Self-Adaptability in Secure Embedded Systems: An Energy-Performance Trade-Off
Securing embedded systems is a challenging and important research topic due to limited computational and memory resources. Moreover, battery powered embedded systems introduce power constraints that make the problem of deploying security more difficult. This problem may be addressed by improving the trade-off between minimizing energy consumption and maintaining a proper security level. This paper proposes an energy-aware method to determine the security resources consistent with the requirements of the system. The proposed solution is based on a multi-criteria decision mechanism, the Weighted Product Model (WPM), used to evaluate the relations between different security solutions and to select the appropriate one based on variable runtime requirements.
