RFC 4442: Bootstrapping Timed Efficient Stream Loss-Tolerant Authentication (TESLA), S. Fries, H. Tschofenig2006-03-01T23:00:00-00:00This document specifies payloads for the Multimedia Internet Keying (MIKEY) protocol for bootstrapping TESLA for source authentication of secure group communications using SRTP.
