4. Authentication/Authorisation Methods • Method for Australian trial is still being developed • Preference of Australian ENUM Discussion Group is to use a mechanism that incorporates digital certificates and an accompanying Public Key Infrastructure • Working group within the Australian ENUM Discussion Group is investigating adapting validation model proposed for Austrian trial (Scalable Architecture for ENUM Number Validation) • Possibly, role of Tier 1 Registry Operator will be extended to included responsibility as Trusted Third Party for authorisation of ENUM subscribers

5. Registration Process • ENUM subscriber registers with registrar. • Registrar authenticates subscriber’s identity and checks that they are authorised to make changes to a particular ENUM domain. • Registrar provisions NAPTR record in Tier 2 Nameserver. • Registrar places entry in the zonefile of the Tier 1 Registry to point at the appropriate Tier 2 Nameserver.

6. Registry/Registrar/Authentication Agency Interface Requirements • Registrar to Tier 1 Registry • All data transfers secure and authenticated • Interface to fully support the Extensible Provisioning Protocol (EPP) on a secure Transport Layer • Each EPP session will be authenticated and encrypted using the Transport Layer Security (TLS) protocol, or a protocol with authentication and encryption capabilities as good or better than TLS • The Tier 1 Registry shall authenticate every EPP client connection using both an X.509 server certificate issued by a trusted Certification Agency nominated by the ACA and its Registrar password

7. NAPTR Formats • NAPTR format Australian ENUM Trial • Minimum requirement for interoperability of European ENUM trials (ETSI TS 102 172)

8. Privacy Aspects • Australian ENUM Discussion Group established separate working group to draft privacy guidelines • Recommendations of privacy working group: • No registrant personal information be exposed to the public via a whois service • A whois service is to be operated for the purposes of technical support but privacy risks to be minimised by: • Allowing nameserver operators to opt-out • Permitting technical contacts to be a role rather than a personal identifier • Only requiring technical contacts to provide one form of contact • Only exposing specific fields to the public

9. Privacy Aspects • Registrant’s personal information collected during the trial is not to be used for secondary purposes (without the registrant’s express consent • Registrant’s personal information is not to be used after the trial without their express consent • Both Registry and Registrar be treated as an “organisation” under the Privacy Act 1998 and comply with National Privacy Principles and other constraints

10. Policy Development • Privacy and security • Rights of Use for ENUM • Charging for ENUM • Competition as we move beyond the trial • Access by agencies like Law Enforcement • Access Emergency services • Equivalent services to people with disabilities
