Abstract
An approach is provided for distributing a root key to a hardware security module (HSM) of an HSM cluster. A signed first command is transmitted to a source HSM to create a master key. A fingerprint of the master key is received in a response signed by the source HSM using a module signing key hardcoded into the source HSM at manufacturing time. A second command is transmitted to a first HSM to generate an importer key pair. A request is transmitted to the source HSM to create and export a wrapped master key. The master key wrapped with a transport key is received. The wrapped master key is transmitted to the first HSM. The master key is activated in the first HSM.
