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, which comprises the following steps of: 1, initializing a system, and generating a public parameter,a main key and other entity keys by a trust center; 2, encrypting shared information: a data owner and a cloud computing server jointly encrypting the shared information; 3, generating a user secretkey, wherein a trust center generates the secret key for the user; 4, verifying the integrity of the shared information, and calculating the integrity of the shared information by the cloud computingserver; and 5, decrypting the shared information, and if the shared information is complete, downloading the ciphertext from the cloud storage server by the user and decrypting the ciphertext. According to the method, the operation efficiency and the communication efficiency of the mobile cloud computing data sharing system can be improved, and meanwhile the safety and the privacy in the data sharing process are guaranteed.

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...
