A cloud data integrity verification algorithm based on homomorphic hash function

Cloud data integrity verification algorithm based on homomorphic hash function Zhou Rui Wang Cloud storage has become a trend for future storage development, but it also poses new security challenges, such as the possibility that cloud service providers might tamper with data for some reason. To ensure the integrity of cloud data, a cloud data integrity checking algorithm based on homomorphic hash function is proposed. Under the audit of trusted third party, the algorithm verifies the integrity of cloud data by aggregating multiple RSA signatures. In order not to disclose user data information, the same-state linear authentication and random masking technology are adopted to realize privacy protection. The analysis results show that the algorithm can not only ...

Analysis: Data integrity monitoring techniques in cloud storage

Cloud storage is a very attractive service for outsourcing day-to-day data management, but once data is lost, all the consequences will be borne by the company that owns the data, not by the hosting service provider.     With this in mind, it is important to understand the reasons for the loss of data, how much responsibility the cloud service provider is responsible for, how to secure the use of cloud storage, and the integrity monitoring methods and standards regardless of whether the data is stored locally or in the cloud. Integrity monitoring is essential to cloud storage services, as well as data integrity ...

The five strategies of using MAPREDUCE+HDFS and mass data to weigh heavily

With the rapid growth of the amount of storage data, more and more people begin to pay attention to the method of reducing storage data. Data compression, single-instance storage, and duplicate data deletion are frequently used storage data reduction techniques. Duplicate data deletion often refers to the elimination of redundant child files. Unlike compression, duplicate data deletion does not change the data itself, but eliminates the storage capacity that the same data occupies. Data de-duplication has a significant advantage in reducing storage and reducing network bandwidth, and is useful for scalability. As a simple example: in the special for telecommunications operations agreed to the call details to apply ...
