The Secure Device Update (SDU) library is a software library to assist with device firmware or software updates. The goal of this project is to make updating your device firmware in a secure way a minimal burden on device software or firmware developers.
The platform is available with full source code for all necessary firmware and support utilities, avoiding any vendor lock-in concerns. Support utilities are licensed BSD and the firmware portion will be available soon in a source release with GPLv2 or commercial licensing options. Please contact me at [email protected] for early access.
For more about the background and motivation for this project, see the release announcement.
The SDU library is written in C with a design that it can be easily ported to support specific device platforms. Please refer to each platform page for instructions specific to each platform.
Please contact me at [email protected] if you are interested in porting to a new device platform.
