We propose SeCReT to ameliorate this problem. is a framework that builds secure channel between the REE and TEE by enabling processes use session keys in regarded as unsafe region. provides key requestor process only when requestor’s code control flow integrity are verified. To prevent from being exposed an attacker who already compromised kernel, flushes memory every time processor switches into kernel mode. In paper, we present design implementation of show how it protects REE. Our...
Since the first demonstration of a production quality three-dimensional (3D) stacked-word-line NAND Flash memory [1], 3b/cell 3D has seen areal density increases more than 50% per year due to aggressive development 3D-wordline-stacking technology. This trend been consistent for last three consecutive years [2-4], however storage market still requires higher diverse digital applications.
