Randomized stream cipher using multivariant quadratic equations @Thomas - no, sorry, the streams can be published publicly with the cipher-text. I try to depend on MQ to make sure that even with the streams being public knowledge, the key can not be computed. |

Randomized stream cipher using multivariant quadratic equations Yeah, step two is a bit handwavey and is probably where the security is made or lost. You'd need to prove that step 2 really defines a difficult set of equations in the average case. My question is whether I've generally misunderstood the underlying problem or whether I've broadly got it right and that this would actually work if all the details were ironed out? |

HRNG for One Time Pad @CodesInChaos - yeah, I know how a universal hash works. I'm wondering how one does it without burning at least another message's worth of pad material? |

HRNG for One Time Pad @poncho: Any pointers to how this might be done? A reference to a paper or book reference would be fine - just interested in a more efficient way to do it? |

How is the EAX-mode used in EAP-PSK (RFC 4764)? poor title spelling |
