| Description | Wireless sensor networks with a large number of cheap, low-power interconnected devices bring up challenging tasks when considering the security of their communications. We have previously proposed two novel approaches to updating cryptographic link keys between individual nodes - entropy-driven secrecy amplification and entropy crowdsourcing. In this paper, we focus on evaluating the protocols and their optimal settings and benefits. The comparison of individual protocols is made both on a real network and in simulation. Based on the results, we argue that none of the evaluated protocols outperform the others globally in all possible scenarios. Still, if we focus only on one specific case, we can optimize the protocol selection. Based on the evidence from experimental data, we, therefore, suggest the use of multiple different protocols with the option of dynamically switching in between them. |
