JG - "An Allocation Token should be considered secret information by the client and should be protected at rest and in transit." can be changed to "An Allocation Token should be considered secret information by the client and SHOULD be protected at rest and MUST be protected in transit." ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- S 3.2.4. > like [RFC5731], the command MUST contain a child > <allocationToken:allocationToken> element for the client to be > authorized to transfer and allocate the object.

If the Allocation Token is invalid or I'm having trouble processing this statement. Can you explain in more detail what the two access control checks are here. JG - RFC 5731 includes support for an authorization info (<domain:authInfo>) that is an existing credential stored in the server at the time of the create command, which can be updated with an update command, that is used by the gaining client (registrar) to authorize a transfer request. The registrant should have access to the authorization info from their sponsoring registrar to pass to the gaining registrar to authorize the transfer request. The Allocation Token is not meant to replace the RFC 5731 authorization info, but is meant as an additional credential to authorize the "allocation" of the domain name. A registry may hold premium domain names that have an authorization info value, and leverage the transfer command for use in allocation with the use of the additional allocation token. Let me know if you need any additional clarification on this.

The following are security > considerations in the definition and use of an Allocation Token: Do you want to use normative language here? JG - Are you requesting normative language such as "The definition of the Allocation Token SHOULD be defined outside of this mapping". There are cases when the allocation token is a non-complex string value that does not require formal definition, so the normative SHOULD seems most appropriate here. Do you agree? S 7. > 3.

JG - An unsigned code is a non-complex string that the server generates and stores with the domain name, which can be later validated during allocation. _______________________________________________ regext mailing list regext@ietf.org https://www.ietf.org/mailman/listinfo/regext
