Abstract: In an approach to secure firmware updating, a system comprises: one or more user devices, each of the one or more user devices having one or more firmware modules; one or more computing devices; a digital signature repository; and a z-engine circuitry. The z-engine circuitry is configured to: receive firmware for a particular user device of the one or more user devices; receive a non-repeating input data; retrieve a hardware digital profile of the particular user device from the digital signature repository; process the non-repeating input data with the hardware digital profile to generate a unique result; perform a hash operation on the unique result to generate an encryption key; encrypt the firmware for the particular user device with the encryption key; and send the encrypted firmware to the particular user device.

Abstract: An accessory mounting plate for a modular mounting system is described. The accessory mounting plate allows screwless coupling with a mounting receptacle, and may be configured to support a variety of different accessories. In one example, an accessory mounting plate includes a main body, a screwless attachment aperture, and a dovetail structure. The screwless attachment aperture is configured to enable the main body to be screwlessly mounted to a mounting receptacle. The dovetail structure is configured to enable the main body to fictively engage the mounting receptacle.
