CVCC, a hybrid technology to exploit the computing resources among the cloud, roadside infrastructure, and vehicles, has received considerable attention in recent years. Different from traditional cloud computing, CVCC additionally makes use of underutilized vehicular resources, which can make rich applications and services possible even when neither cloud nor roadside infrastructure is available. CVCC is popular today; however, the security and privacy issues are still the main obstacle in CVCC for its full implementation. To deal with security and privacy challenges, advanced cryptographic primitives have become indispensable parts of CVCC. Among them, the pairing-based cryptographic primitive is of particular interest. However, the pairing computation is usually time-consuming. Therefore, it is beneficial for vehicles to outsource pairing computations especially when the underlying pairing computations are massively needed. In this article, we devote our attention toward the security challenges and efficiency requirements of outsourcing pairing from vehicles to vehicles in CVCC. Specifically, we give a pairing outsourcing protocol for illustration, which indicates that secure and effective pairing outsourcing in CVCC is possible. Furthermore, we also identify some future research directions in secure CVCC.

车联网云计算中的安全外包计算


CVCC是一种利用云、路边基础设施和车辆之间的计算资源的混合技术，近年来受到了广泛的关注。与传统云计算不同，CVCC还利用了未充分利用的车辆资源，即使在云和路边基础设施都不可用的情况下，也可以使丰富的应用和服务成为可能。 CVCC 如今很流行；然而，安全和隐私问题仍然是CVCC全面实施的主要障碍。为了应对安全和隐私挑战，先进的密码原语已成为 CVCC 不可或缺的一部分。其中，基于配对的密码原语特别令人感兴趣。然而，配对计算通常非常耗时。因此，对于车辆来说，外包配对计算是有利的，特别是当大量需要底层配对计算时。在本文中，我们将重点关注 CVCC 中车辆与车辆之间外包配对的安全挑战和效率要求。具体来说，我们给出了一个配对外包协议进行说明，这表明CVCC中安全有效的配对外包是可能的。此外，我们还确定了安全 CVCC 的一些未来研究方向。
