 Dear Libtech

In recognition and celebration of Human Rights Day, eQualit.ie is proud to
release the first public draft of a provably secure protocol for group
messaging on the Internet https://learn.equalit.ie/wiki/Np1sec

The protocol provides for end­-to­-end security of synchronous
communications between any number of people. It is efficient and builds on
recent advancements in cryptographic research. Security properties of
(n+1)sec include:

* Confidentiality: the conversation is not readable to an outsider
* Forward secrecy: conversation history remains unreadable to an outsider
even if participants’ encryption keys are compromised
* Deniable authentication: Nobody can prove your participation in a chat
* Authorship: A message recipient can be assured of the sender’s
authenticity even if other participants in the room try to impersonate the
sender
* Room consistency: Group chat participants are confident that they are in
the same room
* Transcript consistency:  Group chat participants are confident that they
are seeing the same sequence of messages

The protocol is being implemented as a FLOSS libpurple plugin and will find
its first home in crypto.cat. We anticipate wide adoption in other instant
messaging platforms. Contact us and join the conversation on the wiki
https://learn.equalit.ie/wiki/Talk:Np1sec and check out the early code on
https://github.com/equalitie/np1sec
