Karl Koscher - Enabling HTTPS for home network devices - DEF CON 27 Crypto and Privacy Village
Channel: DEFCONConference
Date: 2019-11-27

Let's Encrypt has enabled rapid adoption of TLS across the long-tail of public-facing services. Unfortunately, there are still challenges in deploying TLS on home network devices, such as routers, TV tuners, and IoT hubs. These devices are commonly accessed by their non-routable, dynamically-assigned IP address, preventing traditional domain-validated certificates from being used. This talk introduces a new DNS-based service that allows home network devices to automatically request certificates that can be used with non-routable IP addresses.
