MANET has dynamic composition in which nodes are frequently changing, when a node is damaged, reliability between nodes may be changed and they may join in other administrative domains quickly they can rely on. This study suggests security requirements for MANET which can be a base of ubiquitous system and models that can prevent security threat through application of PKI without trusted certificate authority in MANET. It is also solve excessive loading found in centralized control model by dispersing CA for adjustment to dynamic changes of nodes of MANET quickly and suggests a system model which supports expansion so that existing nodes performing communication within clusters can provide active certificate service without being affected by input of new nodes. In addition, it is to evaluate its stability, effectiveness and strength through simulation of the suggested model.
