Classification: CPC H | IPC H

Claim 10:
11. An electronic device, comprising a memory, a processor, and an executable program stored in the memory and capable of being run by the processor, wherein the processor is configured to run the executable program to perform operations of:
handshaking a shared key with a second end through a handshaking message; and
transmitting application data with the second end by a content message, wherein the content message is ciphered and deciphered by using the shared key;
wherein the handshaking message and the content message have a same message format, the message format comprises: a message serial number and a message load;
wherein the message serial number comprises a key algebra identifier and a message count identifier;
wherein the key algebra identifier is represented by bit information having the number of bits less than a first number, and the message count identifier is represented by bit information having the number of bits less than a second number;
wherein the handshaking message comprises at least one of a handshaking greeting message, a handshaking responding message, a retransmission request message, a verification data message, or a handshaking completion message;
wherein the message load of the handshaking greeting message, the handshaking responding message, and the retransmission request message comprises one or more of: a protocol version field, a cipher suite field, a shared key field, or a cipher curve field; and
wherein the message load of the handshaking greeting message or the handshaking responding message comprises a public key list field, the public key list field is a null value, and the null value is configured to determine whether the second end supports a target cipher suite.
