<p><b>New page</b></p><div>By "broadcast scheme", this refers collectively to the peer-to-peer pairwise broadcast, or the "sender keys" optimisation on top of it. I think "broadcast scheme" is too generic and confusing. How about "p2p-broadcast", "full-broadcast", "sender-broadcast", or "member-broadcast"?<br />
