云环境下的数据防泄密存储技术
DATA LEAK PREVENTION STORAGE TECHNOLOGY UNDER CLOUD ENVIRONMENT
摘要
Abstract
Preventing data leakage is one of the important directions of cloud storage security research.There are two main ways of data lea-king under the cloud environment:one is the malicious theft of cloud data by cloud services providers,the other is the interception by hackers during the process of plaintext data transmission.In view of this,this paper puts forward a data leak prevention storage technology under the cloud environment.The technology uses fully homomorphism encryption algorithm to encrypt data in advance,which not only enhances the se-curity of data in cloud storage or channel transmission process,but also achieves the direct operation on encrypted data in cloud.In addition, this paper also puts forward key generation algorithm and cipher text retrieval algorithm,they solve the key management difficulty and cipher text retrieval problem caused by this technology.The technology enhances the data confidentiality and improves the cipher text retrieval effi-ciency.关键词
