Preface vi Authentication and Confidentiality Part I of Security in Ad hoc and Sensor Networks begins with a discussion on two critical services, authentication and confidentiality. Authentication seeks to prove that a device is who it purports to be, while confidentiality aims to preserve the privacy of data from eavesdroppers. Chapter 1 highlights the requirements needed to provide these services explicitly for ad hoc networks. An analysis of the strengths, weaknesses, and overhead are detailed for numerous symmetric, asymmetric, and collaborative authentication solutions. Similarly, the authors also provide analysis for different types of confidentiality schemes that have been proposed in the literature. The confidentiality schemes described go a bit further than just efficiently encrypting payloads to protect privacy of data, but also seek to preserve the secrecy of the participants of the flow. Chapter 1 concludes with a vulnerability assessment of the wireless security protocols 802.1X and 802.11i, the de facto standards for authentication and confidentiality. The underpinning of many security services, especially authentication and confidentiality, is a secret key. Consequently, mechanisms for establishing, distributing, and revoking keys are critical to the operation of these services. This is particularly challenging for ad hoc and sensor networks because nodes enter/leave the network dynamically and there is no central authority for facilitating these mechanisms. Chapter 2 surveys several key distribution schemes while considering different factors that influence the strategy of a scheme. For instance, implementation of the key distribution scheme may depend on the layer of the protocol stack at which the scheme will operate and on whether the security service is intended for prevention or detection measures. The author of Chapter 2 also evaluates various key distribution schemes based on the storage requirements, network communication bandwidth utilization, and out-of-band communication overhead. Chapter 3 proposes a key pre- distribution framework that exploits the observation that nodes in the same group are usually close to each other after deployment, a characteristic that relaxes the need to discover the correct location of nodes post deployment.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
