>"b. Data plane anonymization allows entities to communicate anonymously from the outside observers. Identity provides deanonymization for various data plane ephemeral Identifiers, >if required, and enables resolution of which entity is behind these identifiers for legitimate users (entities itself in some cases)." >Data plane anonymization exists by virtue of providing a hosts multiple addresses or identifiers and not putting anything in a packets that allow cross correlation. Identity is not required to achieve anonymization. >Per the text, identity provides for deanonymization which seems to contradict the goal of anonymization. The text also states that deanonymization would be done "if required". >So my question is under what circumstances would deanonymization be required? [Uma]: Great question. It's possible, in case if receiving entity of the data traffic want's to control which entities it wants to receive the traffic from (or prioritize them). A simple example could be a connected vehicular node/IoT may want to receive traffic from only certain entities (dealer or manufacturer or xyz) updates and their long-lived ID's are used in the local policy at the receiving end. If one of the legit sending entity uses anonymized identifier; receiving entity might want to de-anonymize the same before accepting the traffic - to see if it matches to the corresponding long-lived Identifier it set the policy for. This is one example for the description of section 2, point B you quoted. Best Regards, -- Uma C.
