Embodiment Construction

[0019] The present invention proposes a safe and efficient data sharing method in a mobile cloud computing system, which includes:

[0020] The first step is system initialization, which takes security parameters and attribute space as input through the trust center, and outputs public parameters, master keys, and private keys of data owners, cloud storage servers, and cloud computing servers;

[0021] The second step is the encryption of shared information. This step is jointly implemented by the data owner and the cloud computing server. In order to reduce the communication and computing burden on the mobile terminal, the data owner only performs light operations, including encrypting the plaintext of shared data and Define the access control structure, and operations such as block ciphertext and block label calculation using algebraic signatures are implemented by cloud computing servers;

[0022] The third step is the generation of the user key. Each user who accesses the ...

Abstract

The invention provides a safe and efficient data sharing method in a mobile cloud computing system. In the first step, the system is initialized, and the trust center generates public parameters, master keys and other entity keys; in the second step, the shared information is encrypted, and the data The owner and the cloud computing server jointly encrypt the shared information; the third step is the generation of the user key, and the trust center generates the key for the user; the fourth step is the integrity verification of the shared information, and the cloud computing server calculates the key of the shared information. Integrity; the fifth step is to decrypt the shared information. If the shared information is complete, the user downloads the ciphertext from the cloud storage server and decrypts it. The method can improve the computing efficiency and communication efficiency of the mobile cloud computing data sharing system, and at the same time guarantee the security and privacy in the data sharing process.

Description

technical field [0001] The invention belongs to the technical field of cloud storage security, and relates to a safe and efficient data sharing method in a mobile cloud computing system. Background technique [0002] The popularity of wireless technology and the Internet of Things has led to the rapid development of data sharing in mobile cloud computing systems. Mobile devices such as sensors and mobile phones can be used as nodes for sharing information collection and light processing, while the storage and intensive computing of shared information are realized by cloud servers. . For example, in the mobile cloud electronic medical computing system, patients can upload personal electronic medical information to the cloud through wireless mobile sensing devices and smart terminals for sharing, for medical experts to diagnose diseases or for researchers to dig deeper. To study the distribution and prevention of diseases. Uploading information to the cloud for sharing not o...
