SPT-IoT 2021: The Fifth Workshop on Security, Privacy and Trust in the Internet of Things - Welcome and Committees

The emergence of the Internet of Things (IoT) and its adoption in many critical applications such as healthcare, smart cities, cyber-physical systems, and smart vehicles are very much a reality. This has raised unique security, privacy, and trust challenges to the adopters of IoT. The heterogeneous nature of the IoT devices as well as the computational constraints makes security, privacy, and trust an extremely challenging problem to solve. Nonetheless, security, privacy, and trust play a critical role for most, if not all, applications of IoT in domains such as surveillance, healthcare, security, transport, food safety, manufacturing, logistics, and supply chain management. Without effective solutions for security, privacy, and trust, reliable data fusion and mining, qualified services with context-aware intelligence and enhanced user acceptance and experience cannot be achieved. The IEEE PERCOM workshop on Security, Privacy, and Trust for IoT (SPT-IOT 2021) has continued to provide a forum that brings together researchers from academia as well as practitioners from industry, standardization bodies, and government to meet and exchange ideas on recent research and future directions for the IoT with a specific focus on IoT security, privacy, and trust. The novel and state of the art research submitted and presented in the workshop include privacy-preserving for big data in smart applications, the role of blockchain in security and privacy, data security and privacy in healthcare applications, trustworthiness, privacy in fog computing, and application of homomorphic encryption in mobile devices. The workshop received a good number of high-quality papers and after a rigorous review process taking into account relevance, technical contribution, and novelty, fourteen papers were accepted to be presented at the workshop. We sincerely thank the members of the Technical Programme Committee (TPC) for their hard work. We also sincerely thank all of the authors for choosing the workshop as an avenue to present their work.
