Abstract: Compared to the traditional storage pattern, user can effectively reduce the cost of data storage and management by outsourcing data to cloud storage, and enjoy the advantages of cloud storage such as high scalability and management. Researchers have paid much more attentions on this issue, which is one of the most widely applications and techniques in recent years. Data security has become a recognized issue. Using users’ own private key to encrypt their own data before outsourcing is an effective way to avoid data private leakage, but it will destroy the query capability of data, and bring much more communication cost, storage and computation overhead. The existing searchable symmetric encryption schemes may solve this problem, but it only can be applied to one single data source. Meteorological data is the scarce and valuable resources in meteorology departments, so we should pay much more attentions to the data protection issues.Here, we propose a novel scheme, which may be applied to multiple data sources and has a high-performing. The test results show the our scheme may provide ef ficiently search query result without leaking users’ information and query information.
