What tools can be used to make truly deniable encryption? Suppose, authorities can use any force to make you open your passwords.
Truecrypt can have only one hidden container, which means that authorities will not stop, until you reveal this second password, even if you did not create hidden container.
So, is there any way to create many hidden containers, so that authorities could not even tell how many passwords they should beat out of you. And it is desirable that this way should be secure enough against other, more intelligent decryption methods like statistical analysis of used clusters and so on.
Here http://en.wikipedia.org/wiki/Deniable_encryption i've found info about rubberhose, but it is not maintained since 2000, so i dont know how much it is reliable.
Another way I found is to write to hard disk with different offsets using for example similar scripts http://sourceforge.net/projects/stlth/files/
But this way, as far as i understand, data is not mixed physically, so it is vulnerable to that smart statistics methods. I.e. if authorities see that you heavily used the part of drive that is not revealed using passwords you already gave then they continue to try to get the passwords. Rubberhose, accorging to documentation, has protection against these methods, but the project is too old.
What another tools could you advise to make several hidden containers on disk?
