摘要：In this paper, we consider the security problem of public opinions when it has terrorists who try to guide people's opinions to malicious ones in social network. First, we propose an opinion dynamics model, which is composed by the suspects, the defenders and the masses. In this model, a set of suspects influenced by the terrorists at the beginning send malicious opinions to their neighbors. Similarly, the defenders spread the government's opinion to resist people's opinions following that of terrorists. Second, we consider the random communication among neighbours, where people can not interact with each other every time. At the last, we provide a sufficient condition to ensure the convergence of the expected opinions of the system. Finally, we provide some numerical examples to illustrate all the derived results. ? 2018 IEEE.
