Reducing IETF Meeting Scheduling Conflicts
With many IETF participants active across a number of active working groups and limited time slots in an IETF meeting week, we aim to arrange sessions in the agenda to minimize conflicts that prevent participants from joining sessions that are of interest to them. In each post-meeting survey we ask meeting participants to comment on the scheduling conflicts they experienced in the meeting agenda and we then use this information to improve the meeting agenda.
31 Mar 2023Messaging Layer Security: Secure and Usable End-to-End Encryption
The IETF has approved publication of Messaging Layer Security (MLS), a new standard for end-to-end security that will make it easy for apps to provide the highest level of security to their users. End-to-end encryption is an increasingly important security feature in Internet applications. It keeps users’ information safe even if the cloud service they’re using has been breached.
