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 generating a set of PQC encryption attributes for encrypting the data based on the set of data attributes, the risk profile data structure, and the PQC cryptographic performance information. Subsequently, the example method includes encrypting the data based on the set of PQC encryption attributes.
