  15. What about IEEE?

  16. Draft IEEE Standards • IEEE 1609.1: WAVE Resource Manager • Defines “Basic Application Platform” • Application data read/write protocol between RSU and OBU • First application available for testing purposes • IEEE 1609.2: 5.9 GHz Intelligent Transportation System (ITS) Radio Service Security • Defines 5.9 GHz DSRC Security (formerly IEEE 1556) • Anonymity, Authenticity and Confidentiality • IEEE 1609.3: WAVE Networking Services • Provides description and management of the DSRC Protocol Stack • Application interfaces • Network configuration management • WAVE Short Message (WSM) transmission and reception Q-Free ASA

  17. Draft IEEE Standards (cont’d) • IEEE 1609.4: WAVE Multi-Channel Operation • Provides DSRC frequency band coordination and management • Manages Lower Layer usage of the seven DSRC channels • Integrates tightly with IEEE 802.11p • IEEE 802.11p: Wireless LAN Medium Access Control (MAC) and physical layer (PHY) specifications: Wireless Access in Vehicular Environments (WAVE) • Defines the Lower Layers of the communications stack • Radio wave forms and wireless medium access procedures Q-Free ASA

  18. IEEE Standards Status • Latest IEEE 1609 draft documents completed in December 2005 • IEEE 1609 status: • 1609.1 completed sponsor ballot, 500+ comments • 1609 part 2-4 launched mid-January for 30 days sponsor ballot. Many comments are expected • Project approval all parts expected June 2006. • IEEE 802.11p is also progressing • Latest pre-Hawaii draft is D0.25 • Possible ballot in March 2006? (IEEE 802.11) Q-Free ASA

  19. IEEE Security Services • 5.9 GHz DSRC uses Public Key Infrastructure (PKI) to sign and/or encrypt DSRC data • Anonymity (prevents tracking - Privacy) • MAC address randomization • Security certificates may also be periodically changed • Opt-in services may not require anonymity • Authenticity • Digital signatures protect against various malicious security threats • Confidentiality • Data may also be encrypted to provide data privacy • Safety messages broadcast from RSUs do not always require encryption (digital signatures are always required) Q-Free ASA

  20. CALM and Security • CALM relates to security as follows: • Interface specific for lower layers or low latency • Application or protocol specific for higher layers (ETC, IPSEC,…) • There are no specific security means built into CALM • Vehicle Probe Data (ISO 24100) has provisions for protection of privacy. • CALM is interested in input from SeVeCOM.Liaison?
