摘要 为确保数据私密性,用户选择将数据加密后再上传到云端,但云无法为密文数据提供管理和搜索等服务。密文搜索技术可以把保护用户数据私密性和有效利用云服务结合起来。在分析云环境下密文搜索算法的基础上,提出基于云环境的密文搜索体系结构,研究其中的关键技术,指出云环境应用密文搜索技术存在的问题和改进的方向。 In order to ensure the data privacy, users have to encrypt the data before outsourcing them to the cloud, How- ever, the encrypted data cannot take full advantage of the rich service function and powerful computation ability of the cloud platform. Ciphertext search technology can combine the protection of user data＇s privacy with the efficient usage of cloud platform services. On the basis of analyzing the ciphertext search technologies in cloud computing environment, a ciphertext search system architecture based on cloud computing environment was proposed and the key technologies of ciphertext search were studied. Finally the ciphertext search technologies＇ main problems at present and the important re- search direction in future were pointed out.
