Abstract:
The present invention relates to the field of data processing, and in particular, to a method for remotely transmitting a key, a receiving terminal, and a distribution terminal. In the present invention, a first authentication message is obtained according to the unique identifier of a receiving terminal and a first random character string; the first authentication message is sent to a distribution terminal, so that the distribution terminal verifies the validity of the receiving terminal according to the first authentication message; a second authentication message from the distribution terminal is verified to obtain a first verification result, the first verification result including verification pass and verification fail, and the second authentication message including the unique identifier of the distribution terminal, a second random string, a second MAC value, and a specific key ciphertext; and when the first verification result is the verification pass, the specific key ciphertext is decrypted to obtain a specific key plaintext.
