Security analysis of a machine-to-machine messaging system

Abstract

With the increasing popularity of small embedded devices, self-organizing and self-repairing networks are preferable. One such choice are peer-to-peer (P2P) systems which create an overlay network in the application layer to achieve a de-centralized and resilient communication system. Neuropil builds an encryption layer on top of a Pastry/Tapestry P2P network to provide confidentiality and integrity to a certain degree. This thesis analyzes the protocol used by Neuropil in its default implementation and explores some possibilities to improve the security.
