Did I just send 25 letters by recorded post to representatives of the Italian government, parliament, and EU institutions, speaking out against ChatControl?

Yes, it looks like I did.

Mathematical #cryptography question. Suppose you wish to store a very large number (240 or more) of messages. All of these messages have the same relatively short length, on the order of 215 bits, and are to be encrypted with the same symmetric key.
In this regime, how do you size the IV and MAC for some target security level k? Still just k bits each, or does it get more interesting?

This paper is SO good.

The war on crypto never ends. The war on privacy, civil rights, security and freedom of speech never ends.
This time we are dangerously close to lose. The "Child Sexual Abuse" (CSA) EU regulation proposal, more aptly nicknamed "ChatControl", will be voted AGAIN this October, and many countries who opposed it last year are now undecided. The proposal at its roots aims at allowing authorities to break end-to-end encryption for the usual reason: "because of the children". As a father of two, I am disgusted by this recurring, cheap rhetoric.

"Selfie attack"? It really exists?

Oh dear.
Researchers figure out how to undermine Fiat-Shamir and the Random Oracle Model to validate untrue inputs.
This has quite serious potential implications for blockchain trust although the full extent isn’t yet known.

A friend with an iPhone want to read and write PGP-encrypted emails: what's the cheapest and simplest approach I can suggest him?
I know nothing about Apple products, but I guess they have a default mail agent. Yet I can't find online how to configure PGP.
