An Efficient Key Management Solution for Personal Network Federations

Personal network federation (PN-F) aims to provide secure interactions between a subset of devices of different personal networks (PN) for achieving a common goal or providing some services in collaborative environments. Security and privacy is one of the major concerns in the development and acceptance of PN-F like collaborative networks and as any other security architecture, the key management is the corner stone of any possible solution. In this paper, we provide security mechanisms and protocols for key exchange and key management in PN federations and specify how the established keys can be used to secure communications in different layers.
