Course Description

Side-Channel Power Analysis - that freaky method of extracting secret keys from embedded systems that doesn’t rely on exploits or coding errors. It can be used to read out an AES-128 key in less than 60 seconds from a standard implementation on a small microcontroller. Are your products vulnerable to such an attack? This course is loaded with hands-on examples to teach you not only about the attacks and theories, but how to apply them.

The course uses the open-source ChipWhisperer project (www.chipwhisperer.com) for both hardware & software tools, meaning attendees can immediately take the knowledge learned in this course and apply it in real life. The course includes a ChipWhisperer-Lite, so students walk away with the hands-on hardware used during the lab.

During the two-day course, topics covered will include: theory behind side-channel power analysis, measuring power in existing systems, setting up the ChipWhisperer hardware & software, several demonstrated attacks and labs, understanding and demonstration glitch attacks, and analyzing your own hardware.

Side Channel Power Analysis & Fault Attacks have never been more accessible, and testing your products has never been this inexpensive or easy.

Targets

This course targets low-level embedded systems - such as 8-bit, 16-bit, and 32-bit microcontrollers (including ARM and PowerPC). The hands-on portions will use an Atmel XMEGA but the techniques are directly applicable to other microcontrollers. These techniques are most useful when attacking systems running bare-metal or a RTOS, which could include for example the bootloader mode on an automotive MCU.

Audience

This course is aimed at anyone who has previously designed or reverse-engineered embedded systems. Students are expected to be familiar with both C and Python (in-depth experience is not required, but knowledge of general syntax and how to build programs in both).

General embedded design experience is assumed - students should be familiar with UARTs, bootloaders, bus interfaces, use of microcontroller peripherals, etc. The course does not require any specific knowledge but the course content will be most valuable to someone experienced in this area.

What To Bring

Students MUST bring a laptop with approximately 15GB of free space. A variety of (Python-based) tools will be installed and used, which can run on Linux & Windows. To simplify the class, a VMWare image will be provided which has all tools installed, but students are free to directly install the tools on their own computer.

Students are encouraged to bring a computer with VMWare Workstation already installed to reduce setup time.
