Mprotect() to keep stray pointers out. Obfuscate data kept in that memory. You can do a lot in software and in practice that might be enough. In theory, true security can only be achieved through hardware based security modules-atleast thats what I feel, others might disagree. Paranoid

Re: [cryptography] urandom vs random

I think the programs block when reading from random, if the kernel doesnt have enough entropy. When reading from urandom, that is not the case. Basically the internal pool is reused to generate pseudo random bits so that the call doesnt need to block. As far as I know, there is no measure like 50
