“Within the set of many identifier-locator separation designs for the Internet, HIP has progressed further than anything else we have so far. It is time to see what HIP can do in larger scale in the real world. In order to make that happen, the world needs a HIP book, and now we have it.” – Jari Arkko, Internet Area Director, IETF One of the challenges facing the current Internet architecture is the incorporation of mobile and multi-homed terminals (hosts), and an overall lack of protection against Denial-of-Service attacks and identity spoofing. The Host Identity Protocol (HIP) is being developed by the Internet Engineering Task Force (IETF) as an integrated solution to these problems. The book presents a well-structured, readable and compact overview of the core protocol with relevant extensions to the Internet architecture and infrastructure. The covered topics include the Bound End-to-End Tunnel Mode for IPsec, Overlay Routable Cryptographic Hash Identifiers, extensions to the Domain Name System, IPv4 and IPv6 interoperability, integration with SIP, and support for legacy applications. Unique features of the book: All-in-one source for HIP specifications Complete coverage of HIP architecture and protocols Base exchange, mobility and multihoming extensions Practical snapshots of protocol operation IP security on lightweight devices Traversal of middleboxes, such as NATs and firewalls Name resolution infrastructure Micromobility, multicast, privacy extensions Chapter on applications, including HIP pilot deployment in a Boeing factory HOWTO for HIP on Linux (HIPL) implementation An important compliment to the official IETF specifications, this book will be a valuable reference for practicing engineers in equipment manufacturing companies and telecom operators, as well as network managers, network engineers, network operators and telecom engineers. Advanced students and academics, IT managers, professionals and operating system specialists will also find this book of interest.

Trust, Complexity and Control
An increasing reliance on the Internet and mobile communication has deprived us of our usual means of assessing another party’s trustworthiness. This is increasingly forcing us to rely on control. Yet the notion of trust and trustworthiness is essential to the continued development of a technology-enabled society. Trust, Complexity and Control offers readers a single, consistent explanation of how the sociological concept of ‘trust’ can be applied to a broad spectrum of technology-related areas; convergent communication, automated agents, digital security, semantic web, artificial intelligence, e-commerce, e-government, privacy etc. It presents a model of confidence in which trust and control are driven and limited by complexity in one explanatory framework and demonstrates how that framework can be applied to different research and application areas. Starting with the individual’s assessment of trust, the book shows the reader how application of the framework can clarify misunderstandings and offer solutions to complex problems. The uniqueness of Trust, Complexity and Control is its interdisciplinary treatment of a variety of diverse areas using a single framework. Sections featured include: Trust and distrust in the digital world. The impact of convergent communication and networks on trust. Trust, economy and commerce. Trust-enhancing technologies. Trust, Complexity and Control is an invaluable source of reference for both researchers and practitioners within the Trust community. It will also be of benefit to students and lecturers in the fields of information technology, social sciences and computer engineering.
