Abstract:

Online social network(OSN)is prone to propagating malware because of their special characteristics.By developing traditional epidemic theory and considering effort intensities of the defender and malware,a differential-equation model to suitably describe characteristics of OSN malware was proposed.Using the differential game,a malware-defense game was constructed to reflect interactions between the defender and malware.Thus,optimal dynamic control strategies for the defender were given when the malware dynamically changed its optimal control strategies.Numerical experiments show that the proposed method is obviously able to suppress the malware propagation.Therefore,a novel way to defend OSN malware was provided.

Key words: online social network, malware, epidemic theory, differential game
