Abstract

The invention discloses a method for Key-Value database encryption and security query in shared cloud. The method comprises the steps that a Key-Value database security protection model based on multilevel self-description is adopted to customize a data security protection scheme, and encryption processing and query processing are performed on a Key-Value database according to the security protection scheme through a security agent secure KeyValue. The method is suitable for all Key-Value databases, and the confidentiality and integrity of user data in a shared cloud environment can be well protected.

Description

technical field [0001] The invention belongs to the field of computer software, and in particular relates to a method for encryption and safe query of a Key-Value database in a shared cloud. Background technique [0002] Data analysis, enterprise, multimedia applications, and many applications in scientific research including genomics, structural biology, astronomy, meteorology, engineering, and economics utilize cloud computing to process massive data sets. Big data and mobile applications are two of the most important growth areas in cloud computing. Many of the cloud services they use must operate under strict latency constraints, and in addition, these cloud services must handle massive data volumes while simultaneously providing reliable services to very large user groups. Traditional relational databases can no longer meet the processing of massive data and the real-time requirements of online applications. NoSQL databases have the characteristics of flexible storage ...
