I'm a cryptographer, a former Pay-TV industry worker bee, and I currently work as a professor of information security in a university of applied sciences somewhere in the french-speaking part of Switzerland.

My main scientific interests are related to cryptography and cryptanalysis, (especially to the design and cryptanalysis of symmetrical cryptographic primitives), industrial cryptography, resistance to grey- and white-box adversaries, software security, OS security and ethical hacking.

comment How to efficiently generate a stream of independent, but biased random bits?
Hi Paul! Many thanks for your answer ! My scenario is somewhat very-high-speed and hardware-contrived :-) More to come ...

comment What do the magic numbers 0x5c and 0x36 in the opad/ipad calc in HMAC do?
Obviously, using a single constant would have fitted the security proof; I don't know why they chose two.

comment How to efficiently generate a stream of independent, but biased random bits?
Using a TRNG or a CPRNG for the initial source of randomness is out of scope for my question. Thank you for your proposal. Still, you decimate the initial source by a factor of two, while we could expect to ... expand the throughput in the best case!
