Abstract
The European Telecommunications Standards Institute (ETSI) is currently standardizing a new concept - namely Machine-to-Machine-that allows sensors and meters to communicate together with limited human intervention. One of the fundamental requirements of this new technology is to assure secure and self-organized communication over the existing network infrastructure. Thus, we need to build a secure overlay network between sensors and meters deployed over the Internet. The Internet Engineering Task Force (IETF) has recently standardized a new protocol named the Host Identity Protocol which decouples node identity from its address by introducing a secure cryptographically namespace as a node identifier. In this paper, we propose to combine an enhanced version of the HIP protocol with the Machine-to-Machine paradigm in order to build a secure overlay network over the Internet. We first evaluate analytically the signaling cost of our protocol. Then, we implement and evaluate our solution with the OMNeT++ network simulator.
