Exploits weaknesses in RC4 to mount a chosen-plaintext attack and recover the private key. The vulnerability is similar to the one used to crack WEP, but it targets schemes where the initialisation vector precedes the long term key.

rc4-key-recovery-attacks's Issues

applicability question

Hello,

First of all great work implementing the Klein style attacks in this manner.

Does this style of attack have any applicability to the following scenario, using RC4 to "sign" a nonce?:

3 byte nonce concatenated with 16 byte long term key > RC4 Keystream Generator > 259 bytes keystream output

Discard first 256 bytes of keystream leaving only last 3 bytes "result"

Nonce / Result pairs are only information sent publicly
