In this paper we consider distributed embedded systems in which privacyor confidentiality of the internal communication is critical, andpresent an approach to optimizing cryptographic algorithms under stricttiming constraints. We have developed a technique to search for the bestsystem-affordable cryptographic protection for the messages transmittedover the internal communication bus. Towards this, we formulate theoptimization technique in Constraint Logic Programming (CLP), whichreturns optimal results. However, CLP executions are computationallyexpensive and hence, we propose an efficient heuristic as analternative. Extensive experiments demonstrate the efficiency of theproposed heuristic approach.
