In this work, we evaluate the use of multiple sensors for secret key extraction. We find that the key generation rate increases linearly with the number of nodes. We show that the use of multiple nodes causes a significant mismatch in the extracted bits. We address the high bit mismatch problem by adding an iterative distillation stage to the key extraction process.
