Using the Fluhrer, Mantin, and Shamir Attack to Break WEP
We implemented an attack against WEP, the link-layer security protocol for 802.11 networks. The attack was described in a recent paper by Fluhrer, Mantin, and Shamir. With our implementation, and permission of the network administrator, we were able to recover the 128 bit secret key used in a production network, with a passive attack. The WEP standard uses RC4 IVs improperly, and the attack exp...
متن کاملStatistical Attack on RC4 - Distinguishing WPA
In this paper we construct several tools for manipulating pools of biases in the analysis of RC4. Then, we show that optimized strategies can break WEP based on 4000 packets by assuming that the first bytes of plaintext are known for each packet. We describe similar attacks for WPA. Firstly, we describe a distinguisher for WPA of complexity 243 and advantage 0.5 which uses 240 packets. Then, ba...
متن کاملSocial Security beneficiaries affected by the Windfall Elimination Provision in 2006.
The Windfall Elimination Provision (WEP) is an alternative method of computing benefits for some workers who receive a pension based on work not covered by Social Security. The WEP computation results in a lower benefit than the worker would receive under the regular computation method. This article provides a brief legislative history, describes the WEP computation and applicability, and prese...
متن کاملStatistical and Algebraic Cryptanalysis of Lightweight and Ultra-Lightweight Symmetric Primitives
Symmetric cryptographic primitives such as block and stream ciphers are the building blocks in many cryptographic protocols. Having such blocks which provide provable security against various types of attacks is often hard. On the other hand, if possible, such designs are often too costly to be implemented and are usually ignored by practitioners. Moreover, in RFID protocols or sensor networks,...
متن کاملAnalysis of WEP Performance on Mobile Devices
Mobile devices are becoming more popular every day; they must keep up with security implemented by desktop computers. This paper tries to evaluate performance of data transmission with and without ciphering techniques. WEP is not the best way of securing a network but it is widely used, that is why we used WEP on these tests. This article tries to define how much performance is lost with WEP, s...
