Abstract
Session access to files in a file system mounted in a secure memory region in a secure memory device. In response to a request from an application to open a session for the file system to access the memory region, a secure command is sent to the memory device to install an access control key for the memory region. After storing a session key in a key repository, the application can call the operating system to access files in the file system. In response, the file system can generate access commands to be transmitted to the memory device. The session key stored in the key repository can be used to sign the access commands on behalf of the application. The memory device uses the access control key to validate the access commands signed using the session key prior to the execution of the access commands.
