Dear everyone. From what I can tell, these researchers claim to have cracked 20-bit RSA (which I can crack on a MacBook) using a D-Wave computer (which is not a general-purpose quantum computer) and an algorithm that may or may not even work at scale.

1) TEEs are not secure enough for the most exciting use cases Right now, they're better than nothing, but if we want to build a house with TEEs in the foundation, there's a long way to go That's the topic of a blog series @sbellem @socrates1024 and I are starting (with friends)


This is really bad, all @Infineon secure elements vulnerable, extraction of private key (as bad as it gets basically). These are certified secure hardware, this should not be possible or at least not this easy 😅

We are very excited to share our last research work: 𝐄𝐔𝐂𝐋𝐄𝐀𝐊, authored by Thomas Roche. An electromagnetic Side-Channel Vulnerability in the ECDSA implementation of all Infineon security microcontrollers, notably impacting all YubiKey 5 Series. ninjalab.io/eucleak/

ECB's offline digital Euro layer sounds extremely close to the ecashact.us vision. Still the only US digital dollar option to take privacy seriously.

Canada gets it

Having completed its public consultation on a potential digital dollar, the @bankofcanada is committing itself to researching a CBDC that won't require ID, similar to banknotes and prepaid cards. 👀👀 bankofcanada.ca/digitaldollar/…
