Sensor networks have opened up new opportunities in healthcare systems, which can transmit patient's condition to health professional's hand-held devices in time. The patient's physiological signals are very sensitive and the networks are extremely vulnerable to many attacks. It must be ensured that patient's privacy is not exposed to unauthorized entities. Therefore, the control of access to healthcare systems has become a crucial challenge. An efficient and secure authentication protocol will thus be needed in wireless medical sensor networks. In this paper, we propose a certificateless authentication scheme without bilinear pairing while providing patient anonymity. Compared with other related protocols, the proposed scheme needs less computation and communication cost and preserves stronger security. Our performance evaluations show that this protocol is more practical for healthcare system in wireless medical sensor networks.
传感器网络为医疗保健系统带来了新机遇，它能够及时将患者的病情传输到医疗专业人员的手持设备上。患者的生理信号非常敏感，而这些网络极易受到多种攻击。必须确保患者的隐私不会暴露给未经授权的实体。因此，对医疗保健系统的访问控制已成为一项关键挑战。无线医疗传感器网络因此需要一种高效且安全的认证协议。在本文中，我们提出了一种无需双线性配对的无证书认证方案，同时提供患者匿名性。与其他相关协议相比，该方案所需的计算和通信成本更低，并且具有更强的安全性。我们的性能评估表明，该协议对于无线医疗传感器网络中的医疗保健系统更为实用。
