Welcome to NOPE

NOPE is a research project focused on improving server authentication by reducing dependence on certification authorities (CAs).

Instead of solely relying on CAs, NOPE introduces a new method that uses succinct proofs, such as zero-knowledge proofs, to demonstrate the existence of a DNSSEC chain linking a public key to a domain.

This approach is compatible with existing TLS servers and certificate formats, adding minimal overhead and preserving Internet security against compromised CAs.
