云存储安全交叉加密算法研究

Research on Cloud Storage Security Cross Encryption Algorithm

云存储服务是云计算领域最基本的服务,具备较大发展潜力,近年来成为研究热门。由于云存储安全技术是一些现有技术综合体,数据可能出现泄露,导致用户对数据存储安全产生担忧。以提高云存储安全加密算法性能为目的,通过对传统安全加密算法的研究及优缺点分析,针对其缺点进行优化改进,以对称加密算法DES和非对称加密算法RSA为基础,充分发挥传统加密算法优势,提出一种更加安全高效的交叉加密算法。在Hadoop平台上对不同类型文件进行加解密实验,并与传统安全加密算法进行对比,结果表明,该算法更加安全高效。

Cloud storage service is the most basic service in the field of cloud computing, which has great potential for develop ment and has become increasingly hot in recent years. Cloud storage security technology is a combination of existing technologies so that there exists possibilities of data leakage and there are many concerns about usersr data storage security. It is hoped to improve the performance of cloud storage security encryption algorithm through the study of the traditional security encryption algorithm and analysis of its advantages and disadvantages. Aiming at its shortcomings, we propose a more secure and efficient cross-encryption algorithm based on symmetric encryption algorithm DES and asymmetric encryption algorithm RSA, which gives full play to the advantages of these two traditional encryption algorithms. At last,the performance of this algorithm is veri fled on Hadoop platform. With this method, different types of files are decrypted and compared with the traditional secure en cryption algorithm. The results show that this algorithm is more secure and efficient.
