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.

Abstract: Various implementations relate to controller in a system, including: a device connected to a network; and a secure sub-system connected to the device via a first wired connection, the secure sub-system configured to: establish a trusted channel with a user certificate authority (CA) via a provisioning device; receive application parameters from user CA; provision a timestamp or secure time server information based upon the timestamp or secure time server information received from the user CA; create a device identity for the device; and terminate the trusted channel after provisioning the timestamp or secure time server information and creating the device identity for the device.
