Abstract
Internet integrated sensor networks have gained much importance and exponential growth in wireless body area networks (WBAN) over the last few years. These networks are used in health services to remotely monitor the health of patients and send/receive sensitive, time critical medical data. Because of the wireless and broadcast nature of WBAN, it is easy for an adversary to get, inject, or update the information transmitted in the medium or launch many security attacks. To protect the sensitive data of the patient, we propose a secure communication strategy for different sensors to form a WBAN. Here, a new node ID is assigned for sensors by using public key cryptography to communicate in the network. An energy utilization and communication cost analysis show that our approach incurs less communication overhead as compared with the recently proposed secure solutions in WBAN. The complexity analysis show that the proposed model works efficiently for secure communication in WBAN.
Highlights
The sensor network continuously provide services to various life changing application such as healthcare, agriculture, nuclear power plant monitoring, water monitoring, air pollution monitoring, weather prediction monitoring and earth sensing monitoring
Body Area Networks (WBAN) having sensors attached with the human body and an environment and forming wireless body area networks (WBAN) have sensing, transmitting and processing capabilities and are integrated with Internet for immediate and fast healthcare services [3]
After that NH generates a token by including unique ID of NS public key of new node (PUS), ID of the known node (IDS), ID of the NH (IDH) and the timestamp value
Summary
The sensor network continuously provide services to various life changing application such as healthcare, agriculture, nuclear power plant monitoring, water monitoring, air pollution monitoring, weather prediction monitoring and earth sensing monitoring. Various types of data such as electronic medical records, patient identification, biomedical information, patient accounts and doctor prescriptions are present. These records must be confidential and generated from an authenticated source. The healthcare services through internet can offer various facility for patient and medical service providers It can invite many attackers and malicious activities to harm the healthcare networks. This data analysis suggest that organizations must take back up of their data and keep identifying internal threats [11].
