Abstract: A data processing system includes support for sub-page granular memory tags. The data processing system comprises at least one core, a memory controller responsive to the core, random access memory (RAM) responsive to the memory controller, and a memory protection module in the memory controller. The memory protection module enables the memory controller to use a memory tag value supplied as part of a memory address to protect data stored at a location that is based on a location value supplied as another part of the memory address. The data processing system also comprises an operating system (OS) which, when executed in the data processing system, manages swapping a page of data out of the RAM to non-volatile storage (NVS) by using a memory tag map (MTM) to apply memory tags to respective subpages within the page being swapped out. Other embodiments are described and claimed.

Abstract: Computing platform security methods and apparatus are disclosed. An example apparatus includes a security application to configure a security task, the security task to detect a malicious element on a computing platform, the computing platform including a central processing unit and a graphics processing unit; and an offloader to determine whether the central processing unit or the graphics processing unit is to execute the security task; and when the graphics processing unit is to execute the security task, offload the security task to the graphics processing unit for execution.

Abstract: Systems and method to provide secure storage are disclosed. An example method includes establishing a secure tunnel between a storage device and an agent, provide a command from the agent to the storage device via the secure tunnel, access first data at the storage device in response to the command, and identify a modification to data stored on the storage device by comparing the first data to second data, wherein the comparison is done using the storage device.
Abstract translation: 公开了提供安全存储的系统和方法。 示例性方法包括在存储设备和代理之间建立安全通道，经由安全隧道从代理向存储设备提供命令，响应于命令访问存储设备处的第一数据，并且识别对数据的修改 通过将第一数据与第二数据进行比较来存储在存储装置上，其中使用存储装置进行比较。
