On the Collision Resistance of RIPEMD-160 [PDF]
, 2006 In this article, the RIPEMD-160 hash function is studied in detail. To analyze the hash function, we have extended existing approaches and used recent results in cryptanalysis. While RIPEMD and RIPEMD-128 reduced to 3 rounds are vulnerable to the attack, it is not feasible for RIPEMD-160.

Collision Resistance of the JH Hash Function [PDF]
IEEE Transactions on Information Theory, 2011 In this paper, we analyze collision resistance of the JH hash function in the ideal primitive model. The JH hash function is one of the five SHA-3 candidates accepted for the final round of evaluation. The JH hash function uses a mode of operation based on a permutation, while its security has been elusive even in the random permutation model.

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

Collision Resistance from Multi-collision Resistance [PDF]
Journal of Cryptology, 2022 AbstractCollision-resistant hash functions ($$\textsf{CRH}$$ CRH ) are a fundamental and ubiquitous cryptographic primitive. Several recent works have studied a relaxation of $$\textsf{CRH}$$ CRH called t-way multi-collision-resistant hash functions ($$t\text {-}\textsf{MCRH}$$

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

Electron-hole collision limited resistance of gapped graphene [PDF]
Physical Review BCollisions between electrons and holes can dominate the carrier scattering in clean graphene samples in the vicinity of charge neutrality point. While electron-hole limited resistance in pristine gapless graphene is well-studied, its evolution with induction of band gap $E_g$ is less explored.

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

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