One-way transmission method based on virtual receiving end

The invention discloses a one-way transmission method based on a virtual receiving end. A client is connected with a virtual receiving end and a one-way receiving end through light splitting equipment; bidirectional connection is established between the client and the virtual receiving end; that is to say, the client initiates TCP connection to the virtual receiving end, one-way connection is established between the client and the one-way receiving end, information transmission from the client to the one-way receiving end is unidirectional, the one-way receiving end does not have any active data communication with the client and the virtual receiving end, and data leakage is prevented. 本发明公开了的一种基于虚拟接收端的单向传输方法，客户端通过分光设备与虚拟接收端和单向接收端连接，客户端与虚拟接收端建立双向连接，即客户端向虚拟接收端发起TCP连接，客户端与单向接收端建立单向连接，客户端到单向接收端的信息传递是单方向的，单向接收端不会对客户端和虚拟接收端有任何主动的数据通信，有利于防止数据的外泄。
