curl-collisions's Introduction

Curl Collisions

This project provides an efficient implementation of Heilman et al.'s collision attack on IOTA's now-deprecated hash function, Curl. It can be used to generate novel collisions in the hash function in minutes to hours depending on hardware. Please see our report for a detailed coverage of the methodology behind its implementation.

Usage

To generate collisions using this project, clone the repository locally and build with make. Start the program with ./collide -t NUM_THREADS where NUM_THREADS is the suitable number of threads for your machine.

curl-collisions's Issues

Please clarify difference(s) in implementation

I see that your implementation (in c) differs from that found here

Am I correct in my reading that you have shown your implementation of the curl function(s) to be vulnerable. Not the implementation referenced above.
