@matthew_d_green given that photos are listed among protected data, I wonder what they did with brand new shared library… new is versions for friend/family as well (and a shared key different than yours own) or shared photos excluded !?

@matthew_d_green update: so shared albums are ko, but it seems shared library can be ok: https://support.apple.com/en-gb/HT202303#advanced , section “Sharing and collaboration” …Still in doubt if AppleTV+ app on third party tv (listed among iCloud devices) could forbid ADP activation (not simply trying yet ‘cause I need to replace an old iPad acting as HomeKit hub)

Gödel in Cryptography: Effectively Zero-Knowledge Proofs for NP with No Interaction, No Setup, and Perfect Soundness

A zero-knowledge proof demonstrates that a fact (like that a Sudoku puzzle has a solution) is true while, counterintuitively, revealing nothing else (like what the solution actually is). This remarkable guarantee is extremely useful in cryptographic applications, but it comes at a cost. A classical impossibility result by Goldreich and Oren [J. Cryptol. '94] shows that zero-knowledge proofs must necessarily sacrifice basic properties of traditional mathematical proofs --- namely perfect soundnes

A essere meno politically-correct si potrebbe considerare che, visto quello che conta il voto di maturità e visto quanta visibilità danno questi atteggiamenti nel mondo dell’apparire moderno, uno potrebbe anche essersi fatto due conti: meno sbatti, molta visibilità, zero ripercussioni… quindi ci potrebbe anche essere molto poco idealismo e molta concretezza trash: il meccanismo di incentivi e disincentivi di fatto autorizza anche a questa lettura.

Schneier on Security

Simson Garfinkel on Spooky Cryptographic Action at a Distance - Schneier on Security

Excellent read. One example: Consider the case of basic public key cryptography, in which a person’s public and private key are created together in a single operation. These two keys are entangled, not with quantum physics, but with math. When I create a virtual machine server in the Amazon cloud, I am prompted for an RSA public key that will be used to control access to the machine. Typically, I create the public and private keypair on my laptop and upload the public key to Amazon, which bakes
