However, the hardware itself is inert without a software intermediary to translate high-level application commands into low-level hardware signals. This intermediary is the Rockey200 driver. This paper analyzes the role of this driver, tracing the data path from the protected application, through the driver stack, to the physical hardware.
The software stack for the Rockey200 can be conceptualized in layers. The driver is responsible for bridging the gap between the vendor-specific API and the standard OS stack. rockey200 smart card driver
To understand the driver, one must first understand the hardware interface it manages. The Rockey200 is distinguished by its use of standard USB protocols rather than proprietary communication requiring custom controller drivers.
