Internet Standards Almanac
Messaging Layer Security | MLS
MLS aims to develop a standard messaging security protocol for user communication, particularly in group chats. Standardising security protocols for group chats can increase the security and privacy of online communications and prevent malicious actors from tampering or eavesdropping on an individual’s messages. While the group’s aim is not for interoperable platforms, their work lays the potential for interoperability in messaging between platforms.
- Standard under development: The MLS protocol was submitted in September 2022 to the Internet Engineering Steering Group (IESG) for technical review and approval to become an IETF standard. This will be an open standard that can be adopted by various communication platforms to increase user security and privacy in group chats.
