Anonymous identity authentication method for patient and doctor under wireless body area network

Abstract

The invention provides an anonymous identity authentication method for a patient and a doctor under a wireless body area network, which comprises the following steps: a registration center initializes the wireless body area network; the doctor and the patient of the wireless body area network register; the doctor communicates with the registration center, and the registration center generates a digital license for the doctor and presets the digital license to an intelligent card; the registration center writes the master key and the public key into the handheld terminal of the patient; a doctor logs in the wireless body area network to generate query information, a message is generated by using the smart card and sent to the patient, and the patient verifies the legality of the doctor by using bilinear mapping and then sends the legality to the doctor; and the patient generates a message and sends the message to the doctor, and the doctor receives the physiological data after verifying the legality of the patient through bilinear mapping after receiving the message. According to the invention, the doctor and the patient are ensured to complete identity authentication in an anonymous manner in the WBAN environment, the identity privacy of the patient and the doctor is protected, and effective transmission of data is realized; and doctor identity tracing is introduced, so that the real identity of the doctor can be traced.

Description

technical field [0001] The present invention relates to the technical field of wireless network applications, in particular to a method for anonymous identity authentication of patients and doctors under wireless body area networks, which realizes anonymous authentication of patients and doctors based on elliptic curve encryption algorithm, and pairs patients and doctors based on bilinear Perform authentication, encrypt authentication messages based on the elliptic curve encryption algorithm, and protect identity privacy by using time stamps. Background technique [0002] In recent years, with the widespread use of mobile devices, sensors and wireless sensor networks, and the continuous development of the Internet of Things (IoT), a new type of network that is embedded or worn on the body has emerged—Wireless Body Area Network. (Wireless Body Area Networks, WBAN). WBAN consists of several small-sized, low-power implantable and wearable sensors, which are used to monitor som...
