TLS secure communication method and system

The invention discloses a TLS secure communication method. The method comprises the following steps: a server and a client call certificates of each other; encrypting an encryption suite and key exchange information sent by the client by adopting the public key of the server certificates; encrypting the encryption suite selection and key exchange information sent by the server by adopting the public keys of the client certificates; allowing the client to decrypt the received encryption suite selection and key exchange information sent by the server by using the private key of the client; and allowing the server to decrypt the received encryption suite selection and key exchange information sent by the client by using the private key of the server. The TLS secure communication method has the beneficial effects that the secure communication method is suitable for occasions with relatively high data transmission security requirements; synchronous updating of certificates of the two parties can also be included i
