The rapid development of Internet-of-Things (IoT) techniques in 4G/5G deployments is witnessing the generation of massive amounts of data which are collected, stored, processed, and presented in an easily interpretable form. Analysis of IoT data helps provide smart services such as smart homes, smart energy, smart health, and smart environments through 4G and 5G technologies. At the same time, the threat of the cyberattacks and issues with mobile internet security is becoming increasingly severe, which introduces new challenges for the security of IoT systems and applications and the privacy of individuals thereby. Protecting IoT data privacy while enabling data availability is an urgent but difficult task.

Data privacy in a distributed environment like IoT can be attained through secure multiparty computation. An emerging area of potential applications for secure computation is to address privacy concerns in data aggregation and analysis to match the explosive growth of the amount of IoT data. However, the inherent complexity of IoT systems really complicates the design and deployment of efficient, interoperable, and scalable secure computation mechanisms. As a result, there is an increasing demand for the development of new secure computation methods and tools which can fill in the gap between security and practical usage in IoT.

This featured topic will benefit the research community by identifying challenges and disseminating the latest methodologies and solutions to secure computation on 4G and 5G enabled IoT data. Its objective is to publish high-quality articles presenting open issues, algorithms, protocols, policies, frameworks, standards, and solutions for secure computation techniques related to IoT. All received submissions will be sent out for peer review by at least two experts in the field and evaluated with respect to relevance to the special issue, level of innovation, depth of contributions, and quality of presentation. Reviews and case studies, which address state-of-art research and state-of-practice industry experiences, are also welcomed. Guest  Editors will make an initial determination of the suitability and scope of all submissions. Papers that either lack originality and clarity in presentation or fall outside the scope of the special issue will not be sent for review and the authors will be promptly informed in such cases. Submitted papers must not be under consideration by any other journal or publication.
