A lot of college wireless networks use software systems and web-based logins to authenticate users. In this paper we find that it is not hard to bypass such authentication. An attacker can use DHCP request to collect information about the users on the network. It makes the attacker much easier to gain unauthorized access to the network facilities. This can be done by putting the network card on monitor...
This study extends the vulnerability analysis of a RFID authentication protocol and offers solutions to security weaknesses through enhanced measures. Vajda and Buttyan (VB) proposed a set of five lightweight RFID authentication protocols. Defend, Fu, and Juels (DFJ) did cryptanalysis on two of them - XOR and SUBSET. DFJ proposed repeated keys and nibble attacks on the XOR protocol. In this paper,...
