-
- The CCITT committee responsible for V.42 and V.42bis (error correction
- and compression standards for modems) has also said that one of the items
- on their agenda (V.42ter?) may be standard encryption for modems. This
- makes a good deal of sense, especially for compressing modems (it works
- *much* better for both purposes to encrypt after compression rather than
- vice versa). The DSPs or control processors could probably find the
- spare cycles easily enough. Presumably, you would send the key to the
- modem "out of band", and it would do the encryption/decryption on the fly,
- after compression/before decompression. Kind of a neat idea.
-
- I doubt they would use DES, because of the restrictions on international
- use (CCITT produces international standards). IDEA (IPES) might be an
- option. Or something else. We are talking about single key encryption
- here, not public key systems (most likely).
-
- Then again, nothing may ever come from this; certain governments may
- quash the idea. A US government proposal (before the more recent FBI
- universal multimedia remote wiretapping one, but sure to resurface) has
- already been made (thankfully losing the first round), to require that
- all encryption devices have a "back door" for the government ("under
- court order" of course); no encryption device without that would be
- legal.
-
- I don't think they would like the idea of standardized mass-produced
- modems with built in serious encryption, with no back door. And other
- folks would not want to pay for any encryption WITH a back door. So
- the modem standards folks may be forced to indefinitely table this.
-
- (Or produce a standard which can be used in Europe but not imported
- to the US; while this has surreal attractions for highlighting the
- absurdity of it all, it would probably have marketing liabilities :-)
