“The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks. It is a set of extensions to DNS which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.” (Wikipedia).

This talk will give an overview of the DNS system, some cryptography basics necessary to fully understand the specification and a presentation of the different use cases where DNSSec can be useful.
