讲座摘要:
The use of a multitude of compromised and globally distributed devices and Internet connections makes Distributed denial of service (DDoS) attack one of the most difficult cyber threats to defend against. Different from the traditional ways with the focus on detecting and stopping malicious users and requests, we propose a virtual economic model which aims at effectively preventing malicious traffic by employing micro-payments to each coming request. The entire targeted network imitates an economic society where a credit system is established based on the micro-payment records of all devices and network connections. Along with the credit system, the utility theory is applied in determining the micro-payment of each coming request. The long-run equilibrium in such virtual economic network states legitimate clients are free of charge. By additional experiments, we illustrate the efficiency of such economic model in blocking bad requests.
