Connected devices require a secure point-to-point channel to ensure that there is no possibility of exposing important data for the integrity of an embedded system. This is especially true when we talk about over-the-air (OTA) software updates, where the new firmware has a long way to go before reaching its destination and being installed by our bootloader. In this publication, we will explore a simple method to encrypt the firmware using the AES algorithm, using open-source libraries in Python.
Although the extended reality of the metaverse may seem like it belongs in a mystifying, somewhat distant future, we’re already living in it. It’s built on the integration of augmented reality (AR) and virtual reality (VR) in the physical world. Industry leaders are exploring how these emerging technologies can enrich existing business processes. What they’ve honed in on is that the metaverse has remarkable potential to transform the future of digital learning and work.
