May Newsletter: ChipWhisperer 3.4.1 Released, ARM Targets available, IEEE S&P, BH Training Deadline

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


A new ChipWhisperer release! This adds a lot of interest features we’ll mention quickly, including:

  • Quasi-automatic trace alignment.
  • Example firmware targets for STM32F0/F1/F2/F3/F4.
  • New SimpleSerial protocol (V1.1) with ACKs, simplifies usage with slow implementations.
  • Improved trace plotting allowing you to selectively include traces/waveforms.


Quasi-Automatic Trace Alignment

We’ve implemented a form of Dynamic Time Warping (DTW), which was suggested in the Elastic Alignment paper by J. van Woundenberg et al. The implementation is a little different to fit with our capture architecture, but accomplishes the goal of potentially aligning traces that have more than a simple physical shift (the following should be a small GIF showing you the usage):

STM32F Firmware Targets

Our previous newsletter mentioned the STM32F target board for the UFO. We’ve forged ahead and built examples of that for most of the STM32F series devices. You can see a full list of this on the wiki page. We’ll be commercially selling versions of that target too, for now we have the F0 available in the webstore along with the blank PCB.

To go along with this, we’ve released a new version of our SimpleSerial protocol. This protocol now has an ACK in it, which can help the ChipWhisperer know when it shouldn’t send something to a device that is busy processing the last command.

Improved Trace Plotting

For the longest time, you could only plot trace ranges. We now have a new trace plot widget that can plot arbitrary traces, and specify colours of them. For example here we are plotting trace #0-#5 in red with alpha of 0.3, #23 in green, and #35 in blue. This type of plotting is handy when you are looking at traces which might represent different code paths:

In the future we plan on improving this further to allow you to plot averages of groups, add offsets, etc. But for now you can specify both color codes & HTML colors (including transparency), which is very useful for seeing how often certain code paths are taken.

ARM Targets

As mentioned in the ChipWhisperer release notes, there is now a number of ARM targets for the UFO board. They all use the same STM32F PCB, so makes it very easy to target a bunch of different devices. We’ve got the blank PCB in the webstore along with limited quantities of the STM32F0 target board. The F1/F2/F3/F4 should be available shortly – we haven’t had time to run those boards through assembly yet. If you don’t want to solder let us know & we might be able to speed up a certain variant for you.

87C51 Targets

Do you like going old-school? Another new target is using the 8051 microcontroller. This target was a spin-off of a specific project so differs a little from our usual “cheap & basic” UFO target. But you may still find it interesting, and it comes preprogrammed with demos for AES, glitching, and TEA.

IEEE S&P and Other Conferences

Are you headed to IEEE S&P? Colin will be there in an academic capacity, but if you’re around please be sure to say hello! He’s easiest to track down on May 22nd at 1:45PM in Session #3, but will be around for the entire conference.

Colin will also be heading to RECON (Montreal in June) & ESCAR (Detroit in June). More details on those presentations will be coming.

BH Training Early Registration Deadline

Our training running at Black Hat USA 2017 has an early registration deadline of this Friday. One of the classes is almost sold out too, so if you want to ensure you make it in check the registration details soon. We’ll be (once again) updating our material this year to include some of the new features introduced in ChipWhisperer.

That’s all for now. Thanks again for listening to us blabbing on, hopefully you get a chance to try the new ChipWhisperer software, and look out for a few more new features in our next edition of NewAE News!

April Newsletter: Catch us at COSADE, CWPro Shipping, New Targets, New Tips

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


Are you around Paris, France? If so be sure to stop by and visit us at COSADE on April 13th & 14th. We’ll have a booth with our latest hardware to show off (including the ChipWhisperer Pro). We’ll also have our Spring 2017 catalog available (you can also grab a copy of the PDF here). Due to travel for COSADE we won’t be shipping this week, but will still be answering questions.

CWPro Shipping

In other news, the ChipWhisperer Pro is now shipping! Here’s a shot of the CW1200 in the hard case with custom foam we had made (which cause a little extra delay) – we think it was worth the wait:

You can see some more photos of the final version in the online store.

New UFO Targets

What about fun new targets? For the past six months we’ve been updating the targets that fit on the UFO board, but haven’t had the chance to release everything yet. The gerber files are available in the repository, but we’re now updating the wiki and making it even easier to build your own board (in case we don’t yet sell the finished one, or you just like the smell of solder in the morning).

You can see a list of all targets on the CW308T Category Page in the wiki. Some of them have links to OSH Park so you can order PCBs with a single click, but otherwise you can download gerbers of them for submission to your preferred PCB fab (we don’t get any kick-backs from OSH Park, so don’t feel obligated to support us). Some also have link to a “1-Click BOM“, which requires a small browser plugin but will then allow you to easily order the BOM from Digikey or other suppliers.

For example we’ve got a STM32F target board – it supports a number of STM32F devices in TQFP64 packages, but so far we have examples building for the STM32F415. We’ll be selling it shortly, but if you can’t wait gerbers are already online.

One of the first boards we will have commercially available is the MPC5748G target board (which isn’t documented yet online). This rather interesting one has three PowerPC cores alongside some interesting peripherals (it’s designed for automotive applications). See a shot of the current status below from our latest run:

Knowledgebase & Tips

We’ve been expanding our wiki into something of a knowledge base. You can see for example the Knowledge Base category now contains a few new tips – something we’re going to be expanding in the coming months. We’ve also experimented with video tips, something we did for demonstrating how to use the H-Field probe. Hopefully you find this format useful, and enjoy having some stand-alone pieces of information.

Software Update

Finally to close off the newsletter – ChipWhisperer software version 3.3.0 has been released. This version adds support for the ChipWhisperer-Pro. It hasn’t yet been pushed to the pypi server (allowing you to pip install), but expect that in the next day or two.

This version also includes the “downsampling” feature for the ChipWhisperer-Lite & CW1200, which means you can do attacks on asymmetric crypto. If you’ve got the CW1200 it has an additional streaming mode, but the downsampling might be enough to at least perform some basic SPA and similar attacks.

We’ve also improved the processing of captured waveforms – this was done to improve performance of some huge traces coming from the CWPro in streaming mode, but you will see speed-ups even with the CW-Lite. And if you want the fastest capture speed (in terms of traces/min, this won’t affect your sample rate), be sure to disable waveform redraw , which is another example of the type of tips we are adding to the knowledge base.

That’s all for now from NewAE – just a quick update to keep you informed of the latest changes.

ChipWhisperer Training at Black Hat USA 2017

NewAE Technology Inc. will be returning to Black Hat USA 2017 to put on it’s 2-day intensive training on side-channel power analysis and glitching. This training is hands-on, and uses the ChipWhisperer-Lite platform to give students the chance to perform real side-channel power analysis and glitching attacks.
The course uses the open-source ChipWhisperer project ( 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.

NewAE at COSADE 2016 in Austria – April 14/15

NewAE Technology Inc. is proud to announce that it has signed on as a gold sponsor of COSADE 2016, and will be exhibiting some of it’s products at this conference. This will include it’s newly released CW305 Artix FPGA target board. Be sure to stop by as we’ll have lots of interesting products, and you can help shape where our future products go!

In addition to exhibiting, we will be presenting some recent research results. Colin O’Flynn will also be presenting a paper entitled “Power Analysis Attacks against IEEE 802.15.4 Node“, which uses the ChipWhisperer platform as part of the demonstrated attack. We are continuing to demonstrate how side-channel power analysis can be a threat on real systems, and remains something every embedded engineering needs to be aware of.


Since 2010, COSADE provides an international platform for researchers, academics, and industry participants to present their work and their current research topics. It is an excellent opportunity to exchange on new results with international experts and to initiate new collaborations and information exchange at a professional level. The workshop will feature both invited presentations and contributed talks. [Source:]

CW305 Artix FPGA Board

The CW305 is NewAE Technology’s first FPGA target board. It brings tons of features including a simplified USB interface for talking to the FPGA, an external PLL for adjusting frequency response, a programmable VCC-INT supply, and diode protection for use in fault injection environments. Also available with a special BGA socket, giving you the ability to perform tests on multiple FPGA devices – perfect for checking Physically Unclonable Functions (PUFs) under the exact same environmental conditions across multiple FPGAs.

This board requires an external oscilloscope or capture box for performing the power measurement. If you are looking for a complete toolchain, purchase the CW305 along with the ChipWhisperer 2-Part version. This will provide you with a complete toolchain for experimentation on FPGA targets. Check out some of the features below, and you can see full pricing in our webstore. The board is now available for preorder, and is expected to start shipping by March 31, 2016.
