An Analysis of the Impact of the AuthRF and AssRF Attacks on IEEE 802.11e Standard

The paper shows detailed analysis of the effects of the AuthRF (Authentication Request Flooding) and AssRF (Association Request Flooding) MAC Layer DoS (Denial of Service) attacks on 802.11e wireless standard based on a proposed queuing model. More specific, the paper analyzes the Access Point (AP) behavior under AuthRF DoS attacks with different frequency of the requests arrival, i.e. Low Level (LL), Medium Level (ML) and High Level (HL), at the same time considering different traffic priorities. The proposed queuing model and the developed analytical approach can be also used on each protocol layer, especially if the attacks are seen in terms of the flooding influence over AP with too many requests (ICMP, TCP SYN, UDP etc.).
