Peer-to-Peer Security for Mobile Real-Time Communications with ZRTP

Pure peer-to-peer communication, such as voice over IP (VoIP), cannot rely on third parties on security. ZRTP is a solution for real-time peer-to-peer communication security problems, relying on Diffie-Hellman key exchange and short authentication strings (SAS). The demonstration shows how ZRTP is used with mobile phones, with only minor changes to the normal phone UI.
