The Workshop on Secure Network Protocols (NPSec) is a top workshop focusing on cutting-edge research with a broad range of topics related to secure network protocols. NPSec 2014 is a one-day event held in conjunction with the 22nd IEEE International Conference on Network Protocols (ICNP 2014). NPSec 2014 focuses on two exciting areas related to secure network protocols. The first focus is on the development and analysis of networking protocols for the secure operation of various network infrastructures, including both today's Internet and future Internet architectures, wireless and mobile networking, cloud-based networking, peer-to-peer and overlay networks, online social networking, and Internet of things. Papers about new secure protocols, security enhancements to existing protocols, or protocol analysis (such as new attacks on existing protocols) are all welcome. The second focus is on employing such secure network protocols to create or enhance network applications, such as those related to the Web, online social networking, online gaming, or cloud-based applications.
