Abstract
Disclosed are a system and a method for transferring with improved security root keys from a key provider system to a customer system via an information network that is other than secure. The key provider provides a secure module having a super-root key stored therein within the customer system. The super-root key is accessible internally to the module only by program code executable on a processor internal to the module, and only in response to a request from a corresponding module of the key provider system. The super-root key is only for use in decrypting encrypted root keys that are provided from the key provider system, which decrypted root keys are stored internally to the secure module.
