A Survey on Secure Wireless Body Area Networks

Abstract EN

Combining tiny sensors and wireless communication technology, wireless body area network (WBAN) is one of the most promising fields.

Wearable and implantable sensors are utilized for collecting the physiological data to achieve continuously monitoring of people’s physical conditions.

However, due to the openness of wireless environment and the significance and privacy of people’s physiological data, WBAN is vulnerable to various attacks; thus, strict security mechanisms are required to enable a secure WBAN.

In this article, we mainly focus on a survey on the security issues in WBAN, including securing internal communication in WBAN and securing communication between WBAN and external users.

For each part, we discuss and identify the security goals to be achieved.

Meanwhile, relevant security solutions in existing research on WBAN are presented and their applicability is analyzed.
