This invention discloses a time-constrained, secure, and controllable data flow method in a cloud-edge environment, belonging to the field of mobile edge cloud computing. Specifically, it involves: First, establishing a communication scenario including an authorizing agency for both the sender and receiver, the sender, edge nodes, a cloud server, and the receiver. Given security parameters, the authorized agency for the receiver runs a global initialization algorithm, outputting public parameters and domain public / private keys. Then, the authorized agency for the sender inputs the public parameters and domain public key, outputting its own domain public / private key. For each sender, an access structure and a valid time interval are assigned, and an encryption key is generated. For each receiver, an attribute set is assigned, and a decryption key is generated. Finally, the sender runs the encryption algorithm and outputs the original ciphertext; the edge node verifies the sender's sending authority and outputs the cleaned ciphertext; and the legitimate receiver decrypts and outputs the plaintext. This invention meets the requirements for secure and controllable data flow in a cloud-edge environment.
