Guest Editorial: Special Issue on Security and Privacy of Distributed Algorithms and Network Systems

The articles in this special issue focus on security and privacy of distributed algorithms and network systems. The integration of computation, communication, and control technologies has led to the widespread emergence of large scale engineering systems. These network systems are deployed in numerous fields, including electric and smart grids, transportation and smart cities, health-care and manufacturing, and so forth. Due to the rapid growth in number of geographically deployed units, such as sensors, computers and controllers, traditional centralized control and optimization algorithms may not be efficient, robust, or even applicable at all. Instead, distributed control and optimization algorithms offer a promising and desirable approach to operate and guarantee the well functioning of network systems. The aim of this special issue is to provide a window into the recent developments of the fundamentals and applications of security and privacy of distributed algorithms in network systems.
