An Improved Hash Function Based on the Tillich-Zémor Hash Function [PDF]
Mathematics Interdisciplinary Research, 2018 Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem.
