The invention provides an abnormal data resisting and privacy protecting data aggregation system and method. The abnormal data resisting and privacy protecting data aggregation system comprises a system model and a security model. In the system model, an intelligent electric meter SM is mainly responsible for measuring real-time power consumption data of a user and safely reporting the real-time power consumption data to an aggregation center AC; the aggregation center AC collects the electricity utilization information uploaded by each intelligent electric meter and aggregates the electricity utilization information; after the aggregation process is finished, the aggregation center AC sends an aggregation result and the false identity information of the abnormal ammeter to a cloud server; and the cloud server CS is responsible for decrypting the encrypted aggregation result so as to obtain a real aggregation result, so that reasonable production decision and power distribution can be carried out. The method
