Whether they are served with cream cheese and lox or hummus, there is probably nothing better than a fresh bagel. But did you know that bagels have a truly interesting history? From medieval German monasteries to Poland, and from the Jewish diaspora in New York and Montréal.\n\nSo in this talk, I'll be covering the important questions of our time: Where does the Bagel come from? Where do you get the best Bagels (Montréal or New York)? And how do all these doughnuts with rigor mortis differ? And of course, you'll learn how to bake a proper bagel.\n\nCome by and learn more than you ever wanted to know about Bagels (and eat there predecessor while listening to me).\n\nLicensed to the public under https://creativecommons.org/licenses/by/4.0/","original_language":"eng","persons":["Johannes Bechberger"],"view_count":10,"promoted":false,"date":"2026-10-31T20:15:00.000+01:00","release_date":"2026-11-05T00:00:00.000+01:00","updated_at":"2026-11-05T22:45:16.435+01:00","tags":["106","2026","dhcp26","D002 Vortragsraum","dhcp26-eng","Day 2"],"length":2829,"duration":2829,"thumb_url":"https://static.media.ccc.de/media/events/dhcp/2026/106-317dc43f-3c9a-5463-b436-bdd4ccf44167.jpg","poster_url":"https://static.media.ccc.de/media/events/dhcp/2026/106-317dc43f-3c9a-5463-b436-bdd4ccf44167_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/dhcp/2026/106-317dc43f-3c9a-5463-b436-bdd4ccf44167.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/dhcp/2026/106-317dc43f-3c9a-5463-b436-bdd4ccf44167.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/dhcp26-106-bagel-history-of-a-bread-with-a-hole","url":"https://api.media.ccc.de/public/events/317dc43f-3c9a-5463-b436-bdd4ccf44167","conference_title":"Die Heilbronner Chaos Party 2026","conference_url":"https://api.media.ccc.de/public/conferences/dhcp26","related":[]},{"guid":"0d61e9d0-6ef4-572b-9349-e98540168aa0","title":"All Cars Are Broadcasting - Die Public-Key-Infrastruktur der (Daten)Autobahnen","subtitle":null,"slug":"dhcp26-105-all-cars-are-broadcasting-die-public-key-infrastruktur-der-daten-autobahnen","link":"https://talks.dhcp.cfhn.it/dhcp26/talk/8X8DXT/","description":"Much has been said recently about Coöperative Intelligent Transport Systems (C-ITS) and how these standards are used to broadcast vehicle location, upcoming roadworks, traffic light phase and timing, and other such useful information directly into the infotainment system of your car, or indeed bike. As [opentrafficmap.org](https://opentrafficmap.org) has demonstrated, anyone with an ESP32 can send and receive these messages, as they are sent as simple WiFi packets. This raises the obvious question, if anyone can brodcast anything, how secure is the system against malicious actors?\n\nThe answer often turned to, and used in C-ITS, is a Public Key Infrastructure. Many are familiar with the WebPKI for HTTPS, based on the ITU-T's X.509 standards; C-ITS opts instead for its own PKI, an adaptation of the American IEEE's Wireless Access in Vehicular Environments (WAVE) with modifications for the European market.\n\nThis talk with cover the PKI of C-ITS in detail, some of the good and bad decisions made in the stardard, how secure is it in practice as deployed, and how you (yes, you!) can get your own root CA on the EU's Certificate Trust List.\n\nLicensed to the public under https://creativecommons.org/licenses/by/4.0/","original_language":"eng","persons":["Q Misell"],"view_count":28,"promoted":false,"date":"2026-10-30T22:15:00.000+01:00","release_date":"2026-11-05T00:00:00.000+01:00","updated_at":"2026-11-06T03:45:03.861+01:00","tags":["105","2026","dhcp26","D002 Vortragsraum","dhcp26-eng","Day 1"],"length":1565,"duration":1565,"thumb_url":"https://static.media.ccc.de/media/events/dhcp/2026/105-0d61e9d0-6ef4-572b-9349-e98540168aa0.jpg","poster_url":"https://static.media.ccc.de/media/events/dhcp/2026/105-0d61e9d0-6ef4-572b-9349-e98540168aa0_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/dhcp/2026/105-0d61e9d0-6ef4-572b-9349-e98540168aa0.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/dhcp/2026/105-0d61e9d0-6ef4-572b-9349-e98540168aa0.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/dhcp26-105-all-cars-are-broadcasting-die-public-key-infrastruktur-der-daten-autobahnen","url":"https://api.media.ccc.de/public/events/0d61e9d0-6ef4-572b-9349-e98540168aa0","conference_title":"Die Heilbronner Chaos Party 2026","conference_url":"https://api.media.ccc.de/public/conferences/dhcp26","related":[]},{"guid":"3820e624-9db2-50fd-b616-311fac4c24a0","title":"DHCP RELEASE (Closing)","subtitle":null,"slug":"dhcp26-115-dhcp-release-closing-","link":"https://talks.dhcp.cfhn.it/dhcp26/talk/7YHGWG/","description":"Closing the DHCP26.
