Cryptography, privacy, quantum security, infosec, retro vibes.
I am a mathematician and computer security scientist, with a strong interest in cryptography and anonymity, specialized in quantum security and complex cryptographic protocols. I am also a privacy hacktivist and public speaker, blahblahblah, read my Linkedin bio for this s**t, this is my Mastodon corner.
I co-develop Shufflecake, an open source privacy disk encryption tool to help journalists, activists, and whistleblowers evade unjust prosecution.
I am an advocate of digital self-sovereignty. You will see me often ranting about Big Tech, enshittification, and surveillance capitalism.
Fascinated with anime, Japan, RPGs, retro computing, and all things 80-90's. Notice I wrote "fascinated", not "knowledgeable".
Here you won't find peace nor forgiveness, but just: #cryptography #privacy #quantum #security #infosec #retro vibes!

I'm off to Perugia tomorrow for the International Journalism Festival! If you're also in Perugia, and would like to discuss political cartoons or graphic journalism, let me know and we'll meet for a coffee or a spritz :)
And consider joining one of the two workshops I'll be giving, one on political cartoons and one about humor and democracy:

VeraCrypt to stop developing Windows application due to Microsoft revoking their driver signing certificate:

We are sorry to hear this turn of events and we wish VeraCrypt team all the best. For us, Windows was never an option.

Sorry to hear about this turn of events, but it was pretty much to be expected given the way the world is turning, and Microsoft being Microsoft.
Switch to Linux if you can, and come give Shufflecake a try ;)

Today is a day when people post fake and outlandish stuff online to confuse and shock outhers.
In other words, it's a Wednesday.
I am happy to share that, as of today, I am starting a new position as Head of Cryptography at Palantir! I will join a team of great researchers with unmatched talent and pragmatically flexible ethics. Our mission is to drive innovation and make sure that security and privacy are available to everyone without needlessly hindering the legitimate collection of data to improve user experience and safeguard national security!

New breakthrough results for quantum attack resource estimates against 256-bit elliptic curves: most ECC-based applications including ECDSA and Bitcoin could be at risk way sooner than expected:
We estimate that these circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical qubits in a few minutes [...] This is an approximately 20-fold reduction in the number of physical qubits required to solve ECDLP-256"
Interestingly, Google and friends did not release the blueprint for the attack circuit. In the name of "responsible disclosure", they only provided a zero-knowledge proof (ZKP) proving that the circuit works. This is, I think , a first in the realm of cryptanalysis disclosure.
The statement that our ZK proof demonstrates is the following: we possess a classical reversible circuit of a specified size which on most inputs correctly computes point addition on the elliptic curve secp256k. This is the primary bottleneck in Shor’s quantum algorithm
I have been saying this since the 2010s: quantum cryptanalysis is one of those non-linear technology progresses that will take everyone by surprise when it arrives. Qubits quality and numbers go up, error-correction and attacks improve, investments scale up accordingly. It's a perfect storm of compound factors. Folks didn't listen, now time is ticking.

Are we having fun yet?
Quantum computers have the potential to perform computational tasks beyond the reach of classical machines. A prominent example is Shor's algorithm for integer factorization and discrete logarithms, which is of both fundamental importance and practical relevance to cryptography. However, due to the high overhead of quantum error correction, optimized resource estimates for cryptographically relevant instances of Shor's algorithm require millions of physical qubits. Here, by leveraging advances in high-rate quantum error-correcting codes, efficient logical instruction sets, and circuit design, we show that Shor's algorithm can be executed at cryptographically relevant scales with as few as 10,000 reconfigurable atomic qubits. Increasing the number of physical qubits improves time efficiency by enabling greater parallelism; under plausible assumptions, the runtime for discrete logarithms on the P-256 elliptic curve could be just a few days for a system with 26,000 physical qubits, while the runtime for factoring RSA-2048 integers is one to two orders of magnitude longer. Recent neutral-atom experiments have demonstrated universal fault-tolerant operations below the error-correction threshold, computation on arrays of hundreds of qubits, and trapping arrays with more than 6,000 highly coherent qubits. Although substantial engineering challenges remain, our theoretical analysis indicates that an appropriately designed neutral-atom architecture could support quantum computation at cryptographically relevant scales. More broadly, these results highlight the capability of neutral atoms for fault-tolerant quantum computing with wide-ranging scientific and technological applications.
Dear LinkedIn,
It is great that you respect my privacy. But I'm confused: I thought I had previously already denied AT LEAST 89 OTHER TIMES my consent for you to profile me, track me with 3rd party cookies, anally probing me, and generally making my life a bit more miserable.
To you and all the other countless buffoons out there: could you please kindly f**k off?
