Hi, the on-line LUKS documentation recommends for crypto-analytic reasons to initialize any partition that is to becom encrypted by LUKS to be initialized with random data (from: http://www.saout.de/tikiwiki/tiki-index.php? page=EncryptedDeviceUsingLUKS): Note : if you want your encryption to defeat a full cryptoanalytic attack, not just casual snooping, you need to fill the disk with high quality random data. Badblocks below justs uses 'libc' random(), but is fast (your limitation will be disk speed, not CPU speed). /dev/urandom is better (takes about 5 minutes per gigabyte on my system), /dev/random is best (takes about 1 year per gigabyte on my system, much too slow!). What's the very reason for it (besides eliminating any left-over plaintext data)? Is there any scientific papaer or reference backing this up?
