Abstract
The emergence of Wireless Body Area Networks (WBAN) provides users with ubiquitous wireless communication services, such as continuous exchange of medical information in real time. Therefore, WBAN is considered to be one of the effective wireless sensor technologies for improving medical services. However, the characteristics of WBAN make it subject to multiple attacks, such as the leakage of private information of users, and WBAN is also inefficient. In this paper, a certificateless ring signature scheme CLRS is proposed. In addition, we propose a public auditing scheme with identity privacy protection, which combines the certificateless ring signature technology for cloud-assisted body area network. Through the analysis of security, it shows that the scheme can resist the existing attack methods such as forging attacks. Finally, the comparison between theoretical analysis and experimental simulation shows that the scheme has obvious efficiency advantages compared with the existing scheme.
Highlights
The body area network (BAN) was first proposed by Zimmerman [1] in 1996, which is called of the wireless body area network (WBAN) because of the use of wireless communication technology
Wireless body area network devices can be divided into wearable devices and implanted devices: wearable devices can be deployed on the human body surface or clothing, and implanted devices can be implanted into the human body
The cloud-assisted body area network is resource–constrained, it is of great significance to propose an efficient and practical public auditing scheme with identity privacy preserving for cloudassisted body area network
Summary
The body area network (BAN) was first proposed by Zimmerman [1] in 1996, which is called of the wireless body area network (WBAN) because of the use of wireless communication technology. In 2013, Wan et al put forward a pervasive health application framework [10] combined with wireless body area network and mobile cloud computing technology, and proposed energy efficient routing strategy, cloud resource allocation and heterogeneous cloudassisted somatic network semantic interoperability and other solutions. The combination of resource constrained body area network with clouds with massive and flexible capacity, it provides more rich digital services for users. How to ensure that cloud servers and auditors provide users with services at the same time and do not disclose patient’s identity privacy has become one of the hot issues in this area. The cloud-assisted body area network is resource–constrained, it is of great significance to propose an efficient and practical public auditing scheme with identity privacy preserving for cloudassisted body area network
