Abstract
Various embodiments relate to a system for provisioning a cryptographic device, including: a memory; a processor coupled to the memory, wherein the processor is further configured to: determine a maximum PQC private key size, maximum PQC public key size, and maximum PQC updater size of a plurality of post quantum cryptography algorithms; provision memory in the cryptographic device to store a PQC-update non-PQC private key, a secret PQC-update non-PQC public key, PQC private key, PQC public key, and PQC updater based upon the determined maximum PQC private key size, maximum PQC public key size, and maximum updater size; and provision the cryptographic device with the PQC-update non-PQC private key, the secret PQC-update non-PQC public key, a non-PQC secret key, a non-PQC public key, and non-PQC algorithm code configured to carry out non-PQC cryptographic algorithms.
