Abstract: An information processing method, a terminal device, and a network system include encrypting, by a first terminal, an authorization key based on a public key of a second terminal to obtain an authorization key ciphertext corresponding to the second terminal, and sending, by the first terminal, the authorization key ciphertext to the second terminal such that the second terminal decrypts the authorization key ciphertext based on a private key of the second terminal to obtain the authorization key, and then performs file decryption.
