Direct end-to-middle authentication in cooperative networks
type: CreativeWork
description: Cooperative networks rely on user cooperation at the network layer to provide services, such as packet forwarding or shared access to other network resources like storage or Internet access. Examples of cooperative networks that build upon user contribution are ad-hoc networks, decentralized wireless mesh networks, micro-operator networks, wireless Internet access sharing networks or hybrids between these network types. However, while it enables new types of networks and services, the concept of cooperative network service provisioning also creates new attack possibilities for malicious and selfish users. For example, wireless multi-hop networks are particularly susceptible to attacks based on flooding and the interception of, tampering with, and forging of packets. Thus, reliable communication in such networks quintessentially depends on mechanisms to allow on-path devices, such as middleboxes, to verify the authenticity of network traffic and the identity of the communicating peers. Efficient standard authentication techniques for end-to-middle authentication typically assume the presence of shared keys within the network or rely on trusted third parties, such as online authentication servers. However, in cooperative scenarios, these approaches suffer from significant drawbacks in respect to functionality and efficiency. Moreover, the tight resource constraints of wireless routers and access points in cooperative scenarios make the use of more flexible but less efficient authentication techniques challenging. Hence, a careful selection of cryptographic components and the creation of new and flexible and efficient mechanisms is required to enable end-to-middle authentication in cooperative multi-hop networks. In this thesis, we address the problem of end-to-middle authentication on different levels of granularity, ranging from infrequent signaling events to rapid verification of high-bandwidth payload streams. The different security and performance requirements of …
