IEEE 1609.2b-2019

This amendment extends the secure communications functionality of Std 1609.2-2016 and Std 1609.2a to provide one additional field in the signed data structure to support Secure Protocol Data Units (SPDUs) received by a functional entity other than an application. Additionally, this project clarifies the use of the encryption primitives within 1609.2-2016, explicitly allowing an ephemeral data encryption key to be exported from the encryption primitive for later reuse. Finally, this project expands some elements of the Protocol Implementation Conformance Statement (PICS) proforma to provide better coverage of the approach to peer-to-peer certificate distribution favored by the European Telecommunications Standards Institute (ETSI).
