash functions have numerous applications in different areas. At the same time, new collision attacks have been developed recently, making some widely used algorithms like SHA-1 vulnerable and unreliable.

The Resistance of Ship Web Girders in Collision and Grounding [PDF]

open access: goldMathematical Problems in Engineering, 2014
Ship web girders play an important role in ship structure performance during collision and grounding accidents. The behavior of web girders subjected to in‐plane concentrated load is investigated by numerical simulation and theoretical analysis in this paper.

Stam’s Collision Resistance Conjecture [PDF]

open access: bronze, 2010
At CRYPTO 2008 Stam [7] made the following conjecture: if an m+s-bit to s-bit compression function F makes r calls to a primitive f of n-bit input, then a collision for F can be obtained (with high probability) using r2(nr−m)/(r+1) queries to f. For example, a 2n-bit to n-bit compression function making two calls to a random function of n-bit input ...

A Formula That Generates Hash Collisions [PDF]

open access: yesarXiv, 2018
We present an explicit formula that produces hash collisions for the Merkle-Damg{\aa}rd construction. The formula works for arbitrary choice of message block and irrespective of the standardized constants used in hash functions, although some padding schemes may cause the formula to fail.

Research on low-speed collision performance of Collision resistance of different materials

open access: goldIOP Conference Series: Earth and Environmental Science, 2021
Abstract In order to explore the impact of lightweight materials and structures on the performance of anti-collision beams, this paper selects aluminum alloy and carbon fiber as the research objects, and analyzes the difference in low-speed impact performance of open and closed anti-collision beams for these two materials.

Stam’s Conjecture and Threshold Phenomena in Collision Resistance [PDF]

open access: bronze, 2012
At CRYPTO 2008 Stam [8] conjectured that if an $$m\!+\!s$$-bit to s-bit compression function F makes r calls to a primitive f of n-bit input, then a collision for F can be obtained with high probability using $$r2^{nr-m/r+1}$$ queries to f, which is sometimes less than the birthday bound.

Analysis of the Collision Resistance of RadioGatúnUsing Algebraic Techniques [PDF]

open access: bronze, 2009
In this paper, we present some preliminary results on the security of the RadioGatun hash function. RadioGatu has an internal state of 58 words, and is parameterized by the word size, from one to 64 bits. We mostly study the one-bit version of RadioGatun since according to the authors, attacks on this version also affect the reasonably-sized versions ...

Robustness and Collision-Resistance of PhotoDNA

open access: goldJournal of Cyber Security and Mobility
PhotoDNA is a widely utilized hash designed to counteract Child Sexual Abuse Material (CSAM). However, there has been a scarcity of detailed information regarding its performance. In this paper, we present a comprehensive analysis of its robustness and susceptibility to false positives, along with fundamental insights into its structure.
