Technical Summary
The TESLA source authentication protocol needs bootstrapping
either via a key management protocol or in-band with a data
encapsulation protocol. The "Bootstrapping TESLA" specification
describes how to do this via the MIKEY protocol. The specification
includes payloads and parameters required for TESLA initialization
between the "source" and each receiver individually.
Working Group Summary
The WG considered whether to include this as part of the SRTP-TESLA
specification and decided against it (rough consensus). The protocol
itself is fairly straightforward. However, it is an important
contribution and other documents describing TESLA bootstrapping
in the context of other protocols (e.g., GKDP) might be developed
in the future.
Protocol Quality
There are several MIKEY implementations and a TESLA implementation;
however, SRTP-TESLA and MIKEY-TESLA extensions have not yet been
implemented (to our knowledge).
