云存储中的混合加密算法研究

Research of mixed encryption algorithm in cloud storage

针对云存储服务中数据传输和存储过程对数据的保密性、完整性和不可抵赖性等安全需求,根据云存储的特点,结合AES和RSA传统加密算法特性,提出一种具有身份认证的带干扰混合加密算法。从多个角度对算法进行了安全性分析,在Hadoop平台上用不同算法对多种文件类型进行加密、解密实验,并对比其加密解密时间。实验结果表明,该算法在云存储中相比传统加密算法有显著优势。

In cloud storage, to meet the demands of confidentiality, integrity and non-repudiation in the process of data transmission and storage, we proposed a mixed encryption algorithmwith identity authentication and interference on the basis of the characteristics of cloud storage and traditional encryption algorithm of AES and RSA. We analyzed the security of the algorithm from various perspectives. Different algorithms were used to encrypt and decrypt multiple types of files on Hadoop platform and then we compared the encryption and decryption time of the algorithms. The results of the experiments show that the mixed encryption algorithm has significant advantages over the traditional encryption algorithms in cloud storage.
