摘要： Embodiments are directed to providing a secure address translation service. An embodiment of a system includes a memory for storage of data, an Input/Output Memory Management Unit (IOMMU) coupled to the memory via a host-to-device link the IOMMU to perform operations, comprising receiving an address translation request from a remote device via a host-to-device link, wherein the address translation request comprises a virtual address (VA), determining a physical address (PA) associated with the virtual address (VA), generating an encrypted physical address (EPA) using at least the physical address (PA) and a cryptographic key, and sending the encrypted physical address (EPA) to the remote device via the host-to-device link.

摘要： A data processing system includes technology to enable implicit integrity to be used for digital communications. That technology comprises a hardware processor and an implicit integrity engine (IIE) responsive to the processor. For instance, in response to the data processing system receiving a communication that contains a message, the IIE is to automatically analyze the communication to determine whether the message was sent with implicit integrity. If the message was sent with implicit integrity, the IIE is to automatically use a pattern matching algorithm to analyze entropy characteristics of a plaintext version of the message, and to automatically determine whether the message has low entropy, based on results of the pattern matching algorithm and a predetermined entropy threshold. If the message does not have low entropy, the IIE is to automatically determine that the message has been corrupted. Other embodiments are described and claimed.

An embodiment of a system includes a memory for storage of data, an Input/Output Memory Management Unit (IOMMU) coupled to the memory via a host-to-device link the IOMMU to perform operations, comprising receiving a memory access request from a remote device via a host-to-device link, wherein the memory access request comprises a host physical address (HPA) that identifies a physical address within the memory pertaining to the memory access request and a first message authentication code (MAC), generating a second message authentication code (MAC) using the host physical address received with the memory access request and a private key associated with the remote device, and performing at least one of allowing the memory access to proceed when the first MAC and the second MAC match and the HPA is not in an invalidation tracking table (ITT) maintained by the IOMMU; or blocking the memory operation when the first MAC and the second MAC do not match.

摘要： Specular light shadow removal is described for use in image de-noising. In one example a method includes placing a window on an image, determining a cumulative distribution function for the window, determining a destination histogram for the window, determining a cumulative distribution function for the destination histogram, replacing the intensity of a pixel with the smallest index for which the histogram distribution for the pixel is greater than the window distribution, repeating determining a cumulative distribution function, a destination histogram, and a cumulative distribution function and replacing the intensity for a plurality of windows of the image, and de-noising the image after repeating by applying a median filter to the image.

摘要： A flexible aes instruction set for a general purpose processor is provided. The instruction set includes instructions to perform a “one round” pass for aes encryption or decryption and also includes instructions to perform key generation. An immediate may be used to indicate round number and key size for key generation for 128/192/256 bit keys. The flexible aes instruction set enables full use of pipelining capabilities because it does not require tracking of implicit registers.

摘要： Logic may implement implicit integrity techniques to maintain integrity of data. Logic may perform operations on data stored in main memory, cache, flash, data storage, or any other memory. Logic may perform more than one pattern check to determine repetitions of entities within the data. Logic may determine entropy index values and/or Boolean values and/or may compare the results to threshold values to determine if a data unit is valid. Logic may merge a tag with the data unit without expanding the data unit to create an encoded data unit. Logic may decode and process the encoded data unit to determine the data unit and the tag. Logic may determine value histograms for two or more entities, determine a sum of repetitions of the two or more entities, and compare the sum to a threshold value. Logic may determine that a data unit is valid or is corrupted.

摘要： Embodiments of a system and method for detecting a palm of a hand using an image are generally described herein. A method for detecting a palm of a hand may include determining a plurality of cumulative distance values from pixels in a set of image pixels to pixels in a plurality of finger template matches, wherein the set of image pixels includes a set of image pixels on detected edges in the image. The method may include selecting a set of finger template matches from the plurality of finger template matches, corresponding to a set of smallest cumulative distance values from the plurality of cumulative distance values. The method may include refining the set of finger template matches to create refined finger templates, bundling refined finger templates to create a bundle of refined finger templates, and verifying that the bundle of refined finger templates includes a valid palm detection.
