In article <1cl5stINN4qc@function.mps.ohio-state.edu> fiedorow@function.mps.ohio-state.edu (Zbigniew Fiedorowicz) writes: As has been pointed out here, Prof. Denning's proposal has some minor flaws: malefactors might encrypt their nefarious missives with their own unauthorized crypto systems before encrypting them with the approved registered keys. To address this issue I propose a slight modification of Prof. Denning's scheme. Since the Trustworthy Independent Agency (TIA) will have all the necessary keys, it might as well perform the actual encryption as an additional service at little extra cost. [...] Hm. Time for open codes (bury the real plaintext inside one of a large stock of innocuous-looking letters), at least for bursty traffic ... besides, the TIA would have to be able to recognize file attachments (graphics, sound files, programs, ...) or did you think ASCII was forever? And then there are "free" media like "pirate" radio -- voice scramblers could get stronger -- and so on -- I think the cat is out of the bag right now. -- Craig Presson
