Support for Elliptic Curve Cryptography (ECC) in DNS Resolvers as Seen by RIPE Atlas

Maciej Andzinski

6 min read

The Elliptic Curve Cryptography (ECC) is becoming increasingly popular in DNSSEC. While it is sometimes considered to be a remedy for the low DNSSEC adoption rate, there is also a lot of controversy around it. One of the main concerns is that DNSSEC-validating resolvers don't always make use of ECC…
