Data Security And Privacy In Cloud Storage

In recent years, cloud computing technology is developing very fast, making anotherreform in the Internet. At the same time, cloud storage technology is also developing veryrapidly, from only being supplying secondary service for cloud computing service to beinga new independent research field. With more application opportunity in cloud storage, thehigher safety standard is needed. The users hope the cloud storage service provider givesthem more safety insurance so that they can use more cloud storage service.Until now, the research on cloud storage safety still stays initial stage, the papersuggests a new cloud storage safety scheme based on the current information securitytechnology. The scheme is provided by analyzing the cloud storage safety requirement andthe cryptography knowledge and considering the cloud storage characteristic andimproving the current typical cryptography algorithm, especially the attribute-basedencryption algorithm and put it in use, and to be aimed to the integrity verification incloud storage, the paper presents a new quick verification method based on entropy byusing which can accelerate the verification and save system resources, making cloudstorage more effective and useful. Besides, The scheme aim at the other key technology incloud storage, for example, simplifies the SSL protocol to put it in use.All the work makes the designed system more safety and privacy. The theory provedand experimental results show that the scheme can improve the cloud storage system’ssafety and privacy without reducing the system’s efficiency. Of course, the scheme is notgood enough for cloud storage system’s safety and privacy, we want to make it better inthe future’s work.
