Privacy-preserving authentication and key management for cooperative intelligent transportation systems

Car accidents kill or injure millions of people. Cooperative Intelligent Transportation Systems (C-ITS) can increase road safety and reduce accidents through the application of information and communication technologies for communicating vehicles. However, C-ITS applications are vulnerable to potential cyber-attacks involving message manipulation, where messages may be altered intentionally or fake messages sent, compromising the safety goals. Cryptographic techniques can be used to solve this, but this must be done in a way that preserves driver privacy, so that unauthorized surveillance and tracking of drivers is not possible. This research develops a secure conditional privacy-preserving authentication scheme for C-ITS applications
