摘　　要：针对传统方法在对海量云数据进行存储时无法满足安全需求的问题,提出了一种基于安全性验证的云数据存储与访问算法.该算法将用户传输至云端的数据进行分块重组,同时使用交叉加密方法对不同大小的数据块进行加密,从而实现数据的安全保护与快速加密.当用户申请访问数据时,通过基于安全性验证的访问判断及解密返回用户请求的数据.实验与分析结果表明,所提出的方法能够显著提升云数据存储的安全性并减少数据加密、解密的计算开销,且相比于传统方法,该方法具有更优的存储与访问性能.Aiming at the problem that the traditional methods cannot meet the security requirements by cloud data storage,a cloud data storage and access algorithm based on security verification was proposed.The data transmitted by the user to the cloud were divided and reorganized by the as-proposed algorithm,and a cross-encryption method was used to encrypt data blocks of different sizes to achieve data security protection and fast encryption.When a user applies for access to data,the data requested by the user were returned through the access judgment and decryption based on security verification.Experimental and analytical results show that the as-proposed method can significantly improve the security of cloud data storage and reduce the computational overhead of data encryption and decryption.Compared with traditional methods,the as-proposed method has better storage and access performance.
