Abstract
Intelligent networks have developed rapidly in various fields of the world today. As a popular network technology, they have broad application prospects in the fields of telemedicine and health monitoring. The application of this technology has important practical significance for solving many aspects of medical treatment. Aiming at the encryption scheme of fuzzy keyword search and the verifiable problem of the data returned by medical cloud in the security of medical cloud data, this paper analyzes the encryption of medical data outsourcing system on medical cloud and the security search method. A verifiable fuzzy keyword symmetric searchable encryption scheme for medical cloud data outsourcing system is proposed, which not only uses symmetric encryption algorithm, but also supports the search of fuzzy keyword and supports the verification of search results. So that the confidentiality of medical data is guaranteed, medical data administrators in the medical outsourcing data uploaded to the medical cloud server before the medical outsourcing data encryption, when patients or other medical users need to obtain a file, through keyword query to the medical cloud to make a request, so as to ensure that their privacy. It also ensures the integrity and security of the returned results.
Highlights
With the development of network applications in the direction of depth, the network has become the lifeline of the enterprise information system, and the information intelligent network is to optimize the existing network infrastructure, so that the new technology applications such as wireless, storage, and intelligent transmission are added to the existing network conveniently and effectively with the needs of the business
This paper presents a verifiable fuzzy keyword symmetric searchable encryption scheme based on medical cloud data outsourcing system, which uses symmetric encryption algorithm, and supports the search of fuzzy keyword, and supports the verification of search results
6.1 Results analysis In order to ensure the security of medical data, we proposed the above solution and proved the feasibility of our solution through a large amount of simulation data
Summary
With the development of network applications in the direction of depth, the network has become the lifeline of the enterprise information system, and the information intelligent network is to optimize the existing network infrastructure, so that the new technology applications such as wireless, storage, and intelligent transmission are added to the existing network conveniently and effectively with the needs of the business. The medical cloud server is not trusted, but in order to be able to store patient data securely on it, the data must be encrypted before the medical patient’s personal data is outsourced It becomes very difficult for medical data administrators to search for encrypted medical data in a medical server. For the medical cloud, which is widely used, with the rapid development of its sharing and economy, and the medical cloud, but almost all cloud storage systems, like a double-edged sword, where the data stored are mostly related to the privacy of users, if these personal information is leaked, the consequences will affect the lives of these people and even their security, it will be unimaginable. Based on the many keyword searches nowadays, the index structure sk-lsh of Liu
