SURVEY OF SECURITY AND PRIVACY IN WIRELESS BODY AREA NETWORKS FOR HEALTHCARE APPLICATIONS, 2021

Wireless Body Area Network or WBAN is an eyeopener revolution in technological development of E-Health domain that offers the remote mechanism to doctors(or physicians), so they can monitor and collect patient's health related data using wearable sensors. We know that a high degree of system security and privacy plays a major role in protecting this valuable data of patient especially when being used by the health professionals. So, while storage of this data health professionals must have to provide guarantee that the health related data of patient will be kept confidential from intruder or attacker's access. So, it is therefore of great interest to discuss communication architecture and challenges of WBAN. This paper also covers the security and privacy requirements, issues, attacks and then possible solutions for WBANs. At the end, open areas for future research and enhancements are explored.

Wireless Body Area Networks (WBAN) have revolutionized the field of biomedical monitoring and other human centric applications despite many design challenges such as limited available energy and computational resources, requirement of planned deployment for sensing nodes, hardware miniaturization for non (less) invasive sensing and provision of security in WBAN. Complex security mechanisms require more computations and memory read write operations and therefore, cannot be implemented on WBAN nodes. In this paper, we propose a secure and energy efficient framework for WBAN healthcare application against Denial of Sleep (DoS) attacks that target a sensing node's battery by sending useless traffic in network to keep it in active state. The proposed framework incorporates efficient energy utilization, repetitive event detection and controlled (re)transmissions to mitigate DoS attacks. Proposed framework had been compared with Pulsed-MAC protocol in terms of network lifetime at different intensities of DoS attack. Results show that proposed framework increases network lifetime from 16 minutes to 50 minutes under complete DoS attack in comparison to Pulsed MAC. The increase in network lifetime is also significant when less and moderately intense DoS attacks are introduced in WBAN.

Wireless Body Area Networks (WBANs) have gained a lot of research attention in recent years since they offer tremendous benefits for remote health monitoring and continuous, real-time patient care. However, as with any wireless communication, data security in WBANs is a challenging design issue. Since such networks consist of small sensors placed on the human body, they impose resource and computational restrictions, thereby making the use of sophisticated and advanced encryption algorithms infeasible. This calls for the design of algorithms with a robust key generation / management scheme, which are reasonably resource optimal. This paper presents a security suite for WBANs, comprised of IAMKeys, an independent and adaptive key management scheme for improving the security of WBANs, and KEMESIS, a key management scheme for security in inter-sensor communication. The novelty of these schemes lies in the use of a randomly generated key for encrypting each data frame that is generated ...

Body area network (BAN) connects sensors and actuators to the human body in order to collect patient's information and transmitting it to doctors in a confined space with limited users. wireless body area network (WBAN) is derived from wireless sensor networks (WSN) and enables to transfer of the patient's information with a wide range of communication due to the limitations of the wired body area network. It plays a vital role in healthcare monitoring, healthcare systems, medical field, sports field, and multimedia communication. Sensors and actuators lead to high energy consumption due to their tiny size. WBAN facilitates in securely storing patient information and transmitting it to the doctor without data loss at a specific time. This review examines and summarizes methodological approaches in WBAN relating to security, safety, reliability, and the fastest transmission. Flying body area networks (FBAN) utilizing unmanned aerial vehicles for data transmission are recommended to promote rapid and secure communication in WBAN. FBAN improve the security, scalability, and speed in order to transmit patient's information to the doctor due to high mobility.

The wireless body area network has emerged as a new technology for e-healthcare that allows the data of a patient's vital body parameters and movements to be collected by small wearable or implantable sensors and communicated using shortrange wireless communication techniques.WBAN has shown great potential in improving healthcare quality, and thus has found a wide range of applications from ubiquitous health monitoring and computer assisted rehabilitation to emergency medical response systems. The security and privacy protection of the data collected from a WBAN, either while stored inside the WBAN or during their transmission outside of the WBAN, is a major unsolved concern, with challenges coming from stringent resource constraints of WBAN devices, and the high demand for both security/privacy and practicality/usability. In this article we look into two important data security issues: secure and dependable distributed data storage, and fine-grained distributed data access control for sensitive and private patient medical data. We discuss various practical issues that need to be taken into account while fulfilling the security and privacy requirements. Relevant solutions in sensor networks and WBANs are surveyed, and their applicability is analysed. Keywords: Monitoring and Sensing, architecture of wireless sensor network, BAN applications to healthcare promotion.

A Wireless Body Area Network (WBAN) is a collection of low-power and lightweight wireless sensor nodes that are used to monitor the human body functions and the surrounding environment. It supports a number of innovative and interesting applications, including ubiquitous healthcare and Consumer Electronics (CE) applications. Since WBAN nodes are used to collect sensitive (life-critical) information and may operate in hostile environments, they require strict security mechanisms to prevent malicious interaction with the system. In this paper, we first highlight major security requirements and Denial of Service (DoS) attacks in WBAN at Physical, Medium Access Control (MAC), Network, and Transport layers. Then we discuss the IEEE 802.15.4 security framework and identify the security vulnerabilities and major attacks in the context of WBAN. Different types of attacks on the Contention Access Period (CAP) and Contention Free Period (CFP) parts of the superframe are analyzed and discussed. It is observed that a smart attacker can successfully corrupt an increasing number of GTS slots in the CFP period and can considerably affect the Quality of Service (QoS) in WBAN (since most of the data is carried in CFP period). As we increase the number of smart attackers the corrupted GTS slots are eventually increased, which prevents the legitimate nodes to utilize the bandwidth efficiently. This means that the direct adaptation of IEEE 802.15.4 security framework for WBAN is not totally secure for certain WBAN applications. New solutions are required to integrate high level security in WBAN.
