The problem with secure connection between devices in local network is that such a self-signed certificate is not trustworthy, because the certificate cannot be validated with root CA's certificate.

To solve this problem, we need to find another mechanism to validate whether the local server would be trustworthy or not without relying on root-CA-based PKI (e.g. J-PAKE, as we have discussed so far). I guess that such a trust model looks like overall problem with securing connections on open screen protocol, not limited to HbbTV or ATSC.

Anyway, some sort of addition or modification to TLS authentication mechanism or certificate management would be necessary for HbbTV and ATSC (and possibly Hybridcast in Japan), unless the user would be asked to install private CA to validate local server's certificate on their browser or OS.

Note that Hybridcast is facing the same problem, and eventually they are now using native apps instead of web browsers as a companion screen for Hybridcast.
