Recently, with the technical advancements in wearable medical sensors and wireless communication techniques, Wireless Body Area Network (WBAN) has emerged as a new technology for e-health care service. The wearable medical device (WMD) aims at collecting an individual's medical data unobtrusively and ubiquitously. The security of the data collected from a WBAN remains a major unsolved concern. So, a certificateless remote anonymous authentication protocol is used to overcome the above challenges and to prevent the leakage of user's private information from unauthorized users. It eliminates the need for distributing clients account information to the application providers and also it achieves forward security. However the revocation functionality of anonymous remote authentication for the WBANs has not been considered in case the private key of the user has been leaked or the misbehaviour of the user has been detected. To address the demand a certificateless remote authentication protocol with efficient revocation is proposed. KUNodes algorithm is used to achieve the efficient revocation function. The revocation mechanism is highly scalable and it is especially suitable for the large-scale WBANs. The proposed authentication protocol is computationally efficient and it is provably secure against existential forgery compared with the existing one. Several key applications ranging from remote health monitoring to military/fitness training can be enabled by remote authentication in WBANs.
Secure and Efficient Certificateless Signcryption Protocol for Wireless Body Area Networks (WBANs)
In WBANs, security and efficiency are critical concerns. Devices communicate via an insecure short-range communication standard, exposing patients’ sensitive data to security breaches. Additionally, WBAN entities are resource-constrained devices that demand lightweight computations. Meanwhile, researchers have designed numerous schemes to combat the abovementioned problems. Nevertheless, several schemes rely on bilinear pairing and certificate management, which are heavy cryptographic operations, thus suffering computational inefficiencies. To resolve security and efficiency issues, we design and validate a secure and efficient certificateless signcryption scheme using elliptic curve cryptography and general hash functions to signcrypt and unsigncrypt messages. Besides, we conduct formal security proof using the Random Oracle Model (ROM) to demonstrate Indistinguishability under Chosen Ciphertext Attack (IND-CCA) and Existential Unforgeability under Chosen Message Attack (EUF-CMA). From the formal security proof, the proposed scheme has proven to be IND-CCA and EUFCMA secure against adversaries of Type I and Type II. Finally, we conduct efficiency evaluation in terms of computation and communication costs. During performance evaluation, we analyzed the computational and communication costs and compared them with state-of-the-art works, where the proposed scheme showed computation efficiency improvements and communication efficiency improvement against other schemes. Compared to existing schemes, the scheme from this study has better performance in terms of computation and communication cost, thus its applicability in WBANs environment.
Provably secure certificateless protocol for wireless body area network
Wireless Networks
Wireless body area networks are gaining popularity due to their innovative applications such as timely analysis, remote monitoring of patients' health, and high patient care quality. However, these healthcare systems that carry patient's physiological data need special attention for the security and privacy of information. Due to the openness of transmitted data, the healthcare system gets prone to several adverse attacks. In this paper, a provably secure remote healthcare system is proposed based on the elliptic curve cryptosystem. The goal is to enable confidentiality and privacy of sensitive information by designing a certificateless authenticated key agreement protocol with low computational cost and higher security. The proposed scheme achieves anonymity, resistance to key escrow problems, mutual authentication between the sensor nodes attached to patients and the application provider. Furthermore, the protocol undergoes formal security analysis using the random oracle model, and the soundness of the proposed scheme is validated using ProVerif. Finally, the performance analysis depicts that the proposed scheme is efficient compared to existing methods.
Efficient Certificateless Access Control for Wireless Body Area Networks
— Wireless body area networks (WBANs) are expected to act as an important role in monitoring the health information and creating a highly reliable ubiquitous healthcare system. Since the data collected by the WBANs are used to diagnose and treat, only authorized users can access these data. Therefore, it is important to design an access control scheme that can authorize, authenticate, and revoke a user to access the WBANs. In this paper, we first give an efficient certificateless signcryption scheme and then design an access control scheme for the WBANs using the given signcryption. Our scheme achieves confidentiality, integrity, authentication, non-repudiation, public verifiability, and ciphertext authenticity. Compared with existing three access control schemes using signcryption, our scheme has the least computational cost and energy consumption for the controller. In addition, our scheme has neither key escrow nor public key certificates, since it is based on certificateless cryptography.

In the last few years, the wireless body area network (WBAN) has emerged as an appealing and viable option in the e-health application domain. WBAN technology is primarily used to offer continuous screening of health data to patients, independent of their location, time, or activity. A WBAN, on the other hand, is vulnerable to different cyberattacks due to the openness of the wireless environment and the privacy of people’s physiological data. A highly efficient and secure cryptographic scheme that can fulfill the needs of resource-constrained WBAN sensors and devices is considered necessary. First, we take a look at the most up-to-date security solutions for WBANs. Then, we go through some of the underlying concerns and challenges with WBAN security. We propose a new framework called secure channel free certificateless signcryption scheme for WBANs based on a hyperelliptic curve that can meet security requirements such as confidentiality, anonymity, integrity, resistance against un...

Secure Techniques for Channel Encryption in Wireless Body Area Network without the Certificate
Wireless Communications and Mobile Computing, 2022
Wireless body area networks (WBANs) have seen an increase in popularity in recent years. Electromagnetic waves created by the body have the capacity to connect nodes all over the epidermis and throughout the body. If the gadget does not cause discomfort or harm, it can be linked to or implanted in the body. This is something that is currently being worked on. Other factors influence an individual's genuine mobility and the ease with which they can use something. Participating in social networks may enhance the lives of members. WBANs equipped with sensors can monitor a user's heart rate and communicate that information to the user's physician. WBAN has been shown to be a dependable electronic health solution. WBAN technology allows you to follow your patient's data no matter where they are, when they are, or what they are doing. However, because it runs in an open Wi-Fi environment and can conceal users' physiological data, it is more vulnerable to assault. To deal with resource-constrained WBAN sensors and devices, a cryptographic solution that is both very efficient and extremely secure is required. Our primary priority will be the safeguarding of the WBAN network. WBAN contains several significant security weaknesses that must be addressed immediately. WBANs might benefit from certificateless signature encryption that uses a hyperelliptic curve and works over a secure channel. We are outpaced by the opposition by 4.58 milliseconds.
