Short paper: Tri-party TLS Adaptation for Trust Delegation in Home Networks

Home networking has come in wider use, thus appealing to an increasing need for security. Emerging social concepts such as telecommutation brought a new kind of security threats to the home environment. Besides, low-capacity devices in the home domain may need a central entity dedicated to security enforcement. As SSL-based VPN solutions don’t provide end-to-end tunnels, we have extended TLS protocol to delegate trust establishment between a home network server and an external client to a security gateway, acting as a reverse proxy. Moreover, we formally validated it using automatic protocol analyzer AVISPA.
