1. 11. A Comprehensive Taxonomy of Attacks and Mitigations in IoT Wi-Fi Networks : physical and data-link layer

   M1-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Författare :Sarmed Almjamai; [2022]
   Nyckelord :Attack; Mitigation; Tools; Vulnerability; Security protocol; WPA2; WPA3; Wi-Fi; IoT; physical layer; data-link layer; MitM; DoS; Key-recovery; Traffic decryption;

   Sammanfattning : The number of Internet of Things (IoT) devices is rising and Wireless Fidelity (Wi-Fi) networks are still widely used in IoT networks. Security protocols such as Wi-Fi Protected Access 2 (WPA2) are still in use in most Wi-Fi networks, but Wi-Fi Protected Access 3 (WPA3) is making its way as the new security standard. LÄS MER

3. 12. Puzzle-based Clogging DoS-resilient Vehicular Communications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
