Abstract

The invention relates to a cloud computing environmental data secure storage system and a method. The cloud computing environmental data secure storage system comprises a key management server, an encryption and decryption server, a user terminal and a cloud platform which are respectively connected with a key mapping server and conduct data exchange with the key mapping server. By preserving and maintaining a mapping relation between a key and enciphered data through the key mapping server, a direct relation between a key value and cipher test data is broken. When data memory addresses are sent to the user terminal, or user data are sent to the user terminal, the key mapping server deletes the key value, the user data and the cipher text data; when the encryption and decryption server deletes the key value, the user data and the cipher text data after completing encryption or decryption. The key value and the cipher text data do not exist at the same time in a position which a key mapping relation is preserved, the key value and the key mapping relation do not exist at the same time in a position which the cipher text data are preserved, and the key mapping relation and the cipher text data do not exist at the same time in a position which the key value is preserved, and therefore tripartite independence of the key value, the cipher text data and the key mapping relation is achieved.

Description

technical field [0001] The invention relates to an information security system and method, in particular to a cloud computing environment data security storage system and method. Background technique [0002] Cloud computing is an Internet-oriented distributed computing service. As a delivery model for IT resources and services, it can obtain the required resources from a shared pool of configurable computing resources anytime, anywhere, conveniently, and on demand. (such as networks, servers, storage, applications, services, etc.), these resources can be quickly provisioned and released, while minimizing management costs or service provider intervention. Cloud computing is the most popular technical term in the IT industry in recent years. Many experts believe that cloud computing will change the technical foundation of the Internet and even affect the entire industry structure. At present, almost all IT industry giants in the world are devoted to the research and applicat...
