Hello folks, I'd like to introduce DM-Steg. It's a Linux 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. Without keys, there is no way for an attacker to determine how many volumes a block device contains or even if the block device is not simply 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. For those interested in the mechanics of DM-Steg, the .pdf file on the site should provide a good overview. 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, - Leo _______________________________________________ cryptography mailing list cryptography@randombit.net http://lists.randombit.net/mailman/listinfo/cryptography ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
