Unattended Wireless Sensor Networks (U-WSNs) use a non-stationary objects so-called sink node (SN) or mobile sink (MS) to perform a few data computation processes including collection and analysis. This network has a wide range of medical applications to exploit the key features of primary sensing units associated with their computing devices such as blood pressure, pulse oximeter and insulin pump to play a crucial role in stimulating the monitoring systems remotely (hostile environment). In traditional WSNs, the sensing units report the observed data to SN/MS via dedicated network, whereas in U-WSNs, the sensing units gather and keep the observed data in their local cache. At a later time, SN/MS accesses the network throughout the time interval to recover the observed data from the local cache. To fulfill the potential features of SN/MS, the emerging technologies practiced in healthcare applications use fundamental features of the Internet of Things (IoT). Despite the fact of being more accessible and potentially in service, security is highly concerned in restraining the unsatisfied threats in 5G infrastructure. Thus, in this paper, a lightweight two-factor authentication with anonymous data access framework is proposed (L2FA-ADA) using SN/MS. To examine the key properties of cryptographic protocols, the appropriate key agreement schemes were extensively researched. Moreover, the proposed L2FA-ADA utilizes a strategy of two-factor authentication with anonymous data access to ensure perfect forward secrecy with a significant degree of security efficiency. The security analysis including formal and informal shows that the proposed L2FA-ADA is provably protected in securing data privacy, integrity, and confidentiality. In conclusion, using a practical testbed, the key metrics such as transmission efficiency and overhead ratio were evaluated to signify the performance efficiencies of the proposed L2FA-ADA compared to other relevant state-of-the-art approaches.
