Pengutronix Talks at ELC-E in Prague

The autumn conference highlight is the Embedded Linux Conference Europe (ELC-E), which takes place in Prague this year. The Pengutronix team will be present with four talks and two demo points / showcases, presenting current open source projects (RAUC, labgrid, etnaviv).

Two talks will take place on monday, 2017-10-23:

  • OP-TEE: Using Trust Zone to Protect Your Own Secrets: At 09:00, Marc Kleine-Budde talks about OP-TEE: since Linux 4.12, the infrastructure to use the Trusted Execution Environment on modern ARM cpus was merged into the mainline kernel. Marc shows how it can be used to store secret information in a (probably) secure way.
  • Automation Beyond Testing and Embedded Systems Validation: At 17:10, Jan Lübbe talks about the recent progress with automation in continuous testing setups and about the labgrid framework.

Another two takls will take place on wednesday, 2017-10-25:

  • Stable Device Tree ABI: It's Possible: At 14:15, Lucas Stach talks about strategies for ABI stability of the open firmware device tree.
  • Zerocopy Video Streaming the Easy Way: Finally, at 16:15, Philipp Zabel and Michael Tretter talk about how to use zerocopy mechanisms to avoid bandwith waste when streaming media on modern ARM cpus.

In addition, several open source projects relevant for us will be shown as part of the Technical Showcase on tuesday, 2017-10-24:

  • Etnaviv, the open source drivers for the i.MX6 3D graphics hardware
  • RAUC: Robust Auto Upgrade Controller
  • labgrid: test automation for continuous testing of embedded linux systems

Wir haben doch etwas zu verbergen: Schlüssel mit OP-TEE verschlüsseln

Moderne Linux Systeme müssen häufig zwecks Authentifizierung bei einer Cloud- basierten Infrastruktur oder einer On-Premise Maschine eigene kryptografische Schlüssel speichern. Statt der Verwendung eines Trusted Platform Modules (TPM), bieten moderne ARM Prozessoren die TrustZone-Technologie an, auf deren Basis ebenfalls Schlüssel oder andere Geheimnisse gespeichert werden können. Dieses Paper zeigt die Nutzung des Open Portable Trusted Execution Environments (OP- TEE) mit der Standardkonformen PKCS#11 Schnittstellen und i.MX6 Prozessoren von NXP als Beispiel.

Conferences 2021: A Retrospective and Outlook

Besides the improvements around embedded Linux software and ongoing development of Linux kernel components, the Pengutronix team took the corona pandemic as an opportunity: Last year, many conferences were accessible via internet, so we joined from the comfort of our home offices and shared our experiences and ideas with the community.
