“…The problem is the computation load of the AES, which might have an undue influence on the response of the ECU. Wolf and Gendrullis [16] and the EVITA Project [17], [18] implemented a hardware security module (HSM) to accelerate the AES measures. However, even if a HSM is used, the cryptographic measure requires 60 clock cycles (at 100 MHz) for the encryption of one AES block [18].…”

Vehicle systems are controlled by embedded electronic devices called electronic control units (ECUs). These ECUs are connected together with network protocols. The Controller Area Network (CAN) protocol is widely implemented due to its high fault tolerance. However, the CAN is a serial broadcast bus, and it has no protection against security threats. In this paper, we propose a fast stream cipher based on a chaos neural network (CNN) that is able to generate pseudo-random numbers at a high speed, faster than that of the Advanced Encryption Standard, to protect ECUs on the CAN bus by encrypting CAN messages. We discuss the chaotic orbit of the CNN and statistical properties of pseudo-random numbers from the CNN. For a stream cipher, it is very important to share the symmetric key. We designed a symmetric key that is shared with ID-based encryption without the need to use digital certificates. We evaluated our method's performance with embedded boards and showed that the stream cipher is efficient for the embedded software of the ECU. Further, it does not need a hardware security module to accelerate the encryption.

“…HSMs may be classified into three types according to the field, in which they are used. [11] and [12]. They used a truncated 32-bit MAC considering the limited data payload of CAN data frames and explained that a 32-bit MAC is secure from collision attacks for 35 weeks due to the limited properties of an in-vehicle network (CAN bus load and bandwidth).…”

“…The E-safety Vehicle Intrusion proTected Applications (EVITA) project specifically defined security requirements and developed appropriate solutions for vehicular on-board networks [10]. Among these solutions, EVITA-MEDIUM-HSM was developed in order to implement a secure communication environment among ECUs [11], [12]. However, EVITA does not provide a specific security architecture for a particular communication protocol.…”

Vehicle-IT convergence technology is a rapidly rising paradigm of modern vehicles, in which an electronic control unit (ECU) is used to control the vehicle electrical systems, and the controller area network (CAN), an in-vehicle network, is commonly used to construct an efficient network of ECUs. Unfortunately, security issues have not been treated properly in CAN, although CAN control messages could be life-critical. With the appearance of the connected car environment, in-vehicle networks (e.g., CAN) are now connected to external networks (e.g., 3G/4G mobile networks), enabling an adversary to perform a long-range wireless attack using CAN vulnerabilities. In this paper we show that a long-range wireless attack is physically possible using a real vehicle and malicious smartphone application in a connected car environment. We also propose a security protocol for CAN as a countermeasure designed in accordance with current CAN specifications. We evaluate the feasibility of the proposed security protocol using CANoe software and a DSP-F28335 microcontroller. Our results show that the proposed security protocol is more efficient than existing security protocols with respect to authentication delay and communication load.Index Terms-Connected car, controller area network (CAN), in-vehicle network security, key management.

“…In [11], [12], pairwise HMAC based CAN message authentication is proposed; unfortunately, this approach incurs prohibitively high computational and communication overheads which are linear with the number of receivers. In the scheme described in [16], an ECU is elected as a central trusted master to establish a pairwise key between each pair of ECUs, and the key is used to authenticate communication between two ECUs. However, this scheme is not applicable to multicast communication which is typical in CAN bus systems.…”

Vehicles are being revolutionized by integrating modern computing and communication technologies in order to improve both user experience and driving safety. As a result, vehicular systems that used to be closed systems are opening up various interfaces, such as Bluetooth, 3G/4G, GPS, etc., to the outside world, thus introducing new opportunities for cyber attacks. It has been recently demonstrated that modern vehicles are vulnerable to several remote attacks launched through Bluetooth and cellular interfaces, allowing the attacker to take full control of the vehicle. The common root cause of these attacks is the lack of message authentication for the vehicle's internal bus system, called Controller Area Network (CAN). In this work, we propose VeCure -a practical security framework for vehicular systems, which can fundamentally solve the message authentication issue of the CAN bus. VeCure is designed to be compatible with existing vehicle system architectures, and employs a trust group structure and a novel message authentication scheme with offline computation capability to minimize online message processing delay and deployment cost. We built a proof-of-concept prototype on a testbed using Freescale's automotive development boards. The experimental results show that VeCure only introduces 50us additional delay to process a message, which is at least 20-fold faster than any existing solution.
