Using the Pyroelectric Effect to Identify Broken MLCC Capacitors Vintage computer hardware can fail in a variety of fascinating ways, with [Bits und Bolts] dealing with an interesting failure mode, in the form of degraded MLCC capacitors on Voodoo …read more

Machdyne Schoko with ESP32-S3 as JTAG bridge

Lattice ECP5 in SSPI mode

new SpiOverJtag support able to access Flash in complex JTAG chain

🎉 openFPGALoader v1.0.0 is out!
Major highlights:
• Complete spiOverJtag rework for Xilinx(complex chains)
• New Sponsors/Partners section
• AlteraFPGA MAX10
• Lattice ECP3 + ECP5's SSPI
• EspressifSystem ESP32-S3 as JTAG

Thanks to all!

board layout in KiCad with lots of layers and colors

i reverse-engineered the Raspberry Pi Compute Module 5! check it out at github.com/schlae/cm5-r...

Je viens de voir ton message, je t'ai envoyé un mail.

Part 2 of my SCA journey is now live: I demonstrate a successful CPA attack on an unmodified device during AES key unwrap.

I've just had a look at the errata list, and yes, it's not short...

Are these bugs documented somewhere?

For the past while J-P at @newae.com has been working on a major #ChipWhisperer doc refactor - this is now live, check out chipwhisperer.readthedocs.io/en/latest/in... . It moves software, hardware, and even some tricks/tips all into once place using Jupyter Books. Huge improvement in usability!

OK, it's official on the website now: KiCad 9 is out!

Ghidra 11.3 is OUT!


PyGhidra is the new feature to be excited about.

It’s a Python library providing direct access to the Ghidra API. 



I expect this to massively increase Reverse Engineering tool development, as it significantly reduces the barrier to entry for Ghidra interaction.

What's this? Oh, nothing much. Just KICAD VERSION 9RC2 dropped! We are only a couple weeks away from the final release. Test out the nightly builds now and see if you can find any showstoppers that we can fix before that happens.

I've been diving into electromagnetic (EM) side-channel attacks with Correlation Power Analysis (CPA) these past few weeks and just published a blog article about my journey: collshade.fr/articles/cpa...

A die photo of the Pentium processor with the main functional blocks labeled including the caches, instruction fetch and decode, integer execution, and floating point. The image consists of complex patterns of rectangular regions in reddish and brownish colors. The image zooms in on a small part of the floating point unit giving a detail of an adder and PLA circuit.

Intel launched the Pentium processor in 1993. Unfortunately, dividing sometimes gave a slightly wrong answer, the famous FDIV bug. Replacing the faulty chips cost Intel $475 million. I reverse-engineered the circuitry and can explain the bug. 1/9

I understand why people need HPC to work on side channel. It took me hours to get this convergence plot. It's ONE byte and only 10000 traces...

"In AES decryption, the round keys are used in reverse order compared to encryption. The first round key for decryption is actually the last round key of the encryption key schedule." 🤦
I was looking for my key, not that....
Now I start to see good key guess!

KiCad is proud to announce the release of 8.0.7

We have lots of bug fixes and speed improvements in this release, so upgrading is highly recommended!

I made some progress. I couldn't find any correlation. Turned out my traces were not properly aligned. As suggested by
@Baldanos
I made a CPA on the cyphertext just to be sure I can detect something. And yes, this is my input bytes leaking:

Hello AES!

I didn't know that italic could be a variant for part numbers 🤨
