Facing with the lack of security in current running client/server systems
this paper designs and implements a kind of secure tunnel gateway system based on SSL/TLS protocol in order to provide seamless security integration to them.Client tunnel gateway and server tunnel gateway authenticate each other based on X.509 certificate
and create SSL/TLS connections to transmit the clients′ requests and servers′ responses.The gateway system uses normal TCP/IP connections to transport data with the clients and servers.It provides confidentiality
integrity and authentication for clients/servers data transmission
which needs no modification to them.Then
this paper presents its test result and application instances.
