Aiming at the security protection and effective search requirements of files in hybrid cloud environment and overcoming the untrustworthiness of third-party cloud services, a secure ciphertext search method for hybrid cloud environment based on file-sensitive data segmentation is proposed.. Using file-sensitive words to split the file into several sub-files. The sub-files is sensitively encrypted and stored in different cloud environments, allowing file to have better flexibility and security, and construct a ciphertext index of segmented ciphertext. Experiments show that this method can complete the secure file search and restoration work in a complex mixed cloud environment.
