Protection of wireless technology-enabled e-healthcare data transfer over constrained devices of body sensor networks using lightweight security mechanisms is the demand of health sector nowadays.
A new secure wireless body sensor network architecture (S-WBSN) with reduced CPU cycles and computational cost is proposed. S-WBSN uses OTP-Q (One-Time Pad-Quasi) and Diffie-Hellman key exchange algorithms for encryption and mutual authentication, respectively.
To ensure mutual authentication among <WBSN, Local Processing Center (LPC)> and <WBSN, Data Server> components, the Diffie-Hellman key exchange algorithm is used. Using the S-WBSN architecture, security requirements such as mutual authentication, and privacy preservation thwarting security attacks are perfectly met comparing other security-based research works on healthcare data monitoring.
The one-time pad-based quasi-group algorithm is a stream block cipher that operates on the data observed from the sensors of the WBSN. Before transmitting encrypted data, authentication is to be established.
The proposed system methodology proves to be efficient and consumes fewer CPU cycles. The encryption and decryption processing times are comparatively less than the state-of-the-art approaches.
保护无线技术支持的电子医疗保健数据在身体传感器网络的受限设备上传输，使用轻量级安全机制是当今卫生部门的需求。
提出了一种新的安全无线体传感器网络架构（S-WBSN），具有降低的 CPU 周期和计算成本。S-WBSN 使用 OTP-Q（一次性密码本准）和 Diffie-Hellman 密钥交换算法分别进行加密和相互认证。
为了确保<WBSN、本地处理中心（LPC）>和<WBSN、数据服务器>组件之间的相互认证，使用 Diffie-Hellman 密钥交换算法。使用 S-WBSN 架构，可以满足安全要求，如相互认证和隐私保护，防止安全攻击，与其他基于安全的医疗保健数据监测研究工作相比。
基于一次性密码本的准群算法是一种流块密码，它对 WBSN 传感器观测到的数据进行操作。在传输加密数据之前，需要建立身份验证。
所提出的系统方法被证明是有效的，并且消耗更少的 CPU 周期。加密和解密处理时间比最先进的方法要少。
