The ubiquitous nature of the Internet is enabling a new generation of - pUcations to support collaborative work among geographically distant users. Security in such an environment is of utmost importance to safeguard the pri vacy of the communication and to ensure the integrity of the applications. 'Secure group communications' (SGC) refers to a scenario in which a group of participants can receive and send messages to group members, in a way that outsiders are unable to glean any information even when they are able to intercept the messages. SGC is becoming extremely important for researchers and practitioners because many applications that require SGC are now widely used, such as teleconferencing, tele-medicine, real-time information services, distributed interactive simulations, collaborative work, grid computing, and the deployment of VPN (Virtual Private Networks). Even though considerable research accomplishments have been achieved in SGC, few books exist on this very important topic. The purpose of this book is to provide a comprehensive survey of principles and state-of-the-art techniques for secure group communications over data net works. The book is targeted towards practitioners, researchers and students in the fields of networking, security, and software applications development. The book consists of 7 chapters, which are listed and described as follows.

Securing network communications is a major challenge facing the Internet today.Due to the point-to-point communication model of TCP/IP architecture, at the time when security became a necessity, the channel-based security model, represented by Secure Sockets Layer (SSL) and its successor Transport Layer Security (TLS), was applied to secure network communication between hosts. However, designed for synchronous channels over the network infrastructure, this security solution does not fit many emerging network scenarios that require asynchronous communication. In addition, with the growth of content delivery applications, the mismatch between what application needs, i.e., secured data, and what is provided by the channel-based security model, i.e., secured channels, has also been observed in recent years. A newly proposed architecture, Named Data Networking (NDN), has been developed over the past decade.Departing from TCP/IP's network model, NDN considers named secured data, instead of channels, as the building block of the communication, and provides an alternative to today's security model by securing data directly. Not relying on the network context, a piece of named secured data can be forwarded, cached, and reused without breaking the security primitives. To deliver named secured data at the network layer, NDN uses a stateful forwarding plane and forwards packets by names instead of IP addresses. Under this background, there is an urge to understand the difference between the conventional channel-based security model and the new data-centric security model, and explore how to utilize the new way of doing network security to address today's security issues.For this purpose, we first revisit the key concepts of network security from the application's perspective and analyze the main features of the two security models. Then, we present our design of a number of security solutions built over NDN's named secured data, including (i) a self-contained smart home control system, (ii) a DDoS mitigation mechanism that supports fine-grained traffic throttling, (iii) a distributed ledger system for distributed rooftop solar energy system, (iv) a multiparty signing and verification toolset, and (v) a secured data prefetching system for vehicular networking. We also describe two security solutions built on to the application level for (i) asynchronous and privacy-preserving single sign-on (SSO) and (ii) reliable leaker identification in sensitive data sharing, respectively.While not directly built over NDN because of today's deployment constraints, they follow the notion of the data-centric security model. Through the design discussion of these systems, we confirm the unique advantages of the data-centric security model and demonstrate how the new security model and especially, NDN's named secured data, can be applied to address some challenges that are intractable to the channel-based security model.

Named Data Networking (NDN) is a proposed Internet architecture, which changes the network communication model from "speaking to a host" to "retrieving data from network". Such data-centric communication model requires a data-centric security model, which secures data directly rather than authenticating the host where data is retrieved from and securing the channel through which data is delivered, so that data can be safely distributed into arbitrary untrusted storage and retrieved over untrusted network. The data-centric security model consists of two parts: data-centric authenticity and data-centric confidentiality. NDN achieves data-centric authenticity by mandating per packet signature, and data-centric confidentiality by data encryption. While the idea is straightforward, we observed that usability of data-centric security of NDN prevents developers from enabling security in their applications. This dissertation presents a security framework to automate data-centric security of NDN and reduce the enabling overhead. To achieve that, we designed NDN certificate system to facilitate public key distribution in NDN; we designed Trust Schema, a name-based policy language to specify trust model, in order to automate fine-grained data authentication; we designed a timestamp service DeLorean to address the authenticity problem of archival data; and we also designed an access control protocol Name-based Access Control to automate data-centric confidentiality at fine granularities.
