In this paper we propose a framework for the analysis of the security in peer-to-peer Session Initiation Protocol based infrastructures. The proposed approach defines a game theoretical model for both an attacker as well as the defender and uses the Nash equilibrium to derive optimal attack and defensive strategies for both entities. We address the specific threats related to SPam over Internet Telephony, flooding and non-cooperative behavior and assess defensive mechanisms based on thresholds and redundant retransmissions. The paper summarizes the main results based on extensive Monte-Carlo simulations of this game.
