Embodiment Construction
[0019] The invention proposes an authentication encryption method and system based on symmetric encryption and message recoverable signature technology. Specifically include the following steps.
[0020] Step A: The sending end and the receiving end automatically generate public and private keys, and send the public key and their corresponding identities to the server;
[0021] Step B: The sending end receives the public key of the receiving end through the server, the key generation unit of the sending end generates the session key of the sending end according to the public key of the receiving end and the selected random number, and the encryption unit uses the session key of the sending end to pair the message to be sent Encrypt, and use the selected random number, the message to be sent and its own private key to generate authentication information, and the sending unit sends the encrypted message and authentication information to the receiving end through the server;
