Data privacy and security are a major concern in any field mainly mobile commerce, Internet of Thing (IoT), and wireless data communication. Classical security is particularly based on encryption to protect data confidentiality, integrity, non repudiation and availability. However, mobile devices are limited in processing, battery life and communication bit rate. Therefore, many security protections are not used in order to save battery life. A new paradigm must be carried out to establish a framework capable to be energy aware when applying a security mechanism. In this paper, we present our Security Adaptation Reference Monitor (SARM). It is based on an autonomic computing security looped system, which fine-tunes security means based on the monitoring of the context including the user environment and energy consumption aspects. Thereafter, we investigate the cost of security and wireless communication related to battery consumption.
