Embodiment Construction

[0053] The present invention will be further described in detail below with reference to the above drawings. It should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0054] like figure 1 As shown, the wireless medical sensor network mainly includes four entities: medical sensor node (MSN), key generation center (Key Generation Center, KGC), helper (Helper) and medical server (MedicalServer, MS). In the present invention, KGC is responsible for the generation of public parameters, partial private keys and the traceability of malicious medical sensor nodes; MSN is responsible for generating secret values, initial keys, signature keys and generating corresponding signatures; the facilitator is responsible for generating update keys; The medical...

Abstract

The invention relates to a certificateless signature-based strong privacy protection method suitable for a medical scene, which comprises the following steps: step 1), system initialization generation: a key generation center is responsible for generating a system master key and a master public key, constructing a secure hash function and finally disclosing system parameters; step 2), secret value generation: the medical sensor node generates a false identity of the medical sensor node and a part of public key through the randomly selected secret value; the method comprises the following steps of (1) carrying out secret key generation, (2) carrying out secret key generation, (3) carrying out temporary partial private key generation, (4) carrying out initial secret key generation, (5) carrying out updated secret key generation, (6) carrying out signature generation, and (7) carrying out signature verifier.According to the method, a certificateless signature technology is adopted to guarantee safe transmission of medical data, and the method can meet the safety requirements of integrity, authentication, anonymity, traceability and the like of messages.

Description

technical field [0001] The invention relates to a strong privacy protection method based on a certificateless signature suitable for medical scenarios, and a strong privacy protection method based on certificateless signatures suitable for medical scenarios. Scenario in the field of information and communication. Background technique [0002] With the rapid development of wireless communication and the Internet of Things, the emergence of Wireless Medical Sensor Networks (WMSNs) has brought great convenience to human life. In WMSNs, medical sensor nodes on the patient's body can monitor the patient's body data in real time, and transmit the collected medical data to doctors in professional institutions for diagnosis. However, the seemingly complete WMSNs have many security and privacy issues that still need to be resolved. In WMSNs, medical data are communicated in wireless channels, and malicious adversaries can conduct malicious operations such as eavesdropping and tampe...
