摘要 将密文规则的基于属性加密技术同Lucene全文索引技术相结合,提出适合云存储中密文数据全文检索的方法;针对云存储的特点改进了密文规则的基于属性加密技术.给出了设置在企业端的私有安全模型,并基于Lucene全文索引引擎以及改进的密文规则的基于属性加密方案开发设计了密文全文检索服务和数据加密与访问控制服务.在Eucalyptus云平台上实现了该安全模型的主要服务模块.该安全模型较好地解决了企业数据云存储的机密性与密文全文检索问题. Based on ciphertext-policy attribute-based encryption and full text indexing technology of Lucene, a method of ciphertext data in full text indexing and retrieving is proposed for cloud storage applications. An improved ciphertext-policy attribute-based en- cryption is presented according to features of cloud storage applications. A security model deployed in enterprise sides is proposed. Services of data encryption, ciphertext fulltext retrieval and access control are designed based on Lucene full text indexing engine and the improved ciphertext-policy attribute-based encrypfion. The security model can be used to solve the problem of data confidential and ciphertext full text retrieval of an enterprise in the cloud storage properly.
