A Universal Serial Bus (USB) compatible storage device is utilized as a security token for storage of cryptographic keys. A cryptographic subsystem of a processor accesses cryptographic keys in containers on the USB compatible storage device. Accessing includes storing and/or retrieving. The processor does not include an infrastructure dedicated to the USB compatible storage device. Cryptographic key storage is redirected from an in-processor container to the USB compatible storage device. No password or PIN is required to access the cryptographic keys, yet enhanced security is provided. Utilizing a USB compatible storage device for a cryptographic key container provides a convenient, portable, mechanism for carrying the cryptographic key, and additional security is provided via physical possession of the device. |
