Abstract

Systems, apparatuses, methods, and computer program products are disclosed for post-quantum cryptography (PQC). An example method includes monitoring an enveloped data structure comprising a data envelope and data encrypted based on a first set of PQC encryption attributes. The example method further includes generating an electronic indication of a change in the enveloped data structure. The example method further includes retrieving PQC cryptographic performance information associated with a set of PQC cryptographic techniques. The example method further includes generating a second set of PQC encryption attributes for encrypting the data based on the change in the enveloped data structure and the PQC cryptographic performance information. Subsequently, the example method includes encrypting the data based on the second set of PQC encryption attributes.
