Breaking 104 Bit WEP in Less Than 60 Seconds
[chapter]
2007
Lecture Notes in Computer Science
Preserved Fulltext
We demonstrate an active attack on the WEP protocol that is able to recover a 104-bit WEP key using less than 40,000 frames with a success probability of 50%. ...
On a IEEE 802.11g network, the number of frames required can be obtained by re-injection in less than a minute. ...
Breaking implementations using larger WEP keys Some vendors implemented WEP using root keys longer than 104 bit. We have seen implementations using up to 232 bit key length for the root key. ...

In this paper, we describe two attacks on IEEE 802.11 based wireless LANs[2]. ...
The first attack is an improved key recovery attack on WEP, which reduces the average number of packets an attacker has to intercept to recover the secret key. ...
If more than 2 MIC verification failures occur in less than 60 seconds, the communication is shut down, and all keys are renegotiated after a 60 second penalty period. • When a packet has been received ...

Using examples from other papers, we show that RC4 is completely insecure in a common mode of operation which is used in the widely deployed Wired Equivalent Privacy protocol (WEP, which is part of the ...
In this paper we analyze and present some weaknesses and possible attacks on the RC4 stream cipher which were published in many journals. ...
The simplest weakness is the small size of the secret key and the IV: A 40-bit key can be recovered by an exhaustive search in less than one day. ...

It runs in less than 5 seconds on an off-the-shelf PC. Using the same number of packets, Aicrack-ng yields around 3% success rate. ...
Our active attack, based on ARP injection, requires 22 500 packets to gain success probability of 50% against a 104-bit WEP key, using Aircrack-ng in non-interactive mode. ...
We show that we can recover a 104-bit long WEP key using 22 500 packets in less than 5 seconds using an off-the-shelf PC. With less number of packets, the attack will run for a longer period. ...
