Mobile cloud computing (MCC) is a trending technology employed in several domains to overcome the limitations of mobile devices by using cloud capabilities. Communication between mobile devices and clouds is maintained via wireless media to make use of cloud services. Hence, MCC models show vital security issues related to many disciplines, especially authentication, privacy, and trust. Current MCC models lack the ability to secure and protect data, resources, communication channels, and authentication (client-to-cloud and cloud-to-client). MCC security issues have appeared mainly as a result of the integration between mobile devices and cloud computing. MCC issues represent critical challenges that must be addressed by model developers and practitioners. Enormous models have been proposed to enhance mobile cloud computing security issues, which makes it essential to systematically review and analyze them. In this paper, 73 relevant papers are systemically reviewed, among which 34 different models are analyzed against the known security issues that were either inherited from mobile and cloud computing technologies or emerged as a result of this integration. This study showed that (i) cloud-to-client authentication issues are disregarded by existing MCC models, (ii) existing MCC models tend to address some but not all security issues, and (iii) related MCC model surveys do not sufficiently address comprehensive MCC security issues (in each survey) such as securing and protecting data, resources, and communication channels. This paper provides an important resource regarding MCC security issues for model developers and practitioners for future research and designs.

移动云计算 (MCC) 是一种在多个领域中采用的趋势技术，旨在通过使用云功能来克服移动设备的局限性。移动设备与云之间的通信通过无线媒体进行维护，以利用云服务。因此，MCC 模型显示了与许多学科相关的重要安全问题，尤其是身份验证、隐私和信任。当前的 MCC 模型缺乏保护数据、资源、通信渠道和身份验证（客户端到云和云到客户端）的能力。MCC 安全问题的出现主要是由于移动设备和云计算之间的集成。MCC 问题代表了模型开发人员和从业人员必须解决的关键挑战。已经提出了大量模型来增强移动云计算的安全问题，这使得系统地审查和分析它们变得至关重要。在本文中，系统回顾了 73 篇相关论文，其中 34 种不同的模型针对已知的安全问题进行了分析，这些问题要么是从移动和云计算技术继承而来，要么是由于这种集成而出现的。这项研究表明 (i) 现有 MCC 模型忽略了云到客户端的身份验证问题，(ii) 现有 MCC 模型倾向于解决一些但不是所有安全问题，以及 (iii) 相关的 MCC 模型调查没有充分解决全面的问题MCC 安全问题（在每次调查中），例如保护和保护数据、资源和通信渠道。本文为模型开发人员和从业者未来研究和设计提供了有关 MCC 安全问题的重要资源。
