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 Dmitri Vitaliev -- Director | https://equalit.ie | https://deflect.ca GPG key ID: 0x6FF1895D
