I'm not sure how much you want to know, but it is statistical procedure. Because of the small size of the IV's (24 bit), their only about 6000 possibilities. If you capture enough IV's, you can use statistical techniques to determine the underlying key very quickly.


thank you OTW,

sending ARP packets the station will reply with ARP reply packet.but the information is encrypted.but we know what the ARP packet contains(192.168.. is at 11:22:33:*:*:*). With the ciphertext and the data the password can be cracked.But the password is mixed with IV. capturing enough IVs we ca get the original password.

Am I right?

I am using aircrack-ng,but it does not shows the interface. so please help me what to do ???

More information needed. I hate to drag a post out, but you give me no bones to pick through.

  • Show me your command for aircrack-ng!
  • What are you trying to do?
  • Ever seen and/or used Linux before?
