Summary:
DNS-over-TLS was introduced to improve user privacy, as DNS packets are currently sent over the Internet in plaintext. However, DNS-over-TLS still suffers from privacy issues from malicious recursive resolvers and also usability issues. PDoT is a novel recursive resolver architecture that aims to overcome both of these issues using Trusted Execution Environments (TEEs).

Summary:
Named Data Networking (NDN) is one of the emerging future Internet architecture that aims to put content in the center of the communication. Similar to the current Internet, NDN also suffers from DDoS attacks. FROG aims to detect and mitigate DDoS attacks in NDN using a novel method that utilizes packet hop counts.
