LIVE FROM TOKYO, IT'S #REALWORLDCRYPTO
(for a preview discussion of the whole program, check out our episode: securitycryptographywhatever.com/2023/03/24/rwc…)
First up in the PQC session is "How We Broke a Fifth-Order Masked Kyber Implementation by Copy-Paste" presented by Elena Dubrova
LIVE, IN THE FLESH, FROM AMSTERDAM, IT'S #REALWORLDCRYPTO!
@cryptojedi kicking off with logistics 
Kicking off with in fact, side channels: Spectre Declassified
🤞 fingers crossed 🤞 that #realworldcrypto 2022 will actually be in Amsterdam IRL 🦠
If the attacker has <= Q guesses, access to the FSB bucket will give no advantage over baseline guessing. Higher Q, greater security loss

I'm starting another thread because there were multiple branches in the previous one 🤦♀️

First up is the TLS session 🔒
First talk is Johanna Amann on measuring TLS 1.3 deployment in the wild with active and passive methods

Richard Barnes (@rlbarnes) just kicked off #RealWorldCrypto with a great overview of MLS, a new proposed standard for group message encryption. There’s still time to contribute: mlswg.github.io
Joanne Woodage (@joannewoodage) outlines a really cool attack on Facebook’s abuse reporting mechanism for encrypted messages. A great example of how popular schemes like AES-GCM can be easily misused. #RealWorldCrypto
The team also came up with a new one-pass authenticated encryption scheme based only on collision-resistant hash functions. It’s somewhat reminiscent of the Keccac team’s Keyac encryption based the a sponge construction: keccak.team/keyak.html
I admire the cryptographers who had the patience and courage to work on Privacy Enhancing Technologies for decades before the Snowden leaks, even though the world wasn't ready for them. This quote explains it perfectly. #RealWorldCrypto 
For many years, just about the only example of using fancy crypto (i.e., secure multiparty computation, zero-knowledge proofs, etc.) to protect privacy was the Danish sugar beet auction, which was frankly a bit silly. eprint.iacr.org/2008/068.pdf
Today, in addition to the obvious (cryptocurrencies), there are a growing number of examples of complex crypto protocols for privacy. After Snowden, tech companies have been far more willing to do the engineering. For example, this blog post by Cloudflare: blog.cloudflare.com/privacy-pass-t…
