Optimized Secure Auditing Protocol for Storage of Data Dynamically in Cloud Computing

Preeti Wadhera | Dr. Rajdev Tiwari ^[3]

Abstract: Cloud computing is growing now days, the one of the most efficient use of cloud is data storage on cloud server. In cloud computing, data owners host their data on cloud servers and users (data consumers) can access the data from cloud servers. Cloud Computing is a type of distributed computing whereby resources and applications are shared over the internet. These applications are stored in one location and can be accessed in different location by any authorized users where the user does not need any infrastructure. But due to the data outsourcing, there are some challenging aspects behind this cloud data storage as per end users perspective, this new paradigm of data hosting service introduces new security challenges, how end users know their data is secure on cloud server How they satisfied that the data is not tampered and successfully updated after performing some operation over it Some existing remote integrity checking methods can only serve for static archive data and, thus, cannot be applied to the auditing service since the data in the cloud can be dynamically updated. Thus, an optimized and secure dynamic auditing protocol is desired to convince data owners that the data are correctly stored in the cloud. Here the Trusted Third Party auditor comes in picture and using auditing framework he satisfy end users that there data is secure over server and successfully updated. So in this paper optimized secure auditing algorithm is designed and also extended to dynamic auditing. We further extend our auditing protocol to support batch auditing for both multiple owners and multiple clouds.
