Improving firmware updates for Internet of Things devices – the IETF SUIT Hackathon in Berlin/Germany
Last updated about 13 hours ago, by Hannes Tschofenig. Arm Research, hackathon
IoT devices commonly require security patches and updates to protect against known vulnerabilities. In this blog post Hannes Tschofenig highlights a recently-launched standardization effort in the Internet Engineering Task Force (IETF): the “Software Updates group for Internet of Things (SUIT)” working group. The report shares experiences from a Hackathon in Berlin, where several working group members met to work on code for firmware updates.
Working Group Formation and IETF London Hackathon
The Internet Engineering Task Force (IETF) met in London from March 17th – 23rd for the first face-to-face meeting of the IETF Software Updates group for Internet of Things (SUIT). The SUIT working group is chartered to develop firmware update solutions that can be implemented into Internet of Things (IoT) devices, especially microcontrollers with limited RAM and flash memory, such as 10 KiB RAM and 100 KiB flash. The focus of the group is simple: since many IoT devices require software updates to fix security vulnerabilities, the group will develop and standardize a secure approach to these updates. For IoT devices, this software update often comes in the form of a monolithic block, where the entire codebase running on the device, i.e. the firmware, is replaced in one shot.[…]
