基于改进密钥的云计算数据安全存储策略设计
Design of cloud computing data security storage strategy based on improved secret key
摘要
Abstract
As the data size is large in cloud computing environment and the existing data has the dynamic change character⁃istics,the cloud computing data security storage strategy based on the improved secret key is proposed because the traditional se⁃cure storage method obtains the relatively small key space by low dimensional mapping,which may cause low security,is easy to crack,and makes the storage security worse. The general description of tent mapping and cat mapping is given in this paper. It converts the real number domain to the integer domain to make integer arithmetic. The tent mapping and cat mapping are im⁃ported to improve the secret key parameters,and get the primarily⁃iterated secret key. The complementation operation and xor operation for the obtained results are conducted to acquire even encryption cipher byte and verify whether the even encryption is completed,and judge whether the iteration should be finished. In this way,the security storage of cloud computing data is achieved. The experimental results show that the proposed strategy has not only higher safe storage performance,but also needs less time,and does not increase the burden of cloud computing system.关键词
