Abstract

Systems and methods for factory management of regional cryptographic algorithms in an Information Handling System (IHS) are described. In an embodiment, an IHS may include: a host processor; a security processor coupled to the host processor; and a memory coupled to the security processor, the memory having program instructions stored thereon that, upon execution, cause the security processor to: generate a Cryptographic Algorithm Identity (CAI) key pair comprising a CAI public key and a CAI private key; issue a CAI Certificate Signing Request (CSR) to a factory IHS, where the CAI CSR comprises the CAI public key; receive a signed CAI certificate from the factory IHS, where the signed CAI certificate is usable to activate a selected set of regional cryptographic algorithms among a superset of regional cryptographic algorithms stored, during manufacturing of the IHS, in a firmware of the security processor; and store the signed CAI certificate.
