Cyber-security for Engine ECUs: Past, Present and Future

2015-09-01
2015-01-1998
In this paper, we outline past, present and future applications of automotive security for engine ECUs. Electronic immobilizers and anti-tuning countermeasures have been used for several years. Recently, OEMs and suppliers are facing more and more powerful attackers, and as a result, have introduced stronger countermeasures based on hardware security. Finally, with the advent of connected cars, it is expected that many things that currently require a physical connection will be done remotely in a near future. This includes remote diagnostics, reprogramming and engine calibration.

Securing J1939 Communications Using Strong Encryption with FIPS 140-2

2017-03-28
2017-01-0020
Since 2001, all sensitive information of U.S. Federal Agencies has been protected by strong encryption mandated by the Federal Information Processing Standards (FIPS) 140-2 Security Requirements. The requirements specify a formal certification process. The process ensures that validated encryption modules have implemented the standard, and have passed a rigorous testing and review processes. Today, this same strong security protection has become possible for vehicle networks using modern, cost-effective encryption in hardware. This paper introduces the motivation and context for the encryption diagnostics security in terms of all vehicles in general, not just trucks which use SAE J1939 communications. Several practical scenarios for using such encryption hardware and the advantages of using hardware compared to software private-key encryption and public-key encryption are described.

Investigation of Vehicular Networks and its Main Security Issues

2014-04-01
2014-01-0336
Vehicular Network is an emerging and developing technology to improve traffic management and safety issues, and enable a wide range of value-added services such as collision warning/avoidance. Many applications have been designed to provide safety and comfort for passengers. This technology is a prolific area for attackers who will attempt to challenge the network with their malicious or rational attacks. In this paper we elaborate what a vehicular network is, different kinds of communication in this field, main mechanism and related parts and how vehicular networks work then we introduce some of its applications. After primary familiarity with this system we investigate to different type of attacker, more important security issues, How to secure vehicular networks (security requirements and some tools and methods to achieve secure vehicular networks), difficulties and providing viable security solutions, and at the end briefly explanation of related standards.

Challenges in the Regulatory Framework of Automated Driving

2019-01-09
2019-26-0097
Automated Driving (AD) is foreseen to be one of the major social and technological challenges in the coming years. Many manufacturers are developing new models with cutting-edge functionalities, which are not included in the scope of the current regulatory framework. Apart from demonstrating their know-how and expertise about AD, their willingness to sell their AD models in the European market is accelerating the rule-making system. However, which is the roadmap for the European regulatory framework? Policy makers and regulatory bodies are pushing their boundaries at all levels (national and international) in order to introduce modifications in existing regulations. These regulations will enable the introduction of these new functionalities into the market. Without decreasing the standards of safety and security, the implementation of a clear and harmonized regulatory framework and approval process is extremely needed.

Modelify: Semi-Automatic Conversion of Control Systems C Code to Simulink Models

2016-04-05
2016-01-0020
Over the last decade, the automotive industry has embraced model-based development for control systems. Many of these companies have chosen Simulink from MathWorks to design and simulate these models. However, a remaining issue is the fact that many control systems were initially written in C and are still being used. Some companies have attempted to manually convert these C systems to Simulink models but have found this method to be too costly, error-prone, and time consuming. EnSoft decided to tackle this problem by providing a semi-automated conversion using our Atlas for C tool. Atlas is a tool that maps software and creates a relation map for all parts of the program. It then offers the developer tools to query and visualize this graph. We have developed Modelify, a tool built on this framework that performs the necessary queries on a C project and creates equivalent Simulink models and subsystems.
