Soca: A Source-Oriented Cooperative Approach For Mitigating Dos/Ddos Attack In Identifier Locator Separation Mapping Based Mobile Internet

With the growing popularity of mobile Internet, attacks from mobile users have increased tremendously, causing difficulties in providing reliable and ubiquitous services for end users. Mobile users can attack network elements by sending malicious packets towards the same or different destinations. Based on identifier locator separation mapping based mobile Internet and Reputation Level (RL)-based access scheme studied in our previous work, we propose a source-oriented cooperative approach (SoCA) for mitigating DoS/ DDoS attack in identifier locator separation mapping Internet with GPRS access. In particular, SoCA can trace the potential source by using IMSI, and works cooperatively with the network unit in GPRS access networks. SoCA is analyzed theoretically by proposing an analytical model for traffic acceptance probability, which is related to user and service visit behavior. Numerical results show that the attack can be effectively eliminated by adapting the traffic acceptance probability to the users and service visit behavior.
