Key Projects

Exploring Function Inversion: From Fiat-Naor Algorithm to Rainbow Tables (DURF)

Research Project

June 2024 - October 2024

Conducted an in-depth analysis of the Fiat and Naor algorithm variant, focusing on the paper "Beating Brute Force for Compression Problems", introducing a k-regular constraint to the function f and demonstrating that the worst-case circuit size for inverting f could be reduced to 2³ⁿ/⁴ poly(s(n)).
Implemented code to invert subset sum hashes using Rainbow Tables based on the open-sourced RainbowCrack-NG library, achieving an average accuracy of 99.5%, higher than the results from MD5, but also with longer generating and cracking time, which aligned with theoretical expectations.

Decentralized Messaging App Development
