Method and system for information processing of medical health monitoring network model based on signature aggregation

Abstract

The invention belongs to the technical field of information security, and discloses a method and system for processing medical and health monitoring network model information based on signature aggregation; a third-party authoritative center provides a pair of public and private keys and a pseudo-identity identification for user sensors, and uses the key-value pair form Save the user's real identity and pseudo identity; the user sensor encrypts medical information through the medical server public key, and uses the sensor private key to sign the encrypted information; makes the aggregator obtain a series of information, and the aggregator performs signature authentication and signature aggregation; Aggregation is designed to save bandwidth and server storage space; the medical server performs data decryption after aggregate signature authentication, and provides patient medical information to healthcare personnel. The invention transmits the judgment information of medical care professionals to real patients through the third-party authoritative center and aggregator; multiple signatures can be combined into a single aggregate signature through the aggregate signature, thereby greatly reducing network bandwidth and storage costs.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a method and system for processing information of a medical health monitoring network model based on signature aggregation. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: uploading medical health monitoring information to medical servers through wireless sensor networks can minimize the need for healthcare professionals. But medical data is vulnerable to numerous attacks such as data interception and data tampering. Although the signature scheme can protect the authenticity and data integrity of data, when the number of users involved in the medical system becomes huge, network bandwidth and server storage costs will become the bottleneck, and the privacy protection of user identity information is also a very serious issue. problem, and existing identity-based signature schemes cannot resist...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing aggregation signature scheme, first of all, cannot resist collusion attacks, and secondly, it cannot realize privacy protection and solve the problem of identity tracking. In the medical field, user privacy protection and information integrity Both accuracy and correctness are particularly important; and in the context of the big data era, the shortage of network bandwidth and other resources also makes single signature, privacy protection and other solutions unable to meet the needs

Existing signature schemes that cannot resist collusion attacks and privacy protection are not suitable for wireless sensor networks
