Asynchronous Ratcheting Tree: Group Messaging with Strong Security Guarantees
- jchrisa 8y agoThe paper makes the Diffie-Hellman tree they use pretty easy to grok: https://eprint.iacr.org/2017/666.pdf https://eprint.iacr.org/2017/666.pdf
- kiwidrew 8y agoFor those interested in ART, there is an IETF working group attempting to standardise it as the "Messaging Layer Security" protocol. Their website [1] has a draft protocol document [2] which explains the ART scheme from a concrete engineering perspective, which I find easier to follow than the original ART paper.
