FLOE! 🧊 #realworldcrypto

Supports exabytes #realworldcrypto

What type of security are we trying to achieve? nOAE(2) #realworldcrypto

Tweak nOAE to get randomized raAE notion #realworldcrypto

There are no existing commitment notions [!] #realworldcrypto

Encoding positions as parameters #realworldcrypto

Modeled in random access real-or-random setting #realworldcrypto

Existing schemes (Tink streaming, STREAM) remain secure under ra-ROR #realworldcrypto

Construction reduces to mu-PRF security of HMAC-Expand -SHA-384 and mu-ROR$ security of the AEAD (AES-GCM) #realworldcrypto

Define context commitment for raAE, ra-CMT #realworldcrypto

Q: This would be great for secure backups of things like DBs A: Yes! #realworldcrypto

Coffee time! #realworldcrypto

heh #realworldcrypto

grumble grumble chat control #realworldcrypto

Implies that inspection happens at the sender or receiver ends #realworldcrypto

Significant change of the trust boundary #realworldcrypto

General monitoring is already rejected #realworldcrypto

> philosophy of science YES #realworldcrypto

ChatControl as a primitive #realworldcrypto

When measurement replaces deliberation: ' “Technologies of hubris” are governance tools that try to render uncertainty manageable through prediction, calculation, and claims of control." #realworldcrypto

The system starts to feel objective, even though the value judgments are being encoded into the machine #realworldcrypto

“Technologies can be understood as forms of order as their architectures predispose certain social and political outcomes.” #realworldcrypto

'pls don't build the torment nexus' #realworldcrypto

“Some questions are not just unanswered; they are marginalized by how research agendas, funding systems, and institutions decide what gets studied." #realworldcrypto

If we can name the failure modes clearly, we can help policy avoid building brittle infrastructure. #realworldcrypto
