| description | Disclosed in the present application are an encrypted file retrieval method and system, a terminal device and a storage medium, the encrypted file retrieval method comprising: a first terminal uses a first user secret key for encrypting a shared file and sends index information corresponding to the encrypted file and the shared file to a server; the server uses a first server secret key to encrypt the encrypted file; a second terminal sends target keyword information to the server; the sever obtains a target double encrypted file which matches retrieved target keyword information according to the target keyword information and uses a second server secret key to decrypt the target double encrypted file; the server sends the target encrypted file to the second terminal; and the second terminal uses a second user secret key for decrypting the target encrypted file. According to the technical solution of the present application, multiple authorized users may retrieve a shared file by means of respective different |
