Data privacy and integrity preserving play important roles in application of the Internet of Things (IoTs). As a part of the IoT, Wireless Sensor Networks (WSNs) should have the function of privacy preserving and integrity checking in data aggregation. This paper proposes a novel Integrity-Preserving Privacy Data Aggregation in sensor networks, which is called IPPDA. Firstly, the "Slicing and assembling" technique is implemented to provide privacy preserving; then aggregation nodes perform delayed aggregation, which trades off a slight increase in communication overhead in return for the ability to execute integrity checking; finally, the child monitoring mechanism is adopted to detect the location of bogus data, remove the compromised node and eliminate communication overhead caused by bogus data.
