Embodiment 1

[0167] Embodiment 1 (personal mobile terminal user)

[0168] Such as Figure 7 As shown, Little A lives in a smart community in a smart city, and various smart fields in the smart city (such as smart transportation, smart grid, smart building, etc.) provide him with a convenient and fast smart life. For example: when Little A leaves home, he does not need to manually switch on and off the air conditioner, washing machine, smart rice cooker and other electrical appliances. He only needs to input the corresponding instructions through smart mobile devices (such as mobile phones, iPads, etc.) when going out, and the electrical appliances that need to be turned on and off at home will be Automatic switch; when Little A is driving, he only needs to enter the corresponding command on his mobile device in advance, and the car will automatically adjust the temperature inside the car to an appropriate value a few minutes before he arrives. After getting on the car, Little A You only n...

Embodiment 2

[0170] Embodiment 2 (enterprise)

[0171]At present, smart medical care has entered the lives of ordinary people. Electronic remote diagnosis and treatment systems have sprung up like mushrooms after rain, and various medical websites have emerged in an endless stream. A tertiary hospital realized an intelligent medical system by combining wireless network technology, Internet of Things technology, mobile computing technology, and data fusion technology, which is embodied in: 1) business management system, including hospital charging and drug management system; 2) electronic medical record system, Including patient information and imaging information; 3) Clinical application systems, including computer doctor order entry system (CPOE), etc.; 4) Chronic disease management system; 5) Regional medical information exchange system; 6) Clinical support decision-making system; 7) Public health health system. With the rapid development of the hospital's intelligent medical system, a ...

Abstract

The invention discloses a lightweight and privacy protected public cloud auditing system and method for a smart city. The system includes a smart city, a user, a cloud server (CS) and a third party auditor (TPA). According to the scheme of the invention, the third party auditor (TPA) replaces the user to verify the integrity of outsourced data, and the user does not need to restore a data copy, and the network burden between the user and a cloud storage platform (CSP) is not increased. In consideration of most resource-constrained mobile terminal users and sensor nodes in the smart city, the third party auditor (TPA) in the invention replaces the user to generate a data authentication metadata set, which reduces the computation burden of the user. Secondly, according to the scheme of the invention, the most time-consuming pair operation in the current cryptography can be avoided on the whole, and the cloud storage platform (CSP) no longer needs to blind evidences, the computation overhead of the third party auditor (TPA) and the cloud storage platform (CSP) can be greatly reduced, and the computation burden of the entire cloud storage system can be reduced. The data storage side CSP and the auditing third party TPA are always unable to obtain any information about the data, and thus the privacy of the outsourced storage data can be protected.

Description

technical field [0001] The invention belongs to the technical field of cloud storage data integrity auditing, and relates to a lightweight and privacy-protected public cloud auditing system and method in a smart city. Background technique [0002] As a feasible way to solve urban problems such as traffic congestion, smart home, and smart elderly care, "smart city" has become an inevitable trend of sustainable cities in the future. Smart cities include the following areas of intelligence (such as figure 1 ): Intelligent transportation, intelligent education, intelligent buildings, intelligent economy, etc., they are the basic guarantee for the convenience of residents' lives. In recent years, many European cities have established smart city development strategies. For example, many cities in the UK have successfully transformed into smart cities, solved urban development and reconstruction, revitalized the economy, and promoted satellite navigation, Internet of Things, smart...
