Abstract:Quantum computers, especially those with over 10,000 qubits, pose a potential threat to current public key cryptography systems like RSA and ECC due to Shor’s algorithms. Grover’s search algorithm is another quantum algorithm that could significantly impact current cryptography, offering a quantum advantage in searching unsorted data. Therefore, with the advancement of quantum computers, it is crucial to analyze potential quantum threats.
While many works focus on Grover’s attacks in symmetric key cryptography, there has been no research on the practical implementation of the quantum approach for lattice-based cryptography. Currently, only theoretical analyses involve the application of Grover’s search to various Sieve algorithms.
In this work, for the first time, we present a quantum NV Sieve implementation to solve SVP, posing a threat to lattice-based cryptography. Additionally, we implement the extended version of the quantum NV Sieve (i.e., the dimension and rank of the lattice vector). Our extended implementation could be instrumental in extending the upper limit of SVP (currently, determining the upper limit of SVP is a vital factor). Lastly, we estimate the quantum resources required for each specific implementation and the application of Grover’s search.
In conclusion, our research lays the groundwork for the quantum NV Sieve to challenge lattice-based cryptography. In the future, we aim to conduct various experiments concerning the extended implementation and Grover’s search.
