Internet of Things (IoT) enables Internet-connected devices to maintain seamless connections between people, networks, and physical services. It allows billions of objects in the physical world, as well as virtual environments, to exchange data with each other in an autonomous way, which is the basis of smart ecosystems, including automotive, healthcare, smart cities, smart homes, logistics, and environmental monitoring. With their connection capability, cyber-physical systems (CPS) comprise interacting digital, analog, physical, and human components engineered for functioning via integrated physics and logic. These systems provide the foundation of critical infrastructures, form the basis of emerging and future smart services, and improve quality of life in many domains.

In the context of IoT and CPS, and given the broadcast nature of wireless channels, security and privacy have become of utmost concern. For instance, because of increasingly skilled cybercriminals, transmitting confidential data over IoT/CPS remains a challenging task in both academia and industry. Even more, with the global rollout of 5G systems, which will eventually lead to an even tighter integration of the legacy internet and IoT, there is a greater need to safeguard IoT and CPS and adequately defend such systems against the plethora of modern external and insider threats.

This Special Issue focuses on IoT and CPS security and privacy with the aim to solicit the latest technologies, solutions, case studies, and prototypes on this topic.

Topics of interest include, but are limited to, the following:

- Secure data management in IoT/CPS
- Intrusion detection and prevention, firewalls, and packet filters
- Malware, botnets, and distributed denial of service
- IoT/CPS communication privacy and anonymity
- Forensics techniques
- Public key infrastructures, key management, and credential management
- Secure routing in IoT/CPS
- Security and privacy in pervasive and ubiquitous computing
- Security and privacy for IoT/CPS applications.
- Disaster recovery in IoT/CPS communication
- Reliability of IoT/CPS communication

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
