Wireless hacking - a WiFi hack by cracking WEP
TLDR
A look at common threats, vulnerabilities related with wireless networks, the entire process of cracking WEP (Wired Equivalent Privacy) encryption of WiFi, and the necessity to become familiar with scanning tools to help survey the area and tests to run so as to strengthen the air signals.Abstract:
Wireless Local Area Networks frequently referred to as WLANs or Wi-Fi networks are all the vehemence in recent times. People are installing these in houses, institutions, offices and hotels etc, without any vain. In search of fulfilling the wireless demands, Wi-Fi product vendors and service contributors are exploding up as quickly as possible. Wireless networks offer handiness, mobility, and can even be less expensive to put into practice than wired networks in many cases. With the consumer demand, vendor solutions and industry standards, wireless network technology is factual and is here to stay. But how far this technology is going provide a protected environment in terms of privacy is again an anonymous issue. Realizing the miscellaneous threats and vulnerabilities associated with 802.11-based wireless networks and ethically hacking them to make them more secure is what this paper is all about. On this segment, we'll seize a look at common threats, vulnerabilities related with wireless networks. And also we have discussed the entire process of cracking WEP (Wired Equivalent Privacy) encryption of WiFi, focusing the necessity to become familiar with scanning tools like Cain, NetStumbler, Kismet and MiniStumbler to help survey the area and tests we should run so as to strengthen our air signals.read more

Securing ad hoc networks
Lidong Zhou,Zygmunt J. Haas +1 more
TL;DR: This article takes advantage of the inherent redundancy in ad hoc networks-multiple routes between nodes-to defend routing against denial-of-service attacks and uses replication and new cryptographic schemes to build a highly secure and highly available key management service, which terms the core of this security framework.

Capacity of Ad Hoc wireless networks
TL;DR: The question “Are large ad hoc networks feasible?” reduces to a question about the likely locality of communication in such networks, and it is shown that for total capacity to scale up with network size the average distance between source and destination nodes must remain small as the network grows.

Practical attacks against WEP and WPA
Erik Tews,Martin Beck +1 more
TL;DR: In this article, the authors describe two attacks on IEEE 802.11 based wireless LANs: improved key recovery attack on WEP, which reduces the average number of packets an attacker has to intercept to recover the secret key, and dictionary attack when a weak pre-shared key is used.

Weaknesses in the temporal key hash of WPA
V. Moen,Håvard Raddum,Kjell Hole +2 more
TL;DR: Given a few RC4 packet keys in WPA it is possible to find the Temporal Key (TK) and the Message Integrity Check (MIC) key and this shows that parts of WPA are weak on their own.
