The invention discloses a secure communication method of a secure server. The secure communication method of the secure server comprises the following steps of (1) registering information through an information verification terminal, and binding a user ID and a business system operation terminal internet protocol (IP); (2) checking biological characteristics of a user; (3) registering through the business system operation terminal IP which is bound with the user, and checking the state of the user in the information verification terminal through a proxy server; (4) the business system operation terminal IP accessing the secure server through the proxy server; (5) logging off verification information of the user. The invention further discloses a system which is used for implementing of the communication method, and the system comprises the proxy server, a business system operation terminal, the information verification terminal and the secure server. The business system operation terminal, the information verification terminal and the secure server are respectively connected with the proxy server in a communication mode. The proxy server conducts data forwarding between the business system operation terminal and the secure server, so that the secure server is invisible in the business system operation terminal and illegal operation of the secure server is avoided.
