To prevent network infrastructure from malicious traffic, such as DDoS attack and scanning, source filtering is widely used in the network. There are different ways to store the filters, e.g., a blacklist of source addresses. Among them, TCAM-based is used as the de facto, because of its wire speed performance. Unfortunately, TCAM is a scarce resource because it's limited by small capacity, high power consumption and high cost. There are chances like a data distributor had given his sensitive data to a set of trusted agents. These agents can be called as third parties.
