Amazed at the sheer garbage I'm finding in my slides on Diffie-Hellman prior to class! Almost done rewriting... so glad I do two hours of prep before each lecture.

A group of physicists claim they have proof that true randomness exists. This has implications for encryption protocols and computing, but (if true) would also indicate that the past does not determine the present.

The EU wants to spend your money to assemble a giant mass surveillance machine with little effect on harm against children. Chat Control is not effective, weakens security for all and does not respect privacy. Contact your EU representatives and let them know.

It looks like the website for our Applied Cryptography course at AUB is now the top search result on Google for "applied cryptography". The website now has over 200 unique visitors a day from all over the world, and AFAIK the course materials are now being used in at least five universities.

“by far the most likely outcome is for the tech to be used for massive enrichment and centralisation of power into an even smaller elite than before, with even more terrifying mechanisms of control at their disposal.”

Until now, if you lost or broke your phone, your Signal message history was *gone,* a real challenge for everyone whose most important conversations happen in Signal. So, with careful design and development, we’re rolling out opt-in secure backups.

Took clips of AUB's Commencement Ceremony! It was glorious. We sang the Lebanese National Anthem and then President Fadlo Khuri started rapping Eminem's Lose Yourself. Although, on the surface, it's funny, it signals a commitment to transgressive, free intellectual expression.
