There's a lot of stuff in the literature on this subject. This sort of behavior is usually called ORCON, for "ORiginator CONtrolled" -- referring usually to intelligence so sensitive the source controls who sees the intel and how it is used. The first paper I can find on this subject belongs to Graubert, "On the Need for a Third Form of Access Control," _Proceedings of the 12th National Computer Security Conference_. It's worth reading. _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
