Embodiment 1

[0053] see Figure 1-Figure 4 , this application provides a revocable certificate-free privacy protection authentication scheme in WBANs, including the system initialization phase, the authentication phase between the client and the AP, and the revocation phase, wherein the system mainly includes four participants, They are: network manager (NM), revocation center (RC), WBANs client (C) and application server (AP), where NM is the registration center of AP and C, which is considered to be fully trusted; NM is a function It is to generate system parameters and provide part of C's private key and part of AP's private key. Another function is to add malicious users to the revocation list and notify the RC in the area when malicious users are found; the main function of RC is Update the public key and private key of the area when receiving the revocation notice from NM, and broadcast it; C is a mobile device used to collect biological information such as blood pressure, heart rate...

Abstract

The invention discloses a revocable certificateless condition privacy protection authentication scheme in WBANs, which comprises a system initialization stage, an authentication stage between a client and an AP and a revocation stage; wherein the system initialization stage comprises public parameter generation and user registration, the public parameter generation is used for generating system parameters through an NM, so that data establishment is facilitated; user registration is used for submitting real identity information to facilitate generation and transmission of a public key and a private key, and the authentication stage between the client and the AP comprises identity authentication and establishment of a session key; wherein the identity authentication is used for authenticating whether the identity between the client and the AP is legal or not, and the establishment of the session key is used for enhancing the confidentiality intensity of patient body information; the revocation stage comprises the steps of revealing the real identity of the user and revoking the malicious user. According to the scheme, the validity of the doctor and the patient is ensured, so that the authentication cost is reduced, and the timely efficiency and the calculation efficiency of user revocation are improved.

Description

technical field [0001] This application relates to the technical field of security and privacy protection in modern medical care systems, in particular, it relates to a revocable certificate-free privacy protection authentication scheme in WBANs. Background technique [0002] As part of the modern medical system, with the rapid development of wireless communication, sensor and network technology, the wireless body area network was proposed in 1996 as a part of the medical care system, WBAN is a self-organizing network, which is worn around the body and embedded The low-power medical sensor in the body is formed, which can monitor the patient's biological information such as blood pressure, heart rate and pulse in real time through the sensor, and then send the information to the telemedicine server through the mobile device, and the remote doctor or expert can provide correct information for the patient based on the information. diagnosis and treatment plan. [0003] As the...
