Abstract
AbstractWith the rapid development of the Internet of Mobile Things (IoMT) and countless mobile devices connected to the Internet, problems of the IoMT computing paradigm, Mobile Cloud Computing (MCC) and Mobile Edge Computing (MEC), have been aggravated in terms of network congestion, high energy consumption, and huge investment cost. Dispersed computing utilize geographically distribute computing resources and the “code and data” strategy movement, reducing energy and investment costs and improving the performance of IoMT applications. However, security problems raise as the “code and data” movement among multiple devices. We analyze the security threats in IoMT dispersed computing and propose a secure dispersed computing scheme for IoMT. The proposed scheme improves the availability, integrity, confidentiality, and privacy of IoMT dispersed computing by a decentralized service discovery and distribution model and a security domain-based task offloading scheme. The experiment results prove the effectiveness of the proposed scheme.KeywordsDispersed computingBlockchainPrivacy
