The Use of Timed Efficient Stream Loss-Tolerant Authentication (TESLA) in IPsec

This document specifies the use of Timed Efficient Stream Loss- tolerant Authentication (TESLA) -- a source authentication mechanism for multicast or broadcast data streams -- with IPsec ESP. In addition to the source authentication using TESLA, group authentication of the ESP packet can be provided using a shared symmetric group key. Thus, the proposed extension to ESP combines group secrecy, group authentication, and source authentication transforms in an ESP packet.
