Research on Trusted Network Model Based on BLP Model

With the growth of network in size and complexity, the isolated security systems are facing many challenges and they can not meet users´ needs. As a new type of network, trusted network can make up for security defects of traditional network, change from passive recovery to active attack and end vicious network behaviors from head. Researching trusted network model is popular nowadays. Based on BLP model, considering securities of network, a trusted network model is proposed in this paper. Related definitions of this model are given and security properties of this model are defined. Security policies and rules of restricting and analyzing behaviors are presented.
