Method of performing integrity verification between client and server and encryption security protocol-based communication method of supporting integrity verification between client and server

An encryption security protocol-based communication method of supporting integrity verification between a client and a server, the encryption security protocol-based communication method comprising:

• receiving, by the server, a first message from the client, the first message comprising a request for a first integrity verification of the client so as to start a handshake of a transport layer security (TLS) connection;
• transmitting, by the server, a second message to the client, the second message comprising a request for first verification information for the first integrity verification;
• receiving, by the server, the first verification information from the client, and performing the first integrity verification by using the first verification information;
• and
• finishing the handshake and performing data communication between the client and the server based on a result of the first integrity verification.
