A problem with a c'punk-style encrypted fs with source code and wide distribution is, of course, that attackers will KNOW that there is a duress key.
Good point. This suggests a design desideratum for any such system should be that the user may choose not to have a duress key, maintaining semi-plausible deniability for those who choose to have one.
Semi-plausible. (See my other reply to this: an attacker could get ahold of the HD and your system, reverse engineer the driver used, to see what you're doing; backups of the encrypted partition in case of destructive measures are helpful ... they could even return your computer to you and take it apart carefully.) The problem with a duress key is that it relies on "security through obscurity". Rob. --- No-frills sig.
