Connection establishment method and system, terminal and computer readable storage medium

The invention discloses a connection establishment method and system, a terminal and a computer readable storage medium. The connection establishment method comprises the following steps: in a discovery process of terminal-to-terminal relay communication, a first terminal sends a discovery message carrying an indication to a second terminal, and the indication is used for determining whether to use a network-assisted secure connection establishment process between the first terminal and the second terminal. According to the embodiment of the invention, the selection of whether to carry out network-assisted secure connection is provided for the terminal-to-terminal relay communication, the participation degree and the control force of the network side in the terminal-to-terminal relay communication process are increased, the service security is improved, and the user experience is enhanced. 本发明公开了一种连接建立方法、系统、终端和计算机可读存储介质。连接建立方法包括：在终端到终端中继通信的发现过程中，第一终端向第二终端发送携带指示的发现消息，指示用于确定是否在第一终端和第二终端之间使用网络辅助的安全连接建立过程。本发明的实施例
