Users of public Wi-Fi networks risk being tricked into connecting to `evil twin' access points set up by attackers to launch man-in-the-middle attacks. We present a system which employs post hoc validation of an anonymous Diffie-Hellman key exchange undertaken as part of an 802.1X/EAP-TTLS network association process. Our system utilises an additional secure auxilliary channel to run a modified version...
A Bluetooth ad hoc network can be formed by interconnecting piconets. The security of the process of Bluetooth scatternet formation is a major factor to guarantee the applications of Bluetooth network. Through the analysis of the characteristics of Bluetooth scatternet formation algorithm and Bluetooth's security architecture, this paper gives out a scheme for Bluetooth scatternet security based on...
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but its security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against...
