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.
