Efficient Stream Loss - Tolerant Authentication ( TESLA ) in the Asynchronous Layered Coding ( ALC ) and

This document details the Timed Efficient Stream Loss-Tolerant Authentication (TESLA) packet source authentication and packet integrity verification protocol and its integration within the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) content delivery protocols. This document only considers the authentication/integrity verification of the packets generated by the session’s sender. The authentication and integrity verification of the packets sent by receivers, if any, is out of the scope of this document.
