A white paper, in Markdown on GitHub, that sets out the PAC (privacy, authenticity, confidentiality) trilemma and designs messaging protocols that give the best privacy possible given the strongest authenticity and confidentiality, using KERI autonomic identifiers and a modified ESSR (Encrypt Sender, Sign Receiver) construction. It covers threat models, relationship formation, intermediaries, interaction contexts and a CESR encoding, and is aimed at protocol designers.
