Description
of Security Approach
§Three key elements:
1.Public Key Infrastructure (PKI)
2.Vehicle and other security
elements
3.Policies
1.PKI is an umbrella term used to describe the hardware, software,
people, policies, and procedures needed
to create, manage, store, distribute, and revoke digital certificates. For V2V/V2I, the PKI establishes trusted messages:
▪Provides authorization credentials to
vehicles for participation in the network
▪Facilitates the revocation of
credentials if an administrating authority decides to do so.
2.Vehicle and other security elements at
the local (vehicle) level are incorporated to prevent
misbehavior and detect misbehavior already occurring within the system. These
include:
▪Hardware: standard controller on the vehicle +
tamper-proof encasements
▪Software: functionality checks and misbehavior
detection processes
