Once upon a time there was the CAT working group whose name was an abbreviation for "Common Authentication Technology". It produced IETF specifications for GSS-API.
It was succeeded by the kitten working group, which has been working on the next-generation GSS-API specifications.
There is now a proposal for a MOGGIES working group, which will work on Mechanisms Of Generating Generically Interoperable & Effective Security.
