QIris: Quantum Implementation of Rainbow Table Attacks

TL;DR

QIris tackles accelerating rainbow-table-based hash attacks by integrating Grover’s quantum search into the classical rainbow-table workflow. The authors implement a hybrid quantum-classical pipeline, using MD5-based rainbow tables with four reductions and a bucketization scheme, and validate it in simulation with a 4-qubit prototype. They show that the quantum search reduces the lookup from $O(N)$ to $O(\sqrt{N})$ within buckets, followed by classical verification to recover the plaintext. The work discusses hardware limitations, uses a simplified hashing scheme, and outlines concrete future extensions such as other hash functions and quantum salt, providing a roadmap for quantum-assisted cryptanalysis.

Abstract

This paper explores the use of Grover's Algorithm in the classical rainbow table, uncovering the potential of integrating quantum computing techniques with conventional cryptographic methods to develop a Quantum Rainbow Table Proof-of-Concept. This leverages on Quantum concepts and algorithms which includes the principle of qubit superposition, entanglement and teleportation, coupled with Grover's Algorithm to enable a more efficient search through the rainbow table. The paper also details on the hardware constraints and the work around to produce better results in the implementation stages. Through this work we develop a working prototype of quantum rainbow table and demonstrate how quantum computing could significantly improve the speed of cyber tools such as password crackers and thus impact the cyber security landscape.
