Problems solved by technology

Traditional medical cloud storage is inappropriate to generate trusted authentication queries on medical public clouds or on the client side, because none of them can guarantee to provide fair authentication results
For third-party authentication, users of local medical institutions are not the only ones who can obtain public medical data in the medical public cloud. Users of telemedicine institutions and users of medical institutions will also obtain the public medical data due to actual needs. A safe and effective solution for users of medical institutions to obtain data

Abstract

The invention provides a cloud computing public cloud file storage and retrieval method; the method comprises the following steps that a local medical institution terminal generates an encryption private key; the encryption private key is used for encrypting a public cloud file block and then storing encrypted data to a public cloud; the local medical institution terminal sends a request for obtaining the data and the distribution number t of the encryption private key to the public cloud; the public cloud is used for decrypting the data by using the encryption private key and then returning the decrypted data to the local medical institution terminal, meanwhile, the distribution number t of the encryption private key is stored; and after the identity of a remote mechanism terminal is confirmed, an encryption authentication request flag tagc is obtained according to the distribution number t of the encryption private key and returned to the remote mechanism terminal. According to the cloud computing public cloud file storage and retrieval method provided by the invention, the effective information of a medical data storage system can be effectively prevented from being acquired bymalicious attackers; the reliability of the medical data storage system is greatly enhanced; and the fault tolerance rate and the calculation strength of the system are reduced in the data recovery process.

Description

technical field [0001] The invention relates to secure cloud computing, in particular to a method for storing and retrieving files in a cloud computing public cloud. Background technique [0002] Trusted cloud computing is a trusted cloud computing platform supported by hardware security modules that is widely used in computing and communication systems. Trusted cloud computing is born for behavioral security. The core concept of trusted cloud computing is the key. The security of the key in the persistence of medical data is the basic guarantee of the entire trusted medical data storage system. It is inappropriate to generate trusted authentication queries on the medical public cloud or on the client side of the traditional medical cloud storage, because neither of them can guarantee to provide fair authentication results. For third-party authentication, users of local medical institutions are not the only ones who can obtain public medical data in the medical public cloud...
