Hi all,
I would like to use a type of Merkle Hash Trees for verifying the
integrity
of a live stream delivered using an application level multicast
distribution
tree.
I found a bunch of academic work related to this topic under the
keyword "multicast data origin authentication". Several of the
proposed techniques use hash chaining.

It may also be worth using ECC instead of RSA/DSA to sign the Merkle
tree roots for better performance.
I haven't heard of any P2P systems that use such techniques, so good
luck.
