In order to help the ICANN community better understand quantum computing and its effects on cryptography, ICANN's Office of the Chief Technical Officer (OCTO) recently published "Quantum Computing and the DNS", This report surveys recent research into quantum computing, and attempts to simplify the complex technical issues enough so that the community can start thinking about the changes it will need to make, and when it will need to make them.
Even though it will probably take many decades to build quantum computers that can affect today's cryptography, the security community is already looking at making changes to TLS within a few years, after new key exchange algorithms are tested and standardized. The DNS community has longer to choose, which is fortunate because signature algorithms that resist quantum computers will have harsher effects on DNSSEC. ICANN will, of course, keep tracking the progress of these new algorithms and will continue to help our community understand their importance.
