This is the third in a multi-part blog series on cryptography and the Domain Name System (DNS). In my last post, I looked at what happens when a DNS query renders a “negative” response – i.e., when a domain name doesn’t exist. I then examined two cryptographic approaches to handling negative responses: NSEC and NSEC3. […]

This is the second in a multi-part blog series on cryptography and the Domain Name System (DNS). In my previous post, I described the first broad scale deployment of cryptography in the DNS, known as the Domain Name System Security Extensions (DNSSEC). I described how a name server can enable a requester to validate the […]
