In mobile ad hoc networks (MANETs), a single certificate authority (CA) node could be a security bottleneck. Multiple replica of CA is fault tolerant, but the network is as vulnerable as single CA or even worse since breaking one of the CAs means breaking all of them. Many distributed CA models based on the secret sharing scheme are proposed. In this paper, the efficiency and usability of the distributed CA are analyzed based on the queuing theory. By the analyzing of the characters of the distributed CA in MANETS and the processes of the secure services provided, the queuing model is built. We conduct an investigation into some performance measures of the model and especially focus on the mean response time and the loss probability of the secure service applications. The conclusions are instructive for the design of distributed CA applied in MANETs.
