ABSTRACT:
The present invention discloses systems and methods for communicating with a storage device configured to store signed program files, the method including the steps of: generating, by a program process, a respective command number associated with a process command; issuing, by the program process, the process command with the respective command number to the storage device; and according to the respective command number, verifying, by the storage device, whether the process command originated from a trusted program process launched from the program files stored in the storage device. Preferably, the step of verifying includes: generating, by the storage device, a respective initial command number associated with a requested program file; and attaching, by the storage device, the respective initial command number to a copy of the requested program file.
