Merkle Hash Tree with Hash based Digital Signature for Cloud Data Confidentiality and Security

Abstract

It provides efficient processing power, an unbelievable computation speed and a wide array of stage space.Basically, the cloud computing transfer the huge volume of data on the different cloud servers which is maintained by the different kinds of cloud providers and this process help to remove the physical data’s possession even though user are the data owners. This extraordinary element coordinates to raise the innumerable new security disadvantages which have not been surely known obviously. Consequently, in this paper present a novel methodology for secure cloud information stockpiling with the assistance of Merkle Hash Tree (MHT) with hash based advanced mark to give trustworthiness and protection of redistributed information in cloud using private key security approach. Additionally, in this work use theAdvanced Encryption Standard (AES) for conforming the data confidentiality and data security before the data is stored into the cloud. The simulation results show the better results in term of Data Recovery Time, Processing time, and efficiency respectively
