2 Weaknesses and Strengths Analysis over Wireless Network Security Standards
Authors: Daniel Padilla, Edward Guillen
Abstract:
Several wireless networks security standards have been proposed and widely implemented in both business and home environments in order to protect the network from unauthorized access. However, the implementation of such standards is usually achieved by network administrators without even knowing the standards- weaknesses and strengths. The intention of this paper is to evaluate and analyze the impact over the network-s security due to the implementation of the wireless networks security standards WEP, WPA and WLAN 802.1X.
Keywords: 802.1X, vulnerabilities analysis, WEP, wireless security, WPA.

Authors: Lae Lae Khine
Abstract:
RC4 was used as an encryption algorithm in WEP(Wired Equivalent Privacy) protocol that is a standardized for 802.11 wireless network. A few attacks followed, indicating certain weakness in the design. In this paper, we proposed a new variant of RC4 stream cipher. The new version of the cipher does not only appear to be more secure, but its keystream also has large period, large complexity and good statistical properties.
Keywords: Cryptography, New variant, RC4, Stream Cipher.
