Abstract:
The automotive industry has undergone a remarkable evolution over the
past few decades, characterized by numerous technological advancements
and emerging trends like electrification and autonomous driving,
which reshape the future of vehicles. As automobiles become increasingly
connected and reliant on complex software systems, the need to
safeguard them from potential cyber threats becomes essential. This is
where Android devices, such as Android Head Units and smartphones,
can play a significant role. These devices offer distinct advantages due to
their extensive computational and connectivity capabilities compared to
traditional ECUs. In this context, this thesis aims to enhance vehicular
security using Android devices like head units and smartphones, which
have become ubiquitous in modern automobiles. The thesis explores
the potential of pairing-based cryptography in automotive security applications
and discusses four practical scenarios that may immediately
benefit from this modern type of cryptography. Two of these scenarios
are further investigated, proposing a secure vehicle access control
system based on identity-based and group signature schemes using modern
Android smartphones and a smartphone-based solution for securing
vehicle-to-vehicle communication using identity-based cryptography,
with identities extracted from license plates. Furthermore, leveraging the
extensive computation and communication capabilities of Android head
units, the thesis addresses efficient intrusion detection systems for the
CAN bus. The focus is on deploying these systems on Android-based devices
and integrating cloud connectivity to enhance computational power,
implement advanced IDS solutions and facilitate incident reporting.
