초록
Various studies have been conducted on a secret key exchange using the inter-pulse interval (IPI) extracted from a pulse wave. The IPI-based key exchange method uses a point where the body can measure an IPI of similar value anywhere. The IPI measured to generate the secret key shares the error correction code between biometric sensors and generates the key using the corrected IPI. Peak misdetection negatively affects key generation because the IPI does not consistently match. In this paper, we propose a method to detect misdetection and recover IPI using thresholds. The proposed method reduces the cost of communication compared to the previous method, which is not only energy efficient but also key generating. The efficiency of the recovery method is also demonstrated. Tests results show the total number of IPI recoveries is 19, while the key generation rate is 99.4%.
