IEEE 1609.2B:2019

Scope
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).
Purpose
The safety-critical nature of many Wireless Access in Vehicular Environments (WAVE) applications makes it vital that services be specified that can be used to protect messages from attacks such as eavesdropping, spoofing, alteration, and replay. Additionally, the fact that the wireless technology will be deployed in communication devices in personal vehicles as well as other portable devices, whose owners have an expectation of privacy, means that in as much as possible the security services must be designed to respect privacy and not leak personal, identifying, or linkable information to unauthorized parties. This standard describes security services for WAVE management messages and application messages designed to meet these goals.
Abstract
Amendment Standard - Active. Secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages are defined. Administrative functions necessary to support the core security functions are also defined.
