The security of wireless body sensor network (BSN) is very important to telemedicine and m-healthcare, and it still remains a critical challenge. This paper presents a novel key distribution solution which allows two sensors in one BSN to agree on a changeable cryptographic key. A previously published scheme, fuzzy vault, is firstly applied to secure the random cryptographic key generated from electrocardiographic (ECG) signals. Simulations based on ECG data from MIT PhysioBank database, produce a minimum half total error rate (HTER) of 0.65%, which demonstrates our key distribution solution is promising compared with previous method, with HTER of 4.26%.
无线人体传感器网络（BSN）的安全性对远程医疗和移动医疗保健非常重要，并且仍然是一个关键挑战。本文提出了一种新颖的密钥分发解决方案，该方案允许一个BSN中的两个传感器就一个可变的加密密钥达成一致。首先应用先前发表的模糊保险库方案来保护从心电图（ECG）信号生成的随机加密密钥。基于麻省理工学院生理信号数据库的心电图数据进行的模拟产生了0.65%的最小半总错误率（HTER），这表明我们的密钥分发解决方案与先前方法相比很有前景，先前方法的HTER为4.26%。
