An Efficient Dynamic Secret Key in Virtual Machine Using with KBR Agent for Secure File Sharing in Hybrid Cloud

Abstract

Cloud computing performs a key role towards the world for data or file sharing and newlinestoring. In order to secure the data when outsourcing the encryption and decryption newlinescheme plays an major role in the cloud, because the data present in the cloud potentially newlinecauses privacy problems and also a integrity ,performance problem while storing and newlineretrieving the data CSP (Cloud Service Provider). Most of the techniques uses the newlineencryption techniques which will split the file in different hunk then the file is encrypted newlineand store on multiple cloud, where rather storing complete file on single cloud system. But newlineif any one of the sliced file is corrupted it s difficult to rearrange the original file format newlineand also the performance issue and redundant of data will arise. The multiple cloud based newlinestorage will solve many secure and safe storage issues in business. But on the other side newlinemany expert state that it is more risky to put the data over single cloud as it increase the newlineadversary user attack possibilities The proposed model KBR (Key Break and Retrieve) newlineagent is create virtual machines dynamically based on size of the uploading file and the newlinerandom keys generated by LCG then the uploaded file is encrypted along with multiple newlinesecret keys are generated and those secret keys are stored in the VMs which perform the newlinehigh security on keys data and the integrity is maintained by storing the encrypted data in newlineCSP (Cloud Service Provider).comparably the performance are increased while storing and newlineretrieving dynamic secret keys from VMs instead of storing and retrieving from cloud. newline
