Needing the DoH - The Ongoing Encryption and Centralization of DNS

Explore the evolution and implications of DNS encryption in this 40-minute Black Hat conference talk. Delve into the transition from unencrypted DNS requests to encrypted methods like DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH). Examine the motivations behind these changes, including protection against surveillance and data aggregation. Analyze the concerns raised by these new standards, particularly their impact on end users and network operators. Investigate the path to encryption, middleware developments, and the shift towards centralization. Consider the reduced visibility and move to the application layer, as well as supporting platforms. Gain insights into the ongoing debate surrounding DNS encryption and its potential consequences for internet infrastructure and privacy.
