In this paper, we are interested in resource allocation for energy constrained and security-critical embedded systems. Tasks in such systems need to be successfully executed under certain energy budget and be robust against serious security threatens. Different to former energy minimal scheduling problem, we introduce a new optimization problem for a set of tasks with energy constraint and multiple security choices. We present a dynamic programming based approximation algorithm to minimize the security risk of the system while statistically guaranteeing energy consumption constraints for given energy slack ratio. The proposed algorithm is very efficient in both time and space dimensions, and achieves good solutions. Extensive simulations demonstrate the superiority of our algorithm over other approaches.
