the client and the server agree to use the TLS protocol, they negotiate a stateful connection to transfer the data by using a handshake process. By shaking hands, the client and server negotiate various parameters for creating a secure connection:When a client connects to a server that supports the TLS protocol, it requires the creation of a secure connection and lists the supported password combination handshake to start.The server determines the encryption and hashing functions from this list

OpenSSL provides a powerful feature in this area, and is open source, now widely used in the network communication mechanism;3. By deploying a CA (Certificate authority) server within a certain scope, the certificate authentication and authorization can be realized in the LAN, and the security of data transmission can be ensured, and the working principle of the international large CA institution may be un

CA has conditional receiving system and scrambling and encrypting two parts. Scrambling is an image, sound, and data stream under the control of a CW (or a key) in a way that makes it impossible to watch, and encryption is the process of protecting the key. The encrypted key must be transmitted to the client along with the scrambling signal. On the client side, the solution CW is decrypted with the smart card, and the scrambling signal is disturbed by
