The thesis addresses this issue by using the Red-Zone principle, whereby a tighter inner security envelope alerts the security system of a potential compromise before an actual security violation occurs. Thus, this paper proposes an edge computing-based security protocol with fine-grained attribute-based encryption using a hash function, symmetric-based cryptography, and reconfigured cryptographic scheme. cess control, we add another ECU (ECU3) under MECU1. on vehicle engineers whether one of the ECUs data should be stored or not.

The SmartGate system allows car owners to connect a smartphone to the car. In brief, the main contributions of this thesis are as follows: curve-based PKE among ECUs to transfer data confidentially. more than 256 kilobytes of data can be transmitted within 10 ms. the figure, we can observe when the size of the data is from 1 b, size is 2 kilobytes or larger, the end to end delay increases significan, when the data size is 256 kilobytes, the av, next data size is 512 kilobytes, which tak.

Similar to Docker experiments, ECU1 is permitted to send a data request to ECU2. Although research efforts have been made to secure in-vehicle networks, most of them focused on defining security requirements, or presenting attack scenarios without providing any feasible solution. In addition, we propose the adoption of an identity-based access control in Mother ECUs (MECU, also known as a domain controller) to control the communication permissions. read ECU2’s sent data from the communication bus. are necessary for insurance companies to decide the insurance premium for the driver. although the differences among CAN networks are, for example, their different.

Oxygen sensor is one of the types of automobile computer chips that form an important part of the engine fuel control feedback loop. We also provide discussions on the security of the architecture against important attacks. With consideration of the facts aforementioned, this work addresses resource problems by offloading secure operations to high-performance devices, and uses attribute-based access control to ensure the confidentiality of messages from attackers and unauthorized users. The car won’t start at all. As a result, if an adversary can compromise one of the ECUs, then the adversary will be able to access and exploit data of other important ECUs. execution on the electronic control units (ECU) in automotive vehicles via various interfaces such as the Bluetooth interface and the telematics unit. and the host machine’s processor speed is 2.3 GHz. Moreover, an adversary can modify the stored data of an important ECU, if it is compromised. What is an ECU In the Automobile industry an electronic control unit (ECU) is an embedded electronic device, basically a digital computer, that reads signals coming from sensors placed at various parts and in different components of the car and depending on this information controls various important units e.g. Also, quantitative evaluations in an emulated scenario show that B-FERL ensures a suitable response time and required storage size compatible with realistic scenarios. ��Ț@R 5u���j� �6ը)˜�8����>AO��lGh�UP�F�ZRg$$� 4� o;$��0{����b��\ Electronic fuel injection (EFI) • allows precise and fast control of fuel injected • by control of the Zon-time period of the solenoid operated injectors (spray nozzle) and plunger. sensors, generates an ECU data transaction (ECU transaction), and sends it to the, MECU.
