Abstract
A method in a security device that provides a security service to a host includes receiving a security command from an application program running on the host. The security command is executed by accessing a Non-Volatile Memory (NVM) device external to the security device transparently to the application program via a dedicated device driver, which runs on the host and mediates between the NVM device and the security device.
