With the development of the internet of things,more and more encrypted data information stored on the cloud server.When the server stored encrypted data for a certain scale,the encrypted data retrieval become a urgent problem to be solved.The paper presents an information retrieval scheme based on Paillier homomorphic encryption algorithm,which is used in the Internet of things.This algorithm can not only directly retrieve the encrypted data and ensure the retrieval of data not to be statistical analysis,but also can be retrieved the data in basic additive operation without changing the order of the plaintext The data security of users is protected and the retrieval efficiency is improved.
