DNSSEC With Multiple Providers

About this talk

DNSSEC is a system to verify the authenticity of data in the DNS, and allows us to detect DNS spoofing and cache poisoning. Many organizations today leverage multiple distinct DNS providers to serve their DNS zones, for increased redundancy and survivability. Deploying DNSSEC in such an environment presents challenges when each provider signs zone data with their own keys. In this talk, we will give an overview of DNSSEC, and describe joint work we have done with NS1 to develop a system to successfully enable "Multi-Signer" DNSSEC deployments.
