Although there is a strong need to deploy secure communications in home networks and for Machine-to-Machine (M2M) environment, to our knowledge the impact of authenticated encryption migration has not been evaluated yet. As the security performance issue is especially critical for wireless environment, this paper measures the effect of the security settings on the Quality of Service (QoS) for encrypted communications in a home network environment. Security settings include different configurations of IPsec tested over several hardware platforms. The QoS is evaluated based on CPU time and elapsed time for downloading different sized files.
