Adaptive Optimization of TLS Overhead for Wireless Communication in Critical Infrastructure

With critical infrastructure increasingly relying on wireless communication, using end-to-end security such as TLS becomes imperative. However, TLS introduces significant overhead for resource-constrained devices and networks prevalent in critical infrastructure. In this paper, we propose to leverage the degrees of freedom in configuring TLS to dynamically adapt algorithms, parameters, and other settings to best meet the currently occurring resource and security constraints in a wireless communication scenario. Consequently, we can make the best use of scarce resources to provide tightened security for wireless networks in critical infrastructure.
