Huang Chao · Xinxi wangluo anquan · 2012
Data retrieval method based on homomorphic encryption techniques can be directly on the encrypted data retrieval,not only to ensure the data is not retrieved statistical analysis,to do basic addition and multiplication can be retrieved data without changing the corresponding plaintext the order both to protect the security of user data to improve the retrieval efficiency.This work is proposed to address the problem,a system-level solutions,to solve the problem of secure storage and management of information in the cloud storage system.To achieve this objective,the work uses a homomorphic encryption algorithm,this algorithm on the basis of a cipher text retrieval algorithms,both to ensure the security of user data,but also to ensure the server can store user-ciphertext direct operation,the ciphertext to retrieve the balance of the cloud storage system to ensure the security of user data and services,the relationship between cloud computing.
