Transmission Control in Transport Protocols for Mitigating Effects of Pulsing Denial of Service Attacks
Hiroshi Tsunoda, Kenjiro Arai, Yuji Waizumi, Yoshiaki Nemoto (Tohoku Univ.) CS2007-8
Abstract (in Japanese) (See Japanese page) 
(in English) Pulsing Denial-of-Service (DoS) attacks, which can significantly
degrade the communication quality (e.g. throughput) of legitimate TCP
flows in a stealthy manner, are new serious threat in the Internet. Pulsing DoS attacks The attacker send periodic short bursts of traffic (i.e. pulses) to cause packet losses of TCP flows. To mitigate the effect of this attacks, randomizing retransmission timeout value of TCP is useful. However, such randomizing can degrade the communication quality in the normal situation.
In this paper, we propse to change the retransmission timeout value
only when the attacks are detected at an intermediate routers.
In the proposed method, intermediate routers notice the existence of
attacks in a manner similar to Explicit Congestion Notification (ECN).
In addition, we also discuss the effect of the attack on SCTP.
