摘要:

近些年来,云存储技术得到了高速发展,对云存储的安全也提出了更高的要求；针对目前云存储的数据安全问题,通过对传统加密算法的研究与分析,提出了一种适合云存储的线性AES-ECC混合加密算法；算法综合了AES适应于大块数据加密且加解密速度快而ECC加密强度高的特点,使用交叉加密的方式,极大地提高了云存储的安全性,并从多个角度对算法进行了安全性分析；最后在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,算法在云存储中相比传统加密算法有显著优势。

Abstract:

In recent years, as cloud storage is developing very fast, the higher safety standard is needed. For the confidentiality of the data storage, we analyzed traditional encryption algorithms and proposed a mixed linear AES-ECC encryption algorithm which is suitable for cloud storage.AES is capable of dealing with large files while ECC achieves high efficiency in both encryption and decryption. AES-ECC encryption algorithm combines their advantages together. We analyzed the security of the algorithm from various angles and then we use different algorithms to encrypt and decrypt some types of files on Hadoop platform and compared the encryption and decryption time of the algorithms.The results show that the algorithm has significant advantages over the traditional encryption algorithms in cloud storage.
