Abstract: ABSTRACT SELECTION OF POST-QUANTUM CRYPTOGRAPHY (PQC) SCHEMES AND PQC LIBRARIES FOR CRYPTOGRAPHIC APPLICATIONS OF AN ENTERPRISE Recommending an optimal combination of PQC schemes, and the PQC libraries for replacing the classical cryptographic schemes of a cryptographic application is a challenging decision problem. Embodiments herein provide a method for selection of the PQC schemes and the PQC libraries for cryptographic applications. The method first generates one or more candidate PQC libraries, for each of the plurality of cryptographic applications based on a plurality of stringent requirement attributes and a plurality of non-stringent requirement attributes, using a plurality of first compatible PQC libraries, and a plurality of second compatible PQC libraries. Further a scheme-library pair of the one or more candidate PQC libraries is obtained, for each the plurality of classical cryptographic schemes based on a plurality of performance objective metrics. Then one or more final candidate PQC libraries obtained using the scheme-library pair which is recommended for the plurality of cryptographic applications of an enterprise. [
