The invention discloses a reliable
road condition message transmission method based on vehicle-mounted
fog computing. The method comprises a registration stage, a
mutual authentication and key negotiation stage, a
road condition monitoring stage and a partial private key updating stage. According to the method, an
authentication mechanism of the vehicle and the
fog node for ensuring
secure communication between the vehicle and the FN is provided without real-time participation of a
trusted authority TA, the defects of long message
transmission time and low message
authentication and integrity in a traditional
anonymous authentication protocol are overcome, the
system efficiency is improved, and the communication overhead is reduced. A lightweight vehicle privacy security protection
authentication scheme based on
fog computing is provided to protect the vehicle privacy and minimize the vehicle storage burden. Under the condition that the real identity of the vehicle is not leaked, the identity information generation mode and the
session key of the V2F are redesigned, the problems that identity authentication between the V2Fs is complex, the identity
information storage amount is large, and communication messages are prone to
attack are solved, the communication safety is improved, and the vehicle storage burden is relieved.
