We're back! With an episode on lattice-based cryptography, with Professor Chris Peikert of the University of Michigan, David's alma mater. When we recorded this, Michigan football had just beaten Ohio for the first time in a bajillion years, so you get a nerdy coda on college football this time!Transcript: https://securitycryptographywhatever.com/2022/03/12/lattices-and-michigan-football-with-chris-peikert/Slides: https://web.eecs.umich.edu/~cpeikert/pubs/slides-qcrypt.pdfLinks:He Gives C-Sieves on the CSIDH: https://eprint.iacr.org/2019/725Lattice-based Cryptography: https://cims.nyu.edu/~regev/papers/pqc.pdfNIST PQC Competition: https://csrc.nist.gov/Projects/post-quantum-cryptography The 2nd Bar Ilan Winter School on Cryptography Lattice- Based Cryptography and Applications: https://www.youtube.com/playlist?list=PL8Vt-7cSFnw2OmpCmPLLwSx0-Yqb2ptqOA Decade of Lattice Cryptography: https://eprint.iacr.org/2015/939.pdfFind us at:https://twitter.com/scwpodhttps://twitter.com/durumcrustulumhttps://twitter.com/tqbfhttps://twitter.com/davidcadrian"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@davidcadrian)
