Using the TPM - It's Not Rocket Science (Anymore) - Johannes Holland & Peter Huewe, Infineon Technologies AG
Nowadays, virtually all consumer PCs/laptops contain a TPM2.0 security chip, the Trusted Platform Module. Moreover, the TPM finds its way into more and more modern embedded devices. But what is the TPM and how can we use it on Linux? The TPM has the potential to enhance security in a variety of use cases ranging from SSH, VPN, disk encryption, and more. Since it is so powerful, it may be hard to use at times. But do not fret - the tpm2-software project, especially its new TPM Software Stack (TSS) Feature API (FAPI) library, enables anyone to use the TPM. This talk gives an introduction on how to use the TPM the easy way, using recent contributions to the TPM ecosystem like the TSS FAPI. After a brief overview of the involved hard- and software, this talk will dive into how to get started with the TPM and show how it can be used to perform fundamental security tasks. Afterwards, recent additions like the TPM PKCS11 middleware and the OpenSSL engine will be presented - enabling TPM integration, perhaps without writing a single line of code. In the end, the TPM open source ecosystem will be discussed, and how to become part of it. Want to start hacking? We got you.

OP-TEE is Ready: Let's Use It! - Rouven Czerwinski, Pengutronix e.K.
OP-TEE for i.MX6 SoCs is production ready, so we finally have a fully mainline way to use TrustZone on a widely available platform. So what are the scenarios where we it can increase security or allow new features? This talk will present the current state of OP-TEE from an upstream perspective on i.MX6 SoCs and show two different Trusted Applications (TAs) which provide secure data storage or TPM functionality. One of the presented applications will be the PKCS#11 TA which is currently being upstreamed into the mainline OP-TEE project. In conjunction with the OpenSSL PKCS#11 engine, it can be used to store client certificate data which can not be extracted from the device. The other application will be the Microsoft firmware TPM, which is provided as an out-of-tree TA with an upstream Linux kernel driver. It is meant as a replacement for conventional hardware TPMs and provides a tighter coupling to the chosen SoC. Furthermore this talk will highlight the necessary steps to actually secure OP-TEE on your chosen SoC, using the i.MX6 platform as an example.

Issues with Open Source License Compliance in Consumer Electronics - Tim Bird, Sony
Complying with the myriad licenses for software that is used in a modern consumer electronics device can be a complicated process. In this talk, Tim will discuss lessons learned from license compliance activities with Sony consumer electronics products. Tim will describe best practices for things like offers for source, software distribution, and rebuildability of provided source. The GPL license requires ""complete and corresponding source"". Tim will explain what this means, and how that interacts with things like secure product lockdown. The history of the GPL v2 license, and intent of Linux kernel community leaders will be presented. Attendees should gain a better understanding of compliance requirements, and what issues to watch out for in managing the source code and requests for source for their embedded Linux products.

Share System Resources on Multi-Processor System - Lionel Debieve, STMicroelectronics
New SoCs often embed multiple heterogeneous processors. Buses, memories or peripherals managed by the SoC could be allocated to different processors. Shared system resources, such as clocks or power controllers, might be critical in the system and need to be controlled by a high level privileged and trusted entity. Whatever the hardware solution used, software drivers must remain agnostics. The talk will present the shared resources constraints and how the STM32MP1 explores and extends the ARM System Control and Management Interface as solution for such shared resources management.
