Abstract: Techniques and apparatuses are described that implement localization and health monitoring. With the use of multiple backscatter tags, a reader can be implemented with a single antenna and have a relatively small footprint compared to other systems that utilize antenna arrays or multiple readers. Also, the backscatter tags can be implemented as passive devices and located at fixed positions. In this way, a single power source can be provided at the reader, and target angular resolutions can be realized without the additional mechanical complexities associated with other moving systems. Additionally, the backscatter tags can be implemented using relatively low-cost commercial off-the-shelf hardware. As such, performance of the reader can be readily customized with the purchase of additional backscatter tags.

Abstract: This document discloses aspects of secure chip-wide communication. In some aspects, a host of a system generates integrity metadata for a command payload issued to a destination over an interconnect of the system. The integrity metadata can be generated based on respective values of bits that form the command payload, such as plaintext data bits. The destination validates the integrity of the command payload based on the integrity metadata before consuming the command payload. In some cases, the destination stores the integrity metadata with data of the command payload, which may be returned to the host along the data when requested. By so doing, the host and destinations of the system can use the integrity metadata to implement secure-chip wide communication, which may prevent fault injection attacks on the command payloads or response data during transit or at temporal storage locations within the system.
