The invention relates to a key management method for secure communication. Based on the application, the user communication key container at the client side and the server side can be utilized to replace the storage of the user negotiation communication key in the shadow negotiation communication key state in the server, so that the secure sharing of the user negotiation communication key between different clients of the same user can be realized on the premise of considering the confidentiality of the key; therefore, renegotiation of the communication key negotiated by the user caused by client switching of the same user is avoided. 本申请涉及用于安全通信的密钥管理方法。基于本申请，可以利用客户端侧和服务器侧的用户通信密钥容器，将用户协商通信密钥在服务器中以影子协商通信密钥态替代存储，因而可以在兼顾密钥保密性的前提下，实现用户协商通信密钥在同一用户的不同客户端之间安全共享，以避免同一用户的客户端切换引发的用户协商通信密钥的重新协商。
