    Really appreciated the opportunity to speak at about ’s investments in cryptographic research. I talked about my current programs (Brandeis and RACE) and possible future efforts (consensus protocols, zero knowledge). Slides are here:

    Ah wow that means a lot, ! You were the one to run with it and make some really cool tech.

    Some didn’t want to use the charging station last year at . Wonder if I would get takers for these?

    There is a big difference between falsifiable and standard, although falsifiable is a good step forward. Of course, standard is subjective. In 2001, my advisor Oded Goldreich did not agree for me to say “standard assumption” for DDH 😊. It’s a different world today!

    This is a really interesting EUROCRYPT 2020 paper. They seem to get “almost” the algebraic group model from “standard assumptions”... but those assumptions include subexponentially strong indistinguishability obfuscation. Is that kind of iO known from standard assumptions?

    Unfortunately we don’t understand these statistics well. Last year I sponsored a DARPA Young Faculty Award on quantifying vulnerability longevity, but the truth is we need much more study. (Cyber ITL is also doing important related work in this space I think) 3/2

    I liken this to the flu or other health issues. We don’t (or shouldn’t) blame people for being sick but are always looking to blame people who run vulnerable systems. We should think of these as *populstions* governed, at scaled, with statistics. 2/2

    Our understanding of vulnerabilities and their impact on a *population* or systems is super immature, especially when it comes to operational technology that is 1) mission critical but also then 2) slow to change. (1/2)

    Worst intelligence failure in Star Wars franchise is missing Palpatine’s fleet acquisition program. But I’m entertaining alternatives.

    Great line: “Technically, the apps aren't classified as malware because they limit their hidden functions to displaying ads.”

    "SIM swap" attacks have been in the news for years. They’ve enabled serious financial crimes and even a hack of the Twitter CEO's account. We spent 6 months researching how vulnerable wireless accounts are to these attacks. Our draft study is out today.
