Internet Engineering Task Force (IETF) V. Roca Request for Comments: 6584 INRIA Category: Standards Track April 2012 ISSN: 2070-1721 Simple Authentication Schemes for the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) Protocols Abstract This document introduces four schemes that provide per-packet authentication, integrity, and anti-replay services in the context of the Asynchronous Layered Coding (ALC) and NACK-Oriented Reliable Multicast (NORM) protocols. The first scheme is based on RSA Digital Signatures. The second scheme relies on the Elliptic Curve Digital Signature Algorithm (ECDSA). The third scheme relies on a Group- keyed Message Authentication Code (MAC). Finally, the fourth scheme merges the Digital Signature and group schemes. These schemes have different target use cases, and they do not all provide the same service. Status of This Memo This is an Internet Standards Track document.
