Abstract

The invention relates to a system and a method for cloud computing environment data encryption storage and capable of searching. The system for cloud computing environment data encryption storage comprises a key management server, an encryption and decryption server, a user side, a ciphertext indexing server and a cloud platform which are all respectively connected with a key mapping server and exchange data with the key mapping server. Due to the fact that only mapping relation of user identification, key identification and data storage addresses is stored in the key mapping server, only the key identification and key values are stored in the key management server, only ciphertext index containing relative relation of indexing key words and data storage address is stored in the ciphertext indexing server, and only ciphertext data is stored in the cloud platform, so that direct relation between the key values and the ciphertext data which are used in the encryption and decryption server is broken. The key values and the ciphertext data do not exist simultaneously in the position storing the key mapping relation, the key values and the key mapping relation do not exist simultaneously in the position storing the ciphertext data and the key mapping relation and the ciphertext data do not exist simultaneously in the position storing the key values.

Description

technical field [0001] The invention relates to an information security system and method, in particular to a searchable cloud computing environment data encryption 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...
