Error correcting codes and collision-resistant hashing [PDF]

Proceedings of the 1999 IEEE Information Theory and Communications Workshop (Cat. No. 99EX253), 2003
This extended abstract proposes a general construction for fast and secure nm-bit collision-resistant compression functions based on error-correcting codes and m-bit collision-resistant compression functions. This leads to simple and practical hash function constructions based on block ciphers such as DES and AES. Under reasonable assumptions about the

On Distributional Collision Resistant Hashing

2018
Collision resistant hashing is a fundamental concept that is the basis for many of the important cryptographic primitives and protocols. Collision resistant hashing is a family of compressing functions such that no efficient adversary can find any collision given a random function in the family.

Atom Collision-Induced Resistivity of Carbon Nanotubes

Science, 2005
We report the observation of unusually strong and systematic changes in the electron transport in metallic single-walled carbon nanotubes that are undergoing collisions with inert gas atoms or small molecules. At fixed gas temperature and pressure, changes in the resistance and thermopower of thin films are observed that scale as roughly

Collision Resistant Hashing for Paranoids: Dealing with Multiple Collisions

2018
A collision resistant hash (CRH) function is one that compresses its input, yet it is hard to find a collision, i.e. a \(x_1 \ne x_2\) s.t. \(h(x_1) = h(x_2)\). Collision resistant hash functions are one of the more useful cryptographic primitives both in theory and in practice and two prominent applications are in signature schemes and succinct zero ...
