# SPAC (Secure Privacy, Authenticity, and Confidentiality)

A 79-slide deck, subtitled 'Privacy Given Strongest Authenticity and Confidentiality', that presents the SPAC white paper: the PAC theorem, the three-party exploitation model, ESSR-based authenticated encryption, relationship and intermediary protocols, sustainable privacy and threat mitigations. It is for readers who want the SPAC argument in slides before the long paper.
