DM-Steg: New steganographic encryption module
I'd like to introduce DM-Steg. It's a device mapper module that provides deniable/steganographic encryption. DM-Steg provides similar capabilities to Rubberhose (a now defunct project by Julian Assange et al.) and more advanced deniable encryption than Truecrypt.
DM-Steg can be used to hide any number of strongly encrypted volumes inside block devices or files. There is no way to determine how many volumes a block device contains or even if the block device is not random data. DM-Steg uses strong encryption yet still achives goood performance - up to 148 MB/s on my core 2 duo, and only 1% slowdown on kernel compiles.
DM-Steg is working code and free software, so if you have any interest in deniable encryption, please head over to http://dmsteg.sf.net and grab the tarball!
I've taken this project as far as I want so I'd very much like it if there's anyone in the OSS community who wants to take it further. Don't be shy! :)
All the best,
