Modeling and Performance Analysis of User Behavior Authentication Using Stochastic Petri Nets

Conventional network security control and protective measures based on identity authentication and content authentication can't meet the security requirement of current cloud computing. To address this problem, a behavior authentication mechanism is proposed, which includes establishment of behavior authentication set and behavior authentication strategy. A stochastic Petri net model for this mechanism is constructed. We solve the model by using top-down decomposition and bottom-up hierarchical analysis techniques to decrease the complexity of the model and underling Markov process. This paper further conducts performance evaluation of the system. The research results provide a reference for the design and application of a practical behavior authentication mechanism.
