Quantum inspired factorization up to 100-bit RSA number in polynomial time (2410.16355v2)

Published 21 Oct 2024 in cs.CR and quant-ph

Abstract: Classical public-key cryptography standards rely on the Rivest-Shamir-Adleman (RSA) encryption protocol. The security of this protocol is based on the exponential computational complexity of the most efficient classical algorithms for factoring large semiprime numbers into their two prime components. Here, we attack RSA factorization building on Schnorr's mathematical framework where factorization translates into a combinatorial optimization problem. We solve the optimization task via tensor network methods, a quantum-inspired classical numerical technique. This tensor network Schnorr's sieving algorithm displays numerical evidence of a polynomial scaling of the resources with the bit-length of the semiprime. We factorize RSA numbers up to 100 bits encoding the optimization problem in quantum systems with up to 256 qubits. Only the high-order polynomial scaling of the required resources limits the factorization of larger numbers. Although these results do not currently undermine the security of the present communication infrastructure, they strongly highlight the urgency of implementing post-quantum cryptography or quantum key distribution.

Quantum Inspired Factorization of RSA Numbers Using Tensor Network Methods

The paper "Quantum Inspired Factorization up to 100-bit RSA Number in Polynomial Time" presents a novel approach to the factorization of RSA numbers by leveraging quantum-inspired methods. This research is a significant step in the exploration of computational techniques that bridge classical and quantum paradigms, aiming to address the challenging problem of integer factorization that underpins the security of modern cryptographic systems.

Overview of the Methodology

The authors build upon Schnorr’s mathematical framework, which translates the problem of RSA factorization into a combinatorial optimization problem. They employ tensor network methods, specifically focusing on a variant called Schnorr’s sieving algorithm. This approach maps the factorization problem onto quantum systems using up to 256 qubits, providing numerical evidence that suggests a polynomial scaling of the resources with respect to the bit-length of the semiprime numbers.

The research relies heavily on the concept of the Closest Vector Problem (CVP) as a lattice-based representation of the factorization challenge. The tensor network Schnorr’s sieving (TNSS) algorithm is a critical component that utilizes tensor networks to efficiently analyze and optimize the lattice points in order to identify valid prime factors of the given RSA number.

Numerical Results and Claims

The researchers successfully applied their method to factorize RSA numbers up to 100 bits in length, showcasing the algorithm's capacity to manage computational tasks involving large numbers. They identify and discuss the polynomial scaling of required resources as a function of the key bit-length. This accomplishment, while not currently a threat to RSA encryption used in practice, indicates that classical resources might suffice for polynomial-time factorization using TNSS methods, assuming further optimization and scaling of the approach.

Implications and Future Directions

The implications of this work are twofold. Practically, it underscores the necessity of advancing post-quantum cryptographic systems and quantum key distribution mechanisms to ensure the continued security of digital communications. Theoretically, it contributes to the understanding of how quantum-inspired methodologies can be harnessed to solve complex problems traditionally resistant to classical approaches.

Furthermore, the research invites speculation about future developments in artificial intelligence and computational methods that could augment current capabilities. Employing tensor networks, which are extensively used in quantum simulations, reveals the potential utility of quantum-inspired models in addressing NP-hard problems.

The paper calls for further exploration and scaling of the TNSS approach to potentially extend its applicability to larger RSA numbers, possibly encompassing those used in current industry standards. The computational techniques presented, combined with high-performance computing strategies and parallelization, suggest a potential pathway towards more efficient cryptographic factorization.

In conclusion, the efficacy and efficiency of the TNSS algorithm for factorization tasks propose exciting avenues for future research in the intersection of quantum computing, cryptography, and computational optimization, marking a substantive addition to the field.
