The REGRR protocol Daniel Kalchev, Register.BG ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
Protocol design • Signed XML messages over encrypted communication channel • No need to keeping session or state at the server • Each message carries full authentication and authorization properties by virtue of digital signatures • Regular command:object structure • Nested message structure • Nomenclature versions are communicated with each message • The various nomenclature lists can be communicated between server and client ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
What REGRR achieves • Secure communication with Registrars • Secure communication with Registrants • End to end encryption and signing • Separate authorization of the Registrant and Registrar to modify Registry data • Follows contractual relationships • Solves the issues of Registrars having too much control over Registrant data ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
How it works • The Registrant prepares and signs the message, possibly via the Registrar interface (could be web based or other protocol) • The Registrar signs the Registrant message and communicates it to the Registry • The Registry authenticates sources based on digital certificates and authorizes object modification based on object ownership and assigned rights • The Registrant could authorize the Registrar to submit messages on their behalf • The Registrant can communicate messages directly with the Registry, providing for secure updates for DNS and DNSSEC data. ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
Current implementations • Implemented and published 2011 by Register.BG • Three of .BG’s Registrars at various implementation levels • Current server implementation runs on TLS/TCP • Specification/documentation being translated to English… ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
Thank You Daniel Kalchev, Register.BG daniel@digsys.bg ICANN48, Buenos Aires 16-21 Nov 2013 Register.BG REGRR Protocol
