This book constitutes the refereed proceedings of the 4th European Workshop on Security and Privacy in Ad hoc and Sensor Networks, ESAS 2007, held in Cambridge, UK, in July 2007.

The 17 revised full papers presented were carefully reviewed and selected from 87 submissions. The papers present original research on all aspects of security and privacy in wireless ad hoc and sensor networks and addressing current topics of network security, cryptography, and wireless networking communities. The papers are organized in topical sections on device pairing, key management, location verification and location privacy, secure routing and forwarding, physical security, as well as detection of compromise, and revocation.

This book constitutes the refereed proceedings of the 5th European Symposium on Research in Computer Security, ESORICS 98, held in Louvain-la-Neuve, Belgium, in September 1998.
The 24 revised full papers presented were carefully reviewed and selected from a total of 57 submissions. The papers provide current results from research and development in design and specification of security policies, access control modelling and protocol analysis, mobile systems and anonymity, Java and mobile code, watermarking, intrusion detection and prevention, and specific threads.

The two-volume set, LNCS 9878 and 9879 constitutes the refereed proceedings of the 21st European Symposium on Research in Computer Security, ESORICS 2016, held in Heraklion, Greece, in September 2016. The 60 revised full papers presented were carefully reviewed and selected from 285 submissions. The papers cover a wide range of topics in security and privacy, including data protection: systems security, network security, access control, authentication, and security in such emerging areas as cloud computing, cyber-physical systems, and the Internet of Things.
