  1. ENUM validation architecture & friends Bernie Höneisen SWITCH / 1.4.e164.arpa hoeneisen@switch.ch Alex Mayrhofer enum.at / 3.4.e164.arpa alexander.mayrhofer@enum.at draft-mayrhofer-enum-validation-arch-00 draft-hoeneisen-enum-validation-epp-01 draft-lendl-enum-validation-token-00 IETF63 - enum WG

  2. Motivation & Goals Motivation: • Solving validation is crucial for ENUM deployment • Major reason why trials precede production • Validation is the major difference between ENUM and "ordinary" domain registration • Validation definition and requirements currently vague • Common view considered useful Major Goals: • Common understanding • Terminology, Processes, Roles, … • Keeping entropy low • Minimize number of solutions addressing same problem • Prevent reinventing the wheel – foster deployment instead IETF63 - enum WG

  3. validation draft orientation map Role model Process & trust assumptions validation data transport validation data format Requirements draft-mayrhofer-enum-validation-arch draft-hoeneisen-enum- validation-epp EPP draft-lendl-enum-validation-token SOAP? XML E.115 IRIS? alternative formats? Other? IETF63 - enum WG

  4. Disclaimer • It is out of scope of these documents how an actual validation is performed ("validation method") • The documents just attempt to provide a generic framework to base validation processes and communication on. IETF63 - enum WG

  5. draft-mayrhofer-enum-validation-arch-00 ENUM Provisioning Model & Roles Legend VE: Validation Entity NAE: Number Assignment Entity ENUM Registry trust relation registration VE ENUM Registrar validation E.164 number assignment verification ENUM management Registrant / Assignee NAE number assignment IETF63 - enum WG

  6. draft-mayrhofer-enum-validation-arch-00 Validation Requirements • The ENUM domain name corresponds to an assigned E.164 number • The corresponding E.164 number is within a number area approved to be used with ENUM • The registration of the ENUM domain name isauthorized by the Assignee of the corresponding E.164 number • The Registrant of the ENUM domain name is identical to the Assignee of the corresponding E.164 number IETF63 - enum WG

  7. Initial vs. recurring validation • Initial Validation • Verify requirements before registration of the ENUM Domain takes place • Recurring Validation (Re-Validation) • Verify that requirements are still satisfied • usually making use of data acquired during initial validation • domain is to be removed when corresponding E.164 number is e.g. revoked IETF63 - enum WG

  8. draft-mayrhofer-enum-validation-arch-00 Registration process assumption Legend VE: Validation Entity NAE: Number Assignment Entity ENUM Registry trust relation 5 registration VE ENUM Registrar validation 3 ENUM management 2 E.164 number assignment verification 4 1 Registrant / Assignee NAE number assignment IETF63 - enum WG

  9. existing RFCs policy dependent common (policy independent) example validation token enum.at some other suitable XML transport mechanism (e.g. SOAP) other variant? Draft-hoeneisen-enum-validation-epp-01 / draft-lendl-enum-validation-token-00 Transport / data format extension framework EPP domain EPP validation framework EPP draft-hoeneisen-enum-validation-epp-01 Scott's EPP RFCs draft-lendl-enum-validation-token-00 IETF63 - enum WG

  10. draft-hoeneisen-enum-validation-epp-01 EPP transport • Framework for Transport of validation information along with the EPP Domain object • Elements for validation information itself are out-of-scope of this document • Example for better readability included • enables usage of different locally adjusted validation information elements or "tokens" IETF63 - enum WG

  11. draft-lendl-enum-validation-token-00 Validation Token • Conveys information about a validation • E.164 Number (obviously) • Contact information (in the style of EPP and E.115) • Serial, validation method, validator, expiration … • XML schema • Optional cryptographic signature • Non-repudiation • Authenticity • Supports trust relation between VE and registry • To be embedded in transport protocols • EPP (Bernie's draft, enum.at implementation) • SOAP? Email? HTTPS? • In productive use for 3.4.e164.arpa. • Probably useful for other purposes (number porting?) IETF63 - enum WG

  12. Next steps • How to proceed withdraft-mayrhofer-enum-validation-arch ? • WG item? • Feedback requested on documents – in particular from folks working on ENUM provisioning implementations IETF63 - enum WG
