EC-SVC:基于边缘计算的安全CAN总线车载通信和细粒度访问控制

EC-SVC: Secure CAN Bus In-Vehicle Communications with Fine-grained Access Control Based on Edge Computing

Donghyun Yu, Ruei-Hau Hsu, Jemin Lee

摘要:

车内通信最初不是为车辆和外部系统之间的消息交换而设计的。因此,消息保护的安全性设计不足。此外,内部设备没有足够的资源来处理额外的安全操作。然而,由于广播消息的车载网络的特性,必须确保向特定接收器的安全消息传输。考虑到上述事实,这项工作通过将安全操作卸载到高性能设备来解决资源问题,并使用基于属性的访问控制来确保来自攻击者和未授权用户的消息的机密性。此外,我们重新配置了现有的基于访问控制的加密技术,以解决使用边缘计算和基于属性的访问控制所产生的新漏洞。因此,本文提出了一个基于边缘计算的安全协议,细粒度的基于属性的加密,使用哈希函数,基于密码学,和重新配置的加密方案。此外,本文还对重构后的密码方案和安全协议进行了形式化证明,并利用CANoe软件对所提出的安全协议进行了多方面的可行性评估。

英文摘要:

In-vehicle communications are not designed for message exchange between the vehicles and outside systems originally. Thus, the security design of message protection is insufficient. Moreover, the internal devices do not have enough resources to process the additional security operations. Nonetheless, due to the characteristic of the in-vehicle network in which messages are broadcast, secure message transmission to specific receivers must be ensured. 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. In addition, we reconfigure existing access control based cryptography to address new vulnerabilities arising from the use of edge computing and attribute-based access control. 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. In addition, this work formally proves the reconfigured cryptographic scheme and security protocol, and evaluates the feasibility of the proposed security protocol in various aspects using the CANoe software.
