Title: Recall Packet Approach to Data Source Authentication for Multicast Security
State: Active
Authors: Atul Sharma

Data source authentication is an important requirement to provide multicast
security. Data source authentication assures that the member claiming to
send the data is the actual sender. An imposter member should not be able
to claim to be the sender of the data. This document proposes a scheme by
which data source authentication can be acheived. The idea is to instead of
digitally signing the data packets, a digitally signed recall packet on
detection of an imposter transmission. The data packets are sent using
symmetric MAC authentication.
