Abstract

Systems, apparatuses, methods, and computer program products are disclosed for post-quantum cryptography (PQC). An example method includes receiving data, a set of data attributes about the data, and a risk profile data structure indicative of a vulnerability of the data in a PQC data environment. The example method further includes retrieving PQC cryptographic performance information associated with a set of PQC cryptographic techniques. The PQC cryptographic performance information may comprise a set of PQC cryptographic performance attributes for each PQC cryptographic technique in the set of PQC cryptographic techniques. The example method further includes selecting a PQC encryption algorithm for encrypting the data based on the set of data attributes, the risk profile data structure, the PQC cryptographic performance information, and a PQC optimization machine learning model. Subsequently, the example method includes encrypting the data based on the selected PQC encryption algorithm.
