云存储环境下的数据防泄露保护方案
Scheme for data leakage protection in cloud storage environment
摘要
Abstract
To solve the problems of data leakage protection in cloud storage environment,this paper proposed a suitable scheme.This scheme could control the production process of the cipher text by using users’attribute value as encryption pa-rameter.Only users with specific attributes could search for keywords through their own private keys.This scheme made it pos-sible to control users’access scope according to different attribute values,so as to achieve the purpose of fine-grained access control.The scheme has good flexibility and applicability when decrypting party is not fixed.The function test verifies feasibi-lity of this scheme,and the performance test shows the proposed scheme is more efficient than other traditional schemes.关键词
