However, the paper, and the 35 passes, are now obsolete, as they were for old hard drive technology, as even the author readily ...

Data are written from the host to the device in 8bit/10bit format. On the level of the link layer the data are converted back to 8bit /byte format and then sent to the cache (either DRAM or SRAM). If the controller supports encryption (most of them do) the data are then ...

For proper security, graphic cards must be treated like all other sorts of hardware which have access to RAM: they must come under the umbrella of the MMU and the kernel-controlled scheduler, so that simultaneously executing tasks cannot impact each other, and may interact only through communication channels carefully managed by the kernel.
