Abstract: Cloud computing plays a key role towards the world for data sharing. In order to outsource the data in a secure manner the encryption scheme plays an important role in the cloud because sensitive information present in the cloud potentially causes privacy problems. Most of the encryption techniques will split the file in different hunk then the file is encrypted and store on multiple cloud where rather storing complete file on single cloud system. But if any one of the sliced file is corrupted it’s difficult to rearrange the original file format. The proposed KBR agent will store the keys and data with high security in DVM with low budget for the client requirement. The proposed model KBR agent is creating Dynamic Virtual Machines (DVM) based on the Threshold keys and storing those secret keys in the DVMs which perform the high security on keys data and the integrity is maintained by storing the encrypted data in CSP (Cloud Service Provider).
