ECU might request for a specific sensor’s data. MECU, then only the communications of that domain can be impeded. An ECU sends data to its MECU to store it. The thesis starts by developing a hybrid threat model that combines multiple existing threat modeling approaches to define a more comprehensive one. This model defines (1) the various potential groups of attackers, which may threaten the vehicular system and their capabilities, (2) the potential targets (i.e., assets) of these groups and the various vulnerabilities that they include, and (3) the security requirements for these targets which should be considered to prevent the attacker from compromising them. However, all communication between Electrical Control Unites (ECU) still suffer from security drawbacks like highly processing time or preserving confidentiality, integrity and authenticity. In this paper, we propose a Blockchain based Framework for sEcuring smaRt vehicLes (B-FERL). While these improvements have increased the safety of the automotive system, they have vastly expanded the attack surface of the vehicle and opened the door for new potential security risks. 822 0 obj Published: November, 2016; Format: Electronic (PDF) Number of pages: 85; Industry: Sensors & Controls In our previous work, we presented a lightweight instantiation of a BC particularly geared for use in IoT by eliminating the Proof of Work (POW) and the concept of coins. 0000001682 00000 n solve this problem, the vehicle industry has started to use Unshielded Twisted P. model to connect cameras and the surround view system.
