I would guess that all efforts towards creating secure, encrypted email would only cause surveillance groups to focus their efforts more upon what's showing up on your screen in plaintext before encryption and
To do that, they need to know who you are and where you are located. They can't bug everyone. If a pseudonymous system is used, then it would be your top priority to make it impossible to connect your pseudonym with your legal identity. If you have not already, read Vinge's _True_Names_. If "they" know who you are and where you are located, many techniques are available, TEMPEST eavesdropping being only one of them. Others are confiscating your equipment, arresting you, threatening you and using you to track down other people. So, instead of concentrating on how to shield yourself from surveilannce once you have been found, concentrate instead on not being found. You can maintain a usual identity that you use for normal conversation, but for anything dangerous use an alternate identity, secure remailers, etc. You might want SOME shielding, in case "they" take up the practice of routinely driving up and down the streets looking to randomly find something (someone) interesting. It should be much easier to protect against a casual search. It may be nearly impossible, and/or useless to protect oneself from a determined physical attack by a resourceful enemy. It is much more profitable to prevent the attack. -- Yanek Martinson mthvax.cs.miami.edu!safe0!yanek uunet!medexam!yanek this address preferred -->> yanek@novavax.nova.edu <<-- this address preferred Phone (305) 765-6300 daytime FAX: (305) 765-6708 1321 N 65 Way/Hollywood (305) 963-1931 evenings (305) 981-9812 Florida, 33024-5819 (not in hiding yet :-)
