Special Session on "Security in Networked and Distributed Systems" aims to bring together researchers and practitioners involved in multiple disciplines concerning security in distributed systems to exchange ideas and to learn the latest developments in this important field. We will focus on issues related to network and distributed system security, such as authentication, access control, confidentiality, integrity, availability, privacy, dependability and sustainability of distributed systems. Previously unpublished papers offering novel research contributions to the theoretical and practical aspects of security in distributed systems are solicited for submission.
