Why WPA-PSK do not uses Diffie-Hellman key exchange? Michael already suggested a method that provides stronger security: A Diffie-Hellman exchange. This would require an attacker to actively perform a man-in-the-middle-attack, as opposed to starting Wireshark and entering the PSK. I'm also wondering why they didn't implement it like that. |

Is semantic security important in a hybrid cryptosystem? Your're right, that was a typo - I meant random plaintext as input to the asymmetric cipher. I've changed the question accordingly. Thanks! |

Does TLS use RC4-drop[n]? Now it makes sense, thanks again. I was confused by RFC 4345 mentioning the possibility of recovering the key from the first keystream output bytes, but now I think they probably just want to be on the safe side and are not referring to actual attacks in that paragraph. |

Does TLS use RC4-drop[n]? Thanks, that pretty much answers my question. Just to make sure, regarding the second issue: There is no (known) way to derive the RC4 key from a single keystream alone, right? So even when the very first thing that is sent in a RC4 encrypted connection is gigabytes of known plaintext (zeroes, for example), the key cannot be easily recovered? (Assuming that the initial key has never been used before, even partially - unlike WEP etc.) |
