Using OP-TEE to Authenticate IoT Devices
Deploying IoT devices into the field poses the question of how to authenticate these devices against your own services. While software authentication of bootloader, kernel, and filesystems ensures that only trusted software is run on the device, preventing extraction of authentication data from the device requires the use of a Trusted Platform Module (TPM) or equivalent mechanisms. This blog post introduces OP-TEE and PKCS#11 as a software alternative.

"FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. In 2021, they will gather online." -- FOSDEM
RAUC v1.5 Released
This release fixes a vulnerability in RAUC that can be exploited under certain circumstances to achieve a local privilege escalation. It provides both a mitigation for the vulnerability when using the existing bundle format as well as a new bundle format that uses dm-verity to continuously authenticate the update data while it is installed.
Pengutronix Christmas Tree
With the outside world getting colder and the days becoming shorter, we at Pengutronix decided to bring a bit of light in these dark days of the year.
Pengutronix at Live Embedded Event
Now that, due to the COVID-19 pandemic, everyone has gotten used to digitalisation and online conferences - it has never been easier to organise a conference and bring together all experts and interested parties for a few hours of intensive exchange of ideas on a certain topic.
Pengutronix at ESE Kongress
The Embedded Software Engineering Kongress is also taking place online this year and we would like to take the opportunity of easy participation to watch the lectures, join in the discussions and get into conversation.
ELCE 2020 - Recommended Talks
The Embedded Linux Conference Europe (ELCE) is the one biggest meetup of Embedded Linux developers in Europe. As usual Pengutronix has attended this conference - but this year from the warmth of our homes.
eMMC Hardware Partitioning
When designing an embedded system, one must consider both the application and the underlying hardware in combination, if the intended long-term stability is to be achieved. While we discussed the necessity of software updates in previous posts, in this article I describe a way to use a memory subsystem corresponding to its physics to achieve the best retention and lifetime of the whole system.
Pengutronix at the Embedded Linux Conference Europe
The schedule for this year's Embedded Linux Conference Europe (ELCE) has just been released. As in the last years Pengutronix contributes talks to current topics around Embedded Linux.
RAUC v1.4 Released
It's been 3 weeks ago now since the tag for RAUC 1.4 was created. But it is vacation time and so we have a good excuse for communicating things with some delay. Fortunately, the media team is back now and so also those of you who haven't noticed the new release yet will be informed about notable changes.
