Safety browser realizing method and safety browser device

The invention provides a safety browser realizing method and a safety browser device. The method comprises the steps that an encryption subprocess communicating with a browser main service process is started in a browser client side, wherein the encryption subprocess is used for serving as a connecting agent to achieve converting and data forwarding from a first encryption channel to a second encryption channel; the encryption subprocess monitors the browser main service process and obtains a first connecting request transmitted by the browser main service process; according to the first connecting request, encryption connection and communication are set up between the encryption subprocess and a network server; after the encryption connection and communication are set up successfully, the encryption subprocess executes service data forwarding between the first encryption channel and the second encryption channel; the first encryption channel is a safety communication channel between the browser main service process and the encryption subprocess; the second encryption channel is a safety communication channel between the encryption subprocess and the network server.
