An Identity-Based Key Management Framework for Personal Networks

Personal networks and PN federations are new networking paradigms that merge concepts from ad hoc, P2P and wireless networks, built around user's needs. Even though they are a promise of a practical achievement of ubiquitous computing, managing security associations in these frameworks proves to be a challenge. We present in this paper a security architecture, including a uniform personal namespace using crypto-based identifiers and a key management scheme based on identity-based cryptography. We also provide an evaluation of our scheme, in terms of computation complexity, communication cost and security.
