Jiyeon Park, Bongjae Kim, Yookun Cho · 2012
The advent of smartphones with a diversity of services using data and inexpensive charge policies has caused an explosion in data usage. The increased data usage introduces new security vulnerabilities in 3G networks, which often experience DoS (Denial of Service) attacks. In this paper, We discuss a type of DoS attack known as a DCH (Dedicated CHannel) starvation attack, which can occur in 3G networks. We then propose a detection scheme using character of the attack.
