在智能汽车系统、物联网 (IoT) 和工业控制系统等新兴应用中，由于 MAC 输出尺寸较大，无法使用传统的消息认证码 (MAC) 来提供消息认证和完整性。解决这个问题的一个简单但幼稚的解决方案是采用截断的 MAC，这会牺牲加密强度以换取减少的通信开销。在本文中，我们通过提出一种称为累积消息认证码（CuMAC）的消息认证新方法来解决这个问题，该方法由两个独特的过程组成：聚合和累积。在聚合中，发送方通过使用系统编码过程从多个 MAC 段生成紧凑的身份验证标签。在累积过程中，接收方通过验证身份验证标签并收集其中编码的底层 MAC 段来累积加密强度。通过这两个过程的体现，CuMAC 使接收器能够在加密强度和认证标签处理延迟之间实现有利的权衡。我们对CuMAC在低功耗广域网和车载控制器局域网这两个实际应用中进行了综合评估。我们的评估方法包括模拟以及 CuMAC 在真车上的原型实现。
In emerging applications, such as intelligent automotive systems, Internet-of-Things (IoT) and industrial control systems, the use of conventional message authentication codes (MACs) to provide message authentication and integrity is not possible due to the large size of the MAC output. A straightforward yet naive solution to this problem is to employ a truncated MAC which undesirably sacrifices cryptographic strength in exchange for reduced communication overhead. In this paper, we address this problem by proposing a novel approach for message authentication called Cumulative Message Authentication Code (CuMAC), which consists of two distinctive procedures: aggregation and accumulation. In aggregation, a sender generates compact authentication tags from segments of multiple MACs by using a systematic encoding procedure. In accumulation, a receiver accumulates the cryptographic strength by verifying the authentication tags and collecting the underlying MAC segments encoded in them. Embodied with these two procedures, CuMAC enables the receiver to achieve an advantageous trade-off between the cryptographic strength and the latency in processing of the authentication tags. We have carried out comprehensive evaluations of CuMAC in two real-world applications: low-power wide-area network and in-vehicle controller area network. Our evaluation methodology included simulations as well as a prototype implementation of CuMAC on a real car.
