Abstract: Examples relate to in-memory attack prevention. The examples disclosed herein enable obtaining, in response to a first boot command, a first encryption key generated based on a randomization process. The examples further enable determining whether first information of a page table indicates that a memory page is intended to be secure, the page table storing mapping between a virtual address of the memory page and a physical address of the memory page. In response to determining that the first information indicates that the memory page is intended to be secure, the examples further enable determining whether second information of the page table indicates that the memory page is encrypted. In response to determining that the second information indicates that the memory page is not encrypted, the examples further enable encrypting the memory page in a physical memory using the first encryption key.

Abstract: An apparatus operates to provide default services or functionality. The apparatus authenticates replaceable resources by determining whether the replaceable resources originate from a desired source. The apparatus provides an auxiliary service or functionality in addition to the default services or functionality when each of the replaceable resources originates from the desired source, and precludes the auxiliary service or functionality when any of the replaceable resources do not originate from the desired source.

Abstract: Information relating to a user input to edit a portion of an image is received, where the image is divided into a plurality of tiles. In response to the received information, at least one further tile in a representation of the edit is created. A data structure including entries that link the plurality of tiles and the at least one further tile is created. The at least one further tile with the plurality of tiles are combined to produce an output page that includes the image with the edit applied to the image.

Abstract: Examples of the present disclosure provide apparatuses and methods for error code calculation. The apparatus can include an array of memory cells that are coupled to sense lines. The apparatus can include a controller configured to control a sensing circuitry, that is coupled to the sense lines, to perform a number of operations without transferring data via an input/output (I/O) lines. The sensing circuitry can be controlled to calculate an error code for data stored in the array of memory cells and compare the error code with an initial error code for the data to determine whether the data has been modified.

Abstract: The present disclosure is related to encryption of executables in computational memory. Computational memory can traverse an operating system page table in the computational memory for a page marked as executable. In response to finding a page marked as executable, the computational memory can determine whether the page marked as executable has been encrypted. In response to determining that the page marked as executable is not encrypted, the computational memory can generate a key for the page marked as executable. The computational memory can encrypt the page marked as executable using the key.

Abstract: A printer includes an interface selector to generate a signal that indicates whether a stylus has been installed with a printer. An interface controller monitors the signal from the interface selector to detect if the stylus has been installed with the printer and generates a first printer interface if the stylus has been detected and generates a second printer interface if the stylus has not been detected.

Abstract: According to an example, data and instruction set encryption may include generating keys to encrypt data and instructions. The instructions may be executable by a CPU. The keys may be mapped to memory ranges of a PM including a flat address space. The flat address space of the PM may be partitioned according to the memory ranges. The keys and the memory ranges mapped to the keys may be stored in a keymap array. The data and the instructions may be encrypted based on the keys.
