"Multicast Extensions to the Security Architecture for the Internet Protocol", Brian Weis, George Gross, Dragan Ignjatic, 6-Jun-08. ( bytes)

The Security Architecture for the Internet Protocol describes security services for traffic at the IP layer. That architecture primarily defines services for Internet Protocol (IP) unicast packets. This document describes how the IPsec security services are applied to IP multicast packets. These extensions are relevant only for an IPsec implementation that supports multicast.

"Use of TESLA in the ALC and NORM Protocols", Vincent Roca, Aurelien Francillon, Sebastien Faurite, 30-Jul-08. ( bytes)

This document details the TESLA packet source authentication and packet integrity verification protocol and its integration within the ALC and 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.

"Using Counter Modes with Encapsulating Security Payload (ESP) and Authentication Header (AH) to Protect Group Traffic", David McGrew, Brian Weis, 9-Jun-08. ( bytes)

Advanced Encryption Standard (AES) counter modes use a counter, which is typically assumed to be incremented by a single sender. This memo describes the use of AES counter modes when applied to the Encapsulating Security Payload (ESP) and Authentication Header (AH) in multiple-sender group applications.
