IEEE 1609.2 and Connected Vehicle Security: http://csrc.nist.gov/groups/ST/ssr2016/documents/presentation-tue-whyte-invited.pdf

• The Connected Vehicle system is going to result in more than 300 million devices with needs for secure communication.
• In 2003, the decision was taken to create a standard for security for this communication that was distinct from existing standards 
  • X.509, S/MIME-CMS, etc 
• The standard, IEEE 1609.2, contains a number of crypto and protocol design decisions that are different from protocols attempting to do similar things 
  • Although it was developed in public, and although it will go into cars, it has not received the level of scrutiny that higher profile standards have 
• In 2012, the US and European versions of this standard diverged and are now incompatible 
  • Creates a dilemma for, e.g., Australia
