CS Faculty Member Awarded "Annual Applied Networking Research Prize"!
Taejoong Chung has been awarded the IETF/IRTF Annual "Applied Networking Research Prize"
for his paper titled "Understanding the Role of Registrars in DNSSEC Deployment".

The Domain Name System (DNS) provides a scalable, flexible name resolution service. Unfortunately,
its unauthenticated architecture has become the basis for many security attacks. To address this,
DNS Security Extensions (DNSSEC) were introduced in 1997. DNSSEC’s deployment requires support from
the top-level domain (TLD) registries and registrars, as well as participation by the organization
that serves as the DNS operator. Unfortunately, DNSSEC has seen poor deployment thus far: despite
being proposed nearly two decades ago, only 1% of .com, .net, and .org domains are properly signed.
In this paper, we investigate the underlying reasons why DNSSEC adoption has been remarkably slow.
We focus on registrars, as most TLD registries already support DNSSEC and registrars often serve as
DNS operators for their customers. Our study uses large-scale, longitudinal DNS measurements to study
DNSSEC adoption, coupled with experiences collected by trying to deploy DNSSEC on domains we purchased
from leading domain name registrars and resellers. Overall, we find that a select few registrars are
responsible for the (small) DNSSEC deployment today, and that many leading registrars do not support
DNSSEC at all, or require customers to take cumbersome steps to deploy DNSSEC. Further frustrating
deployment, many of the mechanisms for conveying DNSSEC information to registrars are error-prone
or present security vulnerabilities. Finally, we find that using DNSSEC with third-party DNS operators
such as Cloudflare requires the domain owner to take a number of steps that 40% of domain owners do
not complete. Having identified several operational challenges for full DNSSEC deployment, we make
recommendations to improve adoption.
About the award:
The Applied Networking Research Prize (ANRP) is awarded for recent results in applied
networking research that are relevant for transitioning into shipping Internet products
and related standardization efforts.
The goal of the Applied Networking Research Prize is to recognize the best new ideas in networking,
and bring them to the IETF and IRTF especially in cases where they would not otherwise see much exposure
