Cloud storage Integrity detection algorithm based on Hashi Shintao Li Cloud storage service enables users to enjoy large capacity and high specification storage services without a large amount of hardware and software input, but it also brings security issues such as data confidentiality, integrity and availability in a cloud environment. Aiming at the integrity problem in cloud storage, a new data integrity detection algorithm based on Hashi structure is proposed by using Hashi structure and large number modulus operation. The analysis results show that the algorithm allows users to detect the end of the remote server data file with high probability and accuracy only in the constant storage, computing and network resources.

Cloud computing storage optimization based on stacked file system Guo Wan Zhangxiaofung The redundancy caused by a large number of virtual mirrors in the cloud environment will result in lower resource utilization and the use of deduplication to ease the need for storage space and network bandwidth, but there are also problems in handling performance degradation. In this paper, a cloud storage optimization scheme based on stacked file system is proposed. The scheme utilizes a scalable file system to store a small amount of modification information of a user to a virtual instance on a read-write disk, storing the virtual image in a reading disk, saving only a small amount of modification information for the virtual instance at a time, without saving ...

Application of data envelope technology in the security of cloud data Pei Huihuiqun cloud computing provides efficient and flexible services at the same time, there are various security risks. Access control methods can improve the security of cloud data and resources, protect users ' privacy, however, traditional access control methods require large security overhead and result in a large amount of data redundancy. This paper optimizes the strategy through the resource segmentation technology, and constructs a secure data envelope for cloud environment with the help of encryption algorithm and viscous strategy. At the same time, the mapping relationship between resources and data envelopes is established, so that users can get the meeting ...

"Ethernet is the backbone of cloud computing. "Is this statement too exaggerated?" Really。 Any data center, cloud computing or anything like that depends on the Ethernet network that allows servers, storage systems, and other devices to transmit to and from each other. No network, no data center. Today, the IT department prepares to deploy an internal cloud environment that can significantly assess how the network infrastructure will affect cloud computing capabilities to meet service level agreements (SLAs). Common terminology to describe cloud computing capabilities, such as agility, flexibility, and scalability, are absolutely applicable to the underlying network and related terms. Considering this point ...

Over the past few years, executives at the corporate level have been hesitant to move data within the data center to the outside because of the inability to guarantee the security and availability of the data that was moved out.
