Abstract

The invention discloses a data storage and retrieval method and device, an electronic device and a storage medium. The data storage method comprises the steps of inputting to-be-stored data; encrypting an encryption object in the to-be-stored data according to a data encryption mode indicated by the storage rule to obtain a ciphertext; generating a ciphertext index according to the plaintext keyword of the encryption object and an index generation mode indicated by a storage rule, wherein the ciphertext index is used for retrieving the ciphertext; and storing the corresponding relationship between the ciphertext and the ciphertext index. According to the invention, the method flow of data entry, data encryption storage and ciphertext index creation is completed, the security of data storage is ensured, data leakage and illegal utilization are avoided, and encrypted data can be retrieved through the ciphertext index, so that the data acquisition efficiency of a user is improved. By setting the storage rule, the data storage and retrieval process has good flexibility, safety and high efficiency.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to a data storage and retrieval method, device, electronic equipment and storage medium. Background technique [0002] Cloud storage can provide storage resources as a service to users through the Internet. With the help of virtualization, distributed computing and storage technologies, cloud storage can integrate many storage devices to work together through software to build a cloud platform for external data storage services, which is shared by a large number of users. [0003] However, this cloud storage method has security risks. For example, when user A and user B upload data to the server of the cloud platform, the data of user A and user B may be stored in the same storage device in the cloud platform. In this case, user A and user B share a storage device. If user A’s data is stored in plain text, then user B has the opportunity to use a virtual ...
