Despite the article's premise that it doesn't matter how many layers of encryption, etc are used to protect e-mail, it is all discoverable. Now, I'm not a lawyer, but my understanding of current US law is that the TEXT of any e-mail is discoverable: if the sender encrypted it, there is no current law on the books that would force surrender of the key. This changes a bit if only the servers encrypt the data -- which is a strong argument for public use of encryption.
On a side note, however, it is important to realize that if the authorities wish to take the time to track down the senders and recievers of e-mail messages, the plaintexts of even encrypted messages can be subpoenaed (sp?), so caution in what is said is still important.
This brings up one last issue, too: with the revision of Yahoo!'s ToS to state that they own all IP expressed over thier services, even instant messaging logs could be subject to this kind of discovery. Write your congressperson, as per usual...
In the meanwhile, encrypt, encrypt, encrypt! At least we'll make them work for the data. :)

I completely understand what you're saying here because I've been involved in similar situations, but the part that I don't understand about this is that people don't really seem to understand that you don't have any control over the email that people send you.
I know that people think that you do, but why can't companies understand that you are going to get spam occationally and you're going to get junk mail.

Woah. I think you might be on to something here.
I'm not a crypto guru. I barely understand public key encryption as it is, but here goes:
What if an encryption scheme were devised where the plaintext is encrypted with two or more pivate keys (belonging to one person), plus the other key. The encrypted would decrypt to two or more different texts, depending which key is used.
So, I could encrypt "Meet me at midnight." and "Happy birthday, Ed." With two keys, into one block of encrypted text. Then, if I use my private key A, it returns "Meet me at midnight." and if I use my private key B, it returns "Happy birthday, Ed."
If we could somehow make the number of original plaintexts undetectable, could supply keys to those who demand them, where they would decrypt our code to get "Happy birthday, Ed." when the REAL secret was "Meet me at midnight."
I know I could've worded that better, but is this a possibility? Is it already being done? I know it's a little along the lines of Steganography [tripod.com], where the encrypted text is inserted into a piece of digital media, making it look less like an encrypted message.
Summary:
If we could encode, say, 4 strings into one crypto block, and have it return different unencrypted text for 4 different keys, while keeping the number of original strings undeterminable, the party decyphering the string would never know if they have ALL of they keys, thus they would never know if they have the data that the sending party doesn't want them to see.

This reminds me of the ACC and Gentry Lee's book "Rama II". In it, three military officers on a spacecraft have 50 digit numeric codes to arm the ship's nuclear bombs. The entry of any two of the officers' sequences activates the bombs, so the system is defended against the actions of either a single rogue officer or a stubborn one. The scheme is called Trinity.
During the spaceflight, one of the officers dies in surgery. Near the end of the book, the two remaining officers are ordered by Earth to activate the bombs for a time-delay, set them down inside a giant spacecraft that's about to crash into Earth, and leave in their own exploration ship.
Anyway, the 50-digit string that one of the officers had was a mathematical sequence that he didn't actually remember, but he knew how to work out. I don't have the book handy, but it was some kind of obscure theorem that the authors described. It's an interesting way to generate a password for when you're shipping a HD across the country or something similiar.

While ordinarily medical information is considered private, by the time my hard disk has been unerased, that won't prevent the information from being leaked.
Robbing people of their privacy has a chilling effect on legal expressions of non-mainstream viewpoints, whether they are political, ethnic, religious, scientific or otherwise. If you can't discuss those views with people of like minds in harmless ways without having every word exposed to your neighbors and coworkers, won't you think twice about talking at all?

(I don't think this is a spoiler, but if you haven't read the book, proceed at your own risk.)
At one point the bad guys want a particular piece of information that they are pretty sure resides on our hero's mail server. So, in order to get it they jimmy up a lawsuit and subpoena the mail server.
Returning to the real world, I don't think that this is a particularly stunning revelation; people have been aware of these issues surrounding paper documents for a long time. The only difference is that we are accustomed to thinking of email as a more informal medium than paper. Apparently the courts don't agree. Just follow the same policy with confidential email that you follow for confidential paper documents, and you should be all right.

I'd presume the keys are backed up, however...
Then there's a few that offer one-shot sends (can't reply to these) that delete all traces of the message from their servers.... just not from the recipient's machine...
The best solution is to take the advice of the article. Use harshly separated accounts, do what you can to (hard)delete files regularly, etc.
I'd recommend setting up an alternate personality or three that you access only via anonymous proxy(s) that offer encryption (hushmail, ynnmail, the various anonymous remailers). Use the PGP plugin's secureviewer if you're truley paranoid to defend against Tempest attacks... and for chrissakes, clear out your cookies, temporary internet files, and temp dirs regularly and do a 11-time rewrite of the emptied space.

It'll cost you a packet if you do get subpoena'd, BTW, in any case; my understanding is that you have to pay the upfront costs of providing the documents. I don't know if you get them back if the other guy loses at the end of the day, but still, if you have to pick through years worth of backup tapes extracting e-mails from (say) a proprietary, database-type system, it will cost you lots.

I'm in no way saying "Encryption is for the birds, why bother". I'm saying that in many cases it's not feasible to encrypt every single piece of mail (esp. to those who'd have no clue as to decrypt it), and chances are, those "little" things are the ones that's going to come back to you.
A recent experience (Score:3)
I work for a large government agency where all email is saved forever because everyone is accountable for everything they do for all time. That's fine. We're public sector law enforcement; we should have such rules. Recently, though, an employee sued the agency and requested all email files. Our lawyers argued that such a subpoena would be overbroad and would reveal a great many private things shouldn't be made public. The judge agreed and a compromise was worked out. Several years worth of Microsoft Exchange backup tapes were sequentially reloaded on a system set up for the purpose. Each time a tape was restored, all files were searched for a text string matching the name of the woman who brought the suit. Then, all emails that contained her name were *printed out* and delivered to her lawyers. Not surprisingly, lots of folks had been jabbering about this woman in email, so there were boxes and boxes of printouts. It took the poor admin assigned the task literally weeks to complete, but at least there was no way for all sorts of extraneous data to go public.
Contrast that situation with the situation of the airline employees who found their computers seized. Were they entirely without recourse? Were they not given a chance to produce the documents without having to turn over their hardware? I don't know, but I do know that if such a thing happened to me, I'd be less than happy. I have lots conventionally encrypted files that are relatively safe since the only copy of the password is in my head. But would I be willing to sit out a contempt citation to protect that data? Talk about feeling conflicted!!
Short side note: There are a zillion different circumstances when testimony *can* be compelled. I'm surprised by the number of posters who don't understand that 5th amendment protections are often non-existent, especially in civil actions. They can even be circumvented in criminal actions rather easily, assuming you aren't the primary target of the prosecution. I guess high school civics classes aren't what they used to be.
IANAL, of course.

On another note, this wouldn't matter anyway in this case. The 5th amendment only applies to criminal cases. A lawsuit is a civil case, so the protection of the 5th doesn't apply.
Re:What if you delete or have "misplaced" it. (Score:2)
I am currently re-reading Cryptonomicon, and I recently came across the bit (about a third of the way through) where Randy and Eb discuss something like this, and I've been thinking about it some more. How does this sound:
In addition to encrypting your real messages, you have your systems set up to send fake messages consisting of random garbage to each other at random intervals. Hence, no monitoring of server logs, or even physical sniffing of transmissions, can prove that a message was ever sent.
That was Eb's idea, but they didn't go further into it. Here's my addition: The problem is that they can still require you to surrender your keys, and when you do, they can see which messages decrypt to meaningful text and which are garbage. However, suppose each person actually has two keys, called, say, the major key and minor key. The minor key is the one that you use publicly, and everything about the major key, including its very existence, is kept secret.
You send messages back and forth using the minor keys when the content is not particularly important (important enough to encrypt normally, but not damaging should it come out in discovery), and use the major key for the things that you really don't want to have discovered. When sub-poenaed to surrender your messages, you surrender your minor key, and explain that, to protect against information leakage, you have been chaffing your communications with garbage and that decrypting all the messages with this key will reveal which ones were real and which were chaff.
What they don't know, and couldn't prove even if they suspected it, is that the set of messages that decrypt to gibberish are further subdivided into the actual garbage and the important messages that were encrypted with the major key. The main point is that you have a plausible explanation for the existence of observed transmissions that cannot be decrypted, so they have no real choice but to believe you when you deny the existence of any other messages.

Business e-mail is a completely different thing. A court order to view *corpotate* mail is definitely OK. Wether or not they can "prove" anything.
People will just have to learn to separate their personal and professonal e-mails. Perhaps companies should insist on digital signatures on business mail, informing employees that business mail is company property.
STOP Hold the flame thrower! Of course, they ought to provide a semi-private mail account too, for company (or personal) mattter "off the record".

Yes, but that's for criminal cases, and it covers only the defendant. You cannot use that for a civil case, nor can use "plead the fifth" if you are a witness. In the cited case, Netscape vs Microsoft, the fifth amendment didn't play a role.

Take a look at the example case, Netscape vs Microsoft. Should Netscape argue in front of the judge that the copies of the emails found on the disks of *Netscape* employees were forged by Microsoft? Of course, Microsoft also had to forge the logs in all the servers where the email passed through. And boy, they started early with this forgery, as the backup tapes have those emails as well!

Doctors are subject to the law. And the law even says doctors *have to* protect the privacy of the patients. However, that doesn't mean they can keep quiet when there's a court order. Only priests can refuse to talk without being penalized.
Many of us sysadmins feel this way, I think we have to be serious about it.
In that case, it's easy for you. Next time you get a court order to open your logfiles, refuse. If you think your code of honour superceedes the law, you shouldn't have a problem dealing with the consequences.
