IEEE S&P posted its registration instructions and fees at https://na.eventscloud.com/ereg/index.php?eventid=782083&
Discount registration rates are available until April 21, 2024, 11:59 pm PDT.
This year IEEE does not offer virtual registration options, as the conference and the workshops are meant to return to their traditional in-person mode.
You have the option of registering for the LangSec workshop only. Choose "Security and Privacy Workshop" in the multi-step registration form to do so, and leave the "Symposium on Security and Privacy" unchecked.
Please refer to https://sp2024.ieee-security.org for more information.
