A revocable privacy-preserving authentication method without certificate conditions in self-organizing networks

Abstract

This application discloses a revocable certificate-free conditional privacy protection authentication method in an ad hoc network, including the system initialization phase, the authentication phase between the client and the AP, and the revocation phase. The system initialization phase includes public parameter generation and user registration. , the production of public parameters is used to generate system parameters through NM, which facilitates the establishment of data, user registration is used to submit real identity information, which facilitates the generation and transmission of public and private keys, and the authentication phase between the client and AP includes identity authentication And the establishment of session key, identity authentication is used to authenticate whether the identity between the client and AP is legal, the establishment of session key is used to strengthen the confidentiality of the patient's physical information, and the revocation phase includes revealing the user's true identity and revocation malicious user. This solution, by ensuring the legitimacy of doctors and patients, not only reduces the cost of authentication, but also improves the timely and computational efficiency of user revocation.

Description

technical field [0001] This application relates to the technical field of security and privacy protection in modern medical care systems, in particular, to a revocable authentication method for privacy protection without certificate conditions in an ad hoc network. 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 pla...

Problems solved by technology

[0004] The main purpose of this application is to provide a revocable non-certificate conditional privacy protection authentication method in an ad hoc network to improve the existing schemes in the related art. The cost of authentication is high, and the calculation efficiency and revocation efficiency of many schemes are low. The problem of not revoking users from WBAN in time
