July Newsletter: New Tutorials, New Features, Updated UFO Boards, More ARM

Read the latest newsletter over on our TinyLetter page. Be sure to subscribe to get these updates yourself.


Welcome to NewAE News – July edition. Unlike most of our previous newsletters we have nothing new to sell you, but lots of new stuff to show off.

New Tutorials – RSA & ARM-Based AES

The most interesting news is there are two new tutorials you can perform! The first one is breaking RSA, or more accurately breaking part of RSA, as the entire algorithm is too slow to run on our XMEGA device. But it’s using a real RSA implementation as a base.

You can check out that tutorial as number B11 on the wiki. As a bonus you can also download a few traces we recorded at https://github.com/newaetech/chipwhisperer-examples/tree/master/tutorials/B11/example_traces in case you want to play through without hardware.

We’ve also added a tutorial breaking an implementation of AES, as commonly performed on 32-bit devices, where you use a special T-Table to speed up the algorithm. That is tutorial A8 on the wiki. Performing this tutorial requires an ARM device (such as our STM32Fx targets), but again we’ve posted some traces at https://github.com/newaetech/chipwhisperer-examples/tree/master/tutorials/A8/example_traces .

As you might have guessed we’re going to be working towards making a larger repository of example traces available, to make it even easier to work through all the tutorials even if you don’t have the required hardware.

New Features

We’ve also released a new version of ChipWhisperer, 3.5.3. Besides the usual small updates, this one also sees a new FPGA bitstream for both the Lite and Pro. This adds a “Trigger Length” feature that can report back how long the trigger was active for, handy for figuring out how long of a capture you need:

This version also finally adds a Windows installer, which installs Python (with all required modules), ChipWhisperer, and an update method based on getting the latest from GIT.

UFO Board Updates

All UFO boards being shipped now have a small update – a reset button! This grounds the nRST net on the UFO board, which can be handy when working through tutorials that require you to reset the device frequently:

More ARM

We’ve also updated all of our starter kits to now include an ARM target. We’ll now be shipping all kits (UFO, Level 1 & 2 Starter Kits, ChipWhisperer Pro) with the XMEGA Target + a STM32F target. We were using STM32F0 initially, but have been able to successful port everything to the STM32F3 which includes a whopping 40K of SRAM, so you can run even more advanced algorithms on this device.

The trust ATMega328P will still be available as an add-on, but based on your feedback we’ve decided to also include an ARM target. Now all of your starter kits will include both an 8-bit and a 32-bit target!

Black Hat, Trainings, CHES, and More!

This is a short newsletter as Colin is busy preparing for Black Hat. If you’ll be around Colin will be there until Thursday evening (27th), so send him a tweet (@colinoflynn) or email us to try and meet up! He’ll be giving a talk on Wednesday morning (10:30am) and showing the ChipWhisperer off at Arsenal on Thursday at 2:30pm.

If you’ll be at DEFCON, the Hacker Warehouse booth will be stocking the ChipWhisperer-Lite too! So you can grab one in person.

We’ll also be at CHES in September, and will have more details of what new hardware we’re showing off in the next newsletter. There should be some fun new tools to explore even more aspects of hardware security.

If you missed the announcement from the last newsletter, we’re also going to be running a training in San Francisco this November 6th & 7th. It’s being run alongside training courses by Dmitry Nedospasov, Joe Fitzpatrick, Joe Grand, and Michael Ossmann. We’ll be running our 2-day training course (same one as at Black Hat USA). You can see details at https://hardwaresecurity.training/ , and contact us for more information (email sales@newae.com ) or buy a seat online at the previous URL.
