The increasing attacks against the Internet of Things (IoT) systems are a determining factor to focus attention on IoT security. The use of Smart Cards (SCs) to protect these systems is pertinent, as they are resistant to physical attacks, portable, and have a relatively low cost. Nonetheless, SC processing and its memory capacity are not sufficient to meet IoT demands. Therefore, the use of multiple clustered SCs seems a promising solution. We present a solution based on the use of the Field Programmable Gate Array hardware capable of managing multiple SCs, chosen for its ability to parallelize tasks. In this work, a Smart Card Cluster (SCC) is applied to ensure message authenticity and integrity through hardware signing. For instance, with only three SCs, a SCC supports signing about 26 messages per minute. In this paper, we describe the design of a SCC that is modular, portable, flexible and cost-effective. Through experiments, we demonstrate that our SCC outperforms existing solutions by as much as 69%, while the cost remains relatively low.
