Security, trust and privacy risks, responses, and solutions for high-speed smart cities networks: A systematic literature review

High-speed networks are utilized to satisfy user demands by using cloud and edge services. Due to the heterogeneous nature of these networks, security, trust, and privacy are the significant challenges for these networks. These networks are vulnerable to various security threats, lack of trustworthy devices, and user privacy concerns due to architectural complexities, diversity of protocols, and dynamic network topologies. This Systematic Literature Review (SLR) explores these networks in terms of technologies, edge and cloud services, security, trust and privacy concerns. Torress-Carrion methodology is used as a guideline to conduct this review to find the recent security, trust and privacy concerns. The attacks related to each area and their solutions are discussed to evaluate their strengths and weaknesses. The various existing technologies explore like Blockchain, encryption, hashing, and fuzzy logic. In addition, the trust evaluation and user privacy provision techniques are also discuss. This SLR also explores the methods designed for different communication layers against the various multilingual passive/active attacks like Sybil, Denial of Service (DoS), Distributed Denial of Service (DDoS), and Man in the Middle (MITM). This SLR will provide a direction to new researchers in the field of security, trust, and privacy to design more efficient and effective solutions to deal with new security challenges.(c) 2023 The Author(s).
