Thanks to the widespread availability of Fifth Generation (5G) wireless connectivity, it is now possible to provide preventative or proactive healthcare services from any location and at any time. As a result of this technological improvement, Wireless Body Area Networks (WBANs) have emerged as a new study of research in the field of healthcare in recent years. WBANs, on the one hand, intend to gather and monitor data from the human body and its surroundings; on the other hand, biomedical devices and sensors interact through an open wireless channel, making them exposed to a range of cyber threats. However, WBANs are a heterogeneous-based system; heterogeneous cryptography is necessary, in which the transmitter and receiver can employ different types of public key cryptography. This article proposes an improved and efficient heterogeneous authentication scheme with a conditional privacy-preserving strategy that provides secure communication in WBANs. In the proposed scheme, we employed certificateless cryptography on the client side and Identity-Based Cryptography on the receiver side. The proposed scheme employs Hyperelliptic Curve Cryptography (HECC), a more advanced variation of Elliptic Curve Cryptography (ECC). HECC achieves the same level of security with a smaller key size and a more efficient approach than its counterpart methods. The proposed scheme not only meets the security and privacy standards of WBANs but also enhances efficiency in terms of computation and communication costs, according to the findings of the security and performance analysis.
由于第五代（5G）无线连接的广泛应用，现在可以随时随地提供预防性或主动性医疗保健服务。由于这项技术的改进，近年来无线体域网（WBAN）已经成为医疗保健领域的一个新的研究领域。WBAN 一方面旨在收集和监测人体及其周围环境的数据；另一方面，生物医学设备和传感器通过开放的无线信道进行交互，使它们面临一系列网络威胁。然而，WBAN 是一个异构系统；需要异构加密，其中发射器和接收器可以使用不同类型的公钥加密。本文提出了一种改进的、高效的异构认证方案，该方案具有有条件的隐私保护策略，可在 WBAN 中提供安全通信。在提出的方案中，我们在客户端使用无证书加密，在接收器端使用基于身份的加密。该方案采用超椭圆曲线密码学（HECC），这是椭圆曲线密码学（ECC）的一种更先进的变体。HECC 在使用更小的密钥大小和更有效的方法实现相同安全级别的同时，还提高了计算和通信成本的效率。根据安全性和性能分析的结果，所提出的方案不仅满足 WBAN 的安全性和隐私标准，而且还提高了计算和通信成本的效率。
