We are in advanced world of internet with new technologies in these days. So many new wireless networks technologies have been emerged. WiMAX and WLAN are such wireless technologies which are being adopted by most of the users. WiMax is one of the advanced technologies from those. Due to advancement, the security related issues has also been increased. Security has become one of the challenging...

—Many of the WLAN hotspots are significant in size and achieving good coverage may be challenging. The current standard for providing coverage is to distribute individual WLAN access points in the target area. Due to the fact that the in-building environment has many challenges, such as walls and elevators, the number of access points needed by using this method may become significant. There ar...

The SMS4 block cipher is part of the Chinese WAPI wireless standard. This paper describes the specification and offers a specification for a toy version called simplified SMS4 (S-SMS4). We explore algebraic attacks on SMS4 and S-SMS4 using Gröbner basis attacks on equation systems over GF(2) and GF(2), as well as attacks using a SAT solver derived from the GF(2) model. A comparison of SAT and G...

in block cipher SMS4 Zhang MeiLing, Liu JingMei, Wang XinMei National Key Lab. of Integrated Service Networks, Xidian University. Xi’an, 710071,China Abstract: SMS4 is a 128-bit block cipher with a 128-bit user key and 32 rounds, which is used in the Chinese National Standard for Wireless LAN WAPI. In this paper, all possible differential patterns are divided into several sections by six design...

SMS4 is a 128-bit block cipher used in the WAPI standard for wireless networks in China. In this paper, we analyze the security of SMS4 block cipher against differential cryptanalysis. Firstly, we prove three theorems and one corollary that reflect relationships of 5and 6round SMS4. Nextly, by these relationships, we clarify the minimum number of differentially active S-boxes in 6-, 7and 12-rou...

The approval by the IEEE of the 802.11 Standard for wireless LANs has given the WLAN industry a needed boost. Manufacturers of WLAN systems are now cooperating in performing interoperability testing. Such testing is providing assurance that 802.11 compliant equipment purchased from one manufacturer will interoperate with 802.11 radios manufactured by other OEMs. This is an important considerati...

Wireless Local Area Networks (WLANs) provide many significant advantages to the contemporary business enterprise. WLANs also provide considerable security challenges for network administrators and users. Data confidentiality (ie, unauthorised access to data) breaches are the major security vulnerability within WLANs. To date, the major IT security standards from the International Standards Orga...

WLAN-based location systems are implemented in indoor location service in recent years. These systems suffer largely from the signal disturbance under open WLAN environment, which introduces decrease in accuracy and stability of the location service. This paper presents a new algorithm, which utilizes multi-space projections of radio space on sub-level signal spaces to mitigate the influence fr...

In this paper, we propose the necessary steps in implementing strong WLAN security for companies using our visual security assessment framework for wireless information assurance. Through real case studies on the organisations with various security measures and by showing complete execution paths of our framework, we suggest the importance of continual assessment of the WLAN for strong corporat...
