Introduction The Lightweight Authenticated Key Exchange (LAKE) protocol [RFC9528] provides points of extensibility, for which related IANA registries exist. When they were created, some of those registries did not include ranges with registration procedure "Private Use" (see Section 4.1 of [RFC8126]). Later on, it was brought to attention that having such ranges available would be convenient for private deployments. This document rectifies this situation by adding Private Use ranges to three IANA registries missing those, as specified in Section 3. 1.1. Terminology This document uses the acronym "LAKE", expanded to "Lightweight Authenticated Key Exchange", to denote the protocol specified as "EDHOC" in [RFC9528]. Identifiers defined literally in [RFC9528] or in IANA registries (e.g., the names of the EDHOC registries themselves) are unchanged.

Security Considerations This document and the Private Use ranges defined in Section 3 do not impact the security of the LAKE protocol. When using values from such Private Use ranges, the security considerations compiled in Section 9 of [RFC9528] still apply. 3. IANA Considerations This document has the following actions for IANA. 3.1. EDHOC Method Types Registry IANA is asked to add the following two ranges to the "EDHOC Method Types" registry [Method.Types] within the "Ephemeral Diffie-Hellman Over COSE (EDHOC)" registry group: * -4294967296 to -65537 * 65536 to 4294967295 For both ranges, the registration procedure is "Private Use" per Section 4.1 of [RFC8126]. 3.2. EDHOC Error Codes Registry IANA is asked to add the following two ranges to the "EDHOC Error Codes" registry [Error.Codes] within the "Ephemeral Diffie-Hellman Over COSE (EDHOC)" registry group. * -4294967296 to -65537 * 65536 to 4294967295 For both ranges, the registration procedure is "Private Use" per Section 4.1 of [RFC8126]. 3.3. EDHOC External Authorization Data Registry IANA is asked to add the following range to the "EDHOC External Authorization Data" registry [External.Authorization.Data] within the "Ephemeral Diffie-Hellman Over COSE (EDHOC)" registry group: * 65536 to 4294967295 For this range, the registration procedure is "Private Use" per Section 4.1 of [RFC8126].

Acknowledgments Tobias Müller pointed out the usefulness of a Private Use range for External Authorization Data (EAD) labels, which triggered the development of this document.
