摘要

作为一种特殊的物联网(IoT)应用,无线体域网(WBAN)受到了医疗机构的广泛关注。然而,现有的 WBAN 数据传输方案缺乏无证书密码系统(CLC)和公钥基础设施(PKI)的异构支持,导致密钥托管或复杂的证书管理等问题。此外,由于性能原因,传统的签名加密协议不适合 WBAN 应用。为了弥补这些不足,实现从无线局域网传感器到医院服务器的安全高效的敏感数据传输,我们设计了一种异构在线/离线签名加密方案。我们的方案使病人植入或佩戴的传感器能够在 CLC 中加密敏感数据,并将其发送到 PKI 系统中的医院服务器。CLC 避免了密钥托管问题,而 PKI 则提高了可扩展性。我们将签名加密分为离线和在线两个阶段,将耗时的操作放在离线阶段,从而最大限度地降低了 WBAN 传感器的在线计算成本。此外,我们还正式证明了我们方案的安全性,并对其性能进行了评估。结果表明,我们的方案在支持 CLC 和 PKI 的异构性方面具有优势,而且计算成本较低,因此与现有协议相比,它非常适合在 WBAN 应用中保护数据隐私。

Efficient and secure heterogeneous online/offline signcryption for wireless body area network

As a special Internet of Things (IoT) application, the wireless body area network (WBAN) has gained widespread attention by medical institutions. However, existing schemes for WBAN data transmission lack heterogeneity support across certificateless cryptosystem (CLC) and public key infrastructure (PKI), resulting in issues like key escrow or complicated certificate management. In addition, for performance reasons, conventional signcryption protocols are unsuitable for WBAN applications. To address these gaps and enable secure and efficient sensitive data transmission from WBAN sensors to hospital servers, we design a heterogeneous online/offline signcryption scheme. Our scheme enables patients’ sensors implanted or worn to encrypt sensitive data in CLC and send it to the hospital server in PKI system. The CLC avoids key escrow issue while the PKI increases scalability. We minimize the online computational cost of WBAN sensors by dividing signcryption into offline and online phases, with time-consuming operations in the offline phase. Furthermore, we formally prove the security of our scheme and evaluate its performance. Results show our scheme has advantages in supporting heterogeneity across CLC and PKI with low computational costs, making it uniquely suitable for the protection of data privacy in WBAN applications compared to existing protocols.

期刊介绍: As envisioned by Mark Weiser as early as 1991, pervasive computing systems and services have truly become integral parts of our daily lives. Tremendous developments in a multitude of technologies ranging from personalized and embedded smart devices (e.g., smartphones, sensors, wearables, IoTs, etc.) to ubiquitous connectivity, via a variety of wireless mobile communications and cognitive networking infrastructures, to advanced computing techniques (including edge, fog and cloud) and user-friendly middleware services and platforms have significantly contributed to the unprecedented advances in pervasive and mobile computing. Cutting-edge applications and paradigms have evolved, such as cyber-physical systems and smart environments (e.g., smart city, smart energy, smart transportation, smart healthcare, etc.) that also involve human in the loop through social interactions and participatory and/or mobile crowd sensing, for example. The goal of pervasive computing systems is to improve human experience and quality of life, without explicit awareness of the underlying communications and computing technologies. The Pervasive and Mobile Computing Journal (PMC) is a high-impact, peer-reviewed technical journal that publishes high-quality scientific articles spanning theory and practice, and covering all aspects of pervasive and mobile computing and systems.
