Re: [OAUTH-WG] OAuth 1.0a

Hi Bill, 

how do you know that the outcome of the security discussions will unlikely be different than MAC?

The views about TLS had changed in the meanwhile (a few years ago many thought it is too heavy and too expensive to get certificates), and we now have the JSON work as well. On top of that we may also want to provide not just client to server key confirmation with integrity protection of a few fields but more than that. In a nutshell the solution has to provide better security than bearer -- not just be different. 

Ciao

HoK is interesting, but I've become convinced that it's not actually anything that needs it's own spec, you can do HoK with MAC or any other signed scheme by including the needed proof of ownership in the token.   HoK, however it works out, is unlikely to vary a lot from the elements that would currently be needed to support MAC or 1.0a and if needed can just extend the SASL mechanism.
