'Jerry Solinas deserves a raise' with Steve Weis
We explore how the NIST curve parameter seeds were generated, as best we can, with returning champion Steve Weis!“At the point where we find an intelligible English string that generates theNIST P-curve seeds, nobody serious is going to take the seed provenance concerns seriously anymore.”Transcript: https://securitycryptographywhatever.com/2023/10/12/the-nist-curvesLinks:- Steve’s post: https://saweis.net/posts/nist-curve-seed-origins.html- ANSI X9.62 ECDSA: https://safecurves.cr.yp.to/grouper.ieee.org/groups/1363/private/x9-62-09-20-98.pdf / FIPS 186-2 https://csrc.nist.gov/files/pubs/fips/186-2/final/docs/fips186-2.pdf- “A RIDDLE WRAPPED IN AN ENIGMA”: https://eprint.iacr.org/2015/1018.pdf- https://arstechnica.com/information-technology/2015/01/nsa-official-support-of-backdoored-dual_ec_drbg-was-regrettable/- https://www.muckrock.com/foi/united-states-of-america-10/origin-of-fips-186-4-elliptic-curves-over-prime-field-seed-parameters-national-institute-of-standards-and-technology-78756/- https://www.muckrock.com/foi/united-states-of-america-10/origin-of-fips-186-4-elliptic-curves-over-prime-field-seed-parameters-national-security-agency-78755/- Filippo’s bounty: https://words.filippo.io/dispatches/seeds-bounty/- Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters - NIST 800-186 with Curve25519 and friends- RFC 8422: Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS) Versions 1.2 and Earlier- https://www.rfc-editor.org/rfc/rfc4492#section-6- https://blog.cryptographyengineering.com/2017/12/19/the-strange-story-of-extended-random/- https://en.wikipedia.org/wiki/Bullrun_(decryption_program)- https://en.wikipedia.org/wiki/BSAFE- https://sockpuppet.org/blog/2015/08/04/is-extended-random-malicious/"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@davidcadrian)

Software Safety and Twitter with Kevin Riggle
We talk to Kevin Riggle (@kevinriggle) about complexity and safety. We also talk about the Twitter acquisition. While recording, we discovered a new failure mode where Kevin couldn't hear Thomas, but David and Deirdre could, so there's not much Thomas this episode. If you ever need to get Thomas to voluntarily stop talking, simply mute him to half the audience!https://twitter.com/kevinriggleTranscript: https://securitycryptographywhatever.com/2022/11/24/software-safety-and-twitter-with-kevin-riggle/ErrataIt was the Mars Climate Orbiter that crashed due to a units mismatchDavid confused the Dreamliner with the 737 MaxLinkshttps://free-dissociation.com/blog/posts/2018/08/why-is-it-so-hard-to-build-safe-software/https://complexsystems.group/https://how.complexsystems.fail/https://noncombatant.org/2016/06/20/get-into-security-engineering/https://blog.nelhage.com/2010/03/security-doesnt-respect-abstraction/http://sunnyday.mit.edu/safer-world.pdfhttps://www.adaptivecapacitylabs.com/john-allspaw/https://www.etsy.com/codeascraft/blameless-postmortemshttps://increment.com/security/approachable-threat-modeling/https://www.nytimes.com/2022/11/17/arts/music/taylor-swift-tickets-ticketmaster.htmlhttps://www.hillelwayne.com/post/are-we-really-engineers/https://www.hillelwayne.com/post/we-are-not-special/https://www.hillelwayne.com/post/what-we-can-learn/https://lotr.fandom.com/wiki/Denethor_IIhttps://twitter.com/sarahjeong/status/1587597972136546304"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@davidcadrian)

Matrix with Martin Albrecht and Dan Jones
No not the movie: the secure group messaging protocol! Or rather all the bugs and vulns that a team of researchers found when trying to formalize said protocol.
