Intel Software Guard Extensions in Internet of Things Scenarios: A Systematic Mapping Study
Newton C. Will, Dalton Cézane Gomes Valadares, Danilo F. S. Santos, Ângelo Perkusich · 2021
Due to the Internet of Things (IoT) devices' processing and memory constraints, the processing and analysis of data acquired by such devices are generally performed in a fog or cloud environment, which offers more processing power. When delegating data processing to third parties, it is necessary to ensure their confidentiality and their owners' privacy, which can be achieved using a Trusted Execution Environment, such as Intel SGX. In this paper, we present a systematic mapping study to review recent works related to the use of Intel SGX architecture in IoT scenarios. We conduct the study by selecting 35 papers published between 2017 and 2020 and providing a comprehensive overview of the application scenarios and solutions when combining Intel SGX and the IoT paradigm.
