Theoretical Analysis and Software Implementation of a Quantum Encryption Proposal

Abstract

This paper analyzes a quantum substitute proposal for current public-key cryptographic systems based on factorization and discrete logarithm. Both its theoretical analysis and its practical implementation are described here. The implementation has been carried out from scratch using IBM Qiskit SDK, reformulating the entire protocol to compact it within a previous library of the authors. The obtained results are conclusive about the insecurity of the proposed scheme.
