Problems solved by technology

[0002] In the current cloud computing market, cloud computing service providers such as Alibaba Cloud, Google Cloud, Microsoft Cloud, and Amazon Cloud provide data owners with cloud storage and computing services on the cloud platform, which helps data owners to solve Solving the storage and management problems of these massive data materials can save the local storage space and management costs of the data owners. However, how to process and calculate user data under the premise of protecting data privacy can help data owners truly Capturing the intrinsic value of the desired data, such as correlation, causation, etc., is a problem that has not been fully solved so far
Although the popularity of cloud computing online computing services has solved the problem of data computing, it has challenged the protection of user data security and privacy.

Abstract

The invention provides a data security protection method and device based on cloud computing. The method comprises the following steps of calling a key generation function, inputting security parameters and outputting an encryption and decryption key pair; sharing an encryption key in the encryption and decryption key pair to a data master terminal; negotiating with the data master terminal to determine a maximum value of the number of data entries in order to make the data master terminal form ciphertext data according to the encryption key and the maximum value of the number of data entries,and uploading the ciphertext data to a cloud server for storage; and receiving encryption data information sent by the cloud server and / or a proxy server, and decrypting according to a decryption keyin the encryption and decryption key pair. According to the technical scheme, the local storage space and the data management cost of the data master terminal are saved, and meanwhile, the faster andmore accurate computing capability is obtained by utilizing the functions of the cloud computing, and the privacy of user data and the privacy of related computing requests are effectively protected.
