Embedded Linux Conference Europe

Embedded Linux is being used in more and more fields of: consumer, industrial and communication devices. Security is becoming an increasingly important issue for producers and users of these systems. Security of embedded systems is not only about: non-trivial root password, encrypted communication protocols and signed firmware. Both: the design of the device itself and the fact that It often works autonomously, in an inaccessible location, opens up a whole new possible fields of attack. Marcin Bis will review various methods of securing and encrypting whole system on various ARM-based hardware. Complete, working solution of ecryptfs, NAND encryption and secure boot techniques combined to provide a passively-secured system will be demonstrated, including a build system. The presentation is based on experience gained during R&D on home and industrial automation products.
