本文旨在说明,通过使用一种名为“基于属性的加密”(ABE)的加密方案,可以提高汽车场景中空中更新功能的安全性,该加密方案为空中(OTA)完成的软件/固件更新赠款保密性。我们表明,ABE是无缝集成到最先进的解决方案,关于OTA更新显示,ABE集成的开销在计算时间和存储方面是可以忽略不计的w.r.t. OTA过程引入的其他开销,也证明可以以最小的成本增强安全性。为了支持我们的主张,我们报告了在Xilinx ZCU 102评估板上实施所提出的ABE OTA技术的实验结果,该评估板是面向汽车的硬件/软件平台,配备了Zynq UltraScale+ MPSoC芯片,该芯片代表了真实的汽车电子控制单元(ECU)的计算能力。
This paper aims to show that it is possible to improve security for over the air update functionalities in an automotive scenario through the use of a cryptographic scheme, called “Attribute-Based-Encryption” (ABE), which grants confidentiality to the software/firmware update done Over The Air (OTA). We demonstrate that ABE is seamlessly integrable into the state of the art solutions regarding the OTA update by showing that the overhead of the ABE integration in terms of computation time and its storage is negligible w.r.t. the other overheads that are introduced by the OTA process, also proving that security can be enhanced with a minimum cost. In order to support our claim, we report the experimental results of an implementation of the proposed ABE OTA technique on a Xilinx ZCU102 evaluation board, which is an automotive-oriented HW/SW platform that is equipped with a Zynq UltraScale+ MPSoC chip that is representative of the computing capability of real automotive Electronic Control Units (ECUs).
