With the development of Internet technology, wireless body area network technology is proposed to improve people’s scientific and technological information level in this environment. Since the information collected and processed by wireless body area network is the privacy data of users, security and privacy are the focus of wireless body area network research. In this paper, a scheme to establish a variable radius mixing region is proposed. This scheme obtains the combined communication range by analyzing the user privacy conditions after the hybrid zone is established. According to the different conditions of users, a variable radius dynamic hybrid zone was established to maximize benefits. After the establishment of the hybrid zone is initiated, the members in the zone use the temporary symmetric secret key obtained from the unit for encrypted communication to ensure the demand for real-time message transmission. And finally an anonymous change protocol is proposed. The experimental data prove the feasibility of the renaming scheme of the mixed zone. Compared with other methods, the computation and traffic of this protocol are increased by 7% and 9 % respectively. The validation efficiency of batch validation algorithm is 93 %. The scheme in this paper is more flexible than the establishment of other fixed mixed zones, and the accuracy of this scheme is more accurate than the establishment of general dynamic mixed zones. Finally, it is proved that this scheme not only meets the conditional privacy policy but also uses the model to establish a dynamic hybrid area, which has more accurate accuracy and lower computational consumption, and plays an important role in the security protection of network privacy.
