Re: security requirements


it's good to shed some light on the history and how it came all into  

I think we all can agree that a suitable MTI security in HTTP would  
be a good thing. The problem is that current analysis by several  
people indicates that there is not such authentication scheme  
available right now. If it would, the debate could start which  
process to use in what spec and protocol revision that could best be  

But the current approach seems to talk about processes and barriers  
to spec revisions before that technical solution even has surfaced.  
Spec writers, putting often their spare time into this, feel  
frustrated. It seems that they either have to include some mumbo- 
jumbo into their spec which not everyone implementing the  spec is  
able to follow or shall fix the whole HTTP MTI security issue.

I feel this is wasting energy on both sides without giving any  
tangible results.
