摘　　要：引入可信的第三方TPA,基于RSA算法、Hash函数和DES算法,为云计算提出一种能为数据提供机密性和完整性的安全存储方案SCBRHD。该方案利用RSA算法、Hash函数及DES算法进行加密来确保数据的机密性和存储安全。数据通过二次加密存储在云服务器,加密、解密和认证只涉及终端用户和TPA。给出了方案的架构模型和算法流程,并在Linux平台的Cloudsim云计算仿真环境下对其进行仿真分析,验证其有效性。In this paper, with the introduction of trusted third party TPA（Third Party Auditor）, the SCBRHD scheme is proposed to provide cloud computing with a security data storage of confidentiality and integrity. The scheme uses RSA encryption algorithm, Hash function and DES algorithm to ensure the confidentiality and security of data storage. The data is stored into the cloud server after twice encrypting; the encryption, decryption and authentication only involve the end-user and TPA. The architecture and algorithm of the scheme are also given, and the scheme is simulated in Linux Cloudsim cloud computing environment to verify its validity.
