A medical health monitoring network model information processing method and system based on signature aggregation

Abstract

The invention belongs to the technical field of information security, and discloses a medical health monitoring network model information processing method and system based on signature aggregation. The third party authority center provides a pair of public and private keys and a pseudo identity for the user sensor, and stores the real identity and the pseudo identity of the user in a key value pair form; The user sensor encrypts medical information through a public key of the medical server and signs the encrypted information by using a sensor private key; Enabling the aggregator to obtain aseries of information, and performing signature authentication and signature aggregation by the aggregator; The signature aggregation aims to save bandwidth and server storage space; And the medical server decrypts the data after performing the aggregate signature authentication, and provides the medical information of the patient to the medical care personnel. According to the invention, judgmentinformation of health care professionals is transmitted to a real patient through the third-party authority center and the aggregator; A plurality of signatures can be combined into a single aggregated signature through the aggregated signature, so that the bandwidth and the storage cost of the network are greatly reduced.

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
