 Yeah, hi everyone because it's like 10 30 at night and all we want to talk about is what is DARPA doing in cryptography? So why not? Okay, so hi. I'm Josh. I'm a program manager at DARPA. I run DARPA's cryptographic programs There are quite a number of them at this point. So There's a program called safer which just ended this year on indistinguishability obfuscation I'll just leave that one there. So Brandeis ends next year from a cryptographic standpoint It's focused on among other things kind of MPC with low party So like ten or fewer and moderate complexity computation, but like practical applications. So as an example at rule of crypto We talked about like assigning Ships to ports in like a couple of seconds where you didn't want to reveal the underlying ship locations or their speeds We're doing a lot of stuff involving like information deconfliction. It's fun stuff. Okay a program that just started this year In fact a couple months ago is called Resilient anonymous communication for everyone It's kind of if like torn signal had a baby so the way to think of it is Can we do end-to-end encrypted metadata secure messenger and do it by actually having MPC as the kind of underlying distributed system? So that the underlying kind of message passing system in of itself doesn't know what it's doing So, you know that might work, but it involves a massive party MPC But doing like very basic things so the kind of message allocation is not hopefully substantially more complicated than like coin tossing Two things that are ongoing. There's a program that's on that's been publicly announced called sieve Which has a giant name that I'm not going to say right now, and it's all about zero knowledge Specifically a zero knowledge for large complex problems Basically task one is build the actual problem statements for weird and interesting problems Do the actual proofs and then post-climacy or knowledge? There's a lot more to say about it And if you're curious Check out the BA which is this giant link or probably you should just Google DARPA sieve and see and see you can find Notably the due date for the proposals are a month from today So if this is a program you hadn't heard about yet, I'm surprised We're doing a zero knowledge program. It should be fun Okay, and finally I want to talk briefly about the DARPA young faculty award So for our definition of young is actually apparently a little broad so to be eligible You have to be a tenure-track faculty at a US institution within three years of tenure or more junior So interestingly you can be a non-us citizen at a US institution It turns out you actually can't be a US citizen at a non-us institution I don't know why that is and it's up to five hundred thousand dollars for the first two years You should be checking out fbo.gov or DARPA mill for the announcement Which I actually think is going to be out tomorrow With a due date once you see the announcement within a month or two I'm mentioning this because there will be a topic in cryptography specifically in the young faculty award The title of which is economic driven secure multi-party computation So basically the way to think of it is one of the interesting things that kind of Bitcoin taught us is you can take Frankly somewhat trivial crypto, right? So like you see DSA shot you and the like and then you bribe people and then because of the bribing You can make massive secure computation right massive distributed secure computation So that tends to tell us that like maybe this whole like economic utility thing might have relevance when we want to think about kind of large-scale distributed computation So this young faculty award will be specifically about that Please don't come at me with like a covert or a fairness thing that we've known about for a very long time The point is to actually be pretty broad in general about Kind of trying to marry kind of economics with distributed computation should be fun What could possibly go wrong? if you have thoughts About you know, what DARPA is doing right or probably more interestingly what DARPA is doing wrong in cryptography Feel free to find me and yell politely And tell me of the kinds of things that you think we should be addressing but are not so thank you
