A reputation bootstrapping approach for computer network collaborative defense

Computer network collaborative defense is used to protect networks from collaborative attacks. To ensure the credible of defense entities, trust relationships are necessary to be established. When there are not enough history records for reputation evaluation, the reputation bootstrapping technique to establish an initial reputation value for newcomers based on limited record about their past behaviors becomes important and is short of a proper solution currently. We present a reputation bootstrapping approach. Our approach considers about different node types and gives each node a reputation different from each other, reflecting the specific status of the new nodes. Experimental results show that the approach minimizes the future failure rate of coordination.
