Abstract Cloud computing is one the promising and emerging field in Information Technology because of its performance, low cost and great availability. Cloud computing basically gives services to an individual and the organization through the network with the capability to scale down or up their different kinds of services. The basic service of cloud computing system is known as a cloud storage system which containing a collection of storage servers.

These storage servers gives long-term storage services by using the internet with free of cost. However, the storing data using cloud system of third party causes very serious problem over data confidentiality. Typically, different kinds of encryption schemes are used to protect the cloud data confidentiality, but it take more time to process even a single operation. Thus, in this paper proposes cloud data confidentiality by integrates encoding, encrypting and forwarding. Token Based Data Security Algorithm (TBDSA) along with RSA and AES is used for decryption and encryption process and Role Based Access Control Model (RBACM) is access at the time of data forwarding.

Here, cloud user’s accessing password is created by using encoding process which is done by Genetic Algorithm (GA) and process of GA is presented in this paper. This

1. Introduction The cloud is a term which is utilized for a virtual collection of resources and it has wide range of advantages. These advantages are offered for cloud users to utilize the availability of vast array of software applications, looking unlimited storage, to access the lightning fast power of processing and the ability to effortlessly share information across the world [1]. Cloud users access all of these advantages over the internet at any place and any time. Cloud computing is also allows corporate and consumers structure to utilize all the cloud application without added any extra effort for hardware and software installation. Additionally, it offers personal files sharing process from any computer over the internet access [2].

International e-Journal For Technology And Research-2017 Cloud computing becomes a complex infrastructure because of their hardware, software, storage and processing and which are available in the form of service [3]. The cloud services are included basically of application running remotely which is made data available to all the cloud users.This kind of technology offers access to a huge volume of advanced super computers and connected at many locations around globally, thus offering speed is tens of trillions of computations per second.

Initially the setup a hybrid cloud in the process, the administrator is known as main authority and the authority creates the cloud user’s username and password for and generates the secret key for role corresponding role manager, here have to define the role hierarchy. Manage the given user name and password by using role manager and the owner is the cloud user who has the authority to store or upload the cloud data securely in the cloud system. The users want to decrypt to access the stored cloud data. The proposed cloud storage and accessing system is as shown in figure 1.

In this integration may overcome the each other disadvantages. The private cloud will not be exists from the user, so the user only interact with the public cloud over the administrator. The administrator will be permit to access the private cloud.

Administrator: The main authority of secure cloud storage system is termed as administrator and the administrator has all the credentials and system parameters to manage the secure cloud.

Additionally, the administrator adds cloud users and role manager in the framework and provides fundamental credentials to access the secure cloud system. The

Role Manager: A role manager is used to manage the relationship between specific roles and cloud users. When updating the user roles, the role manager required to enter the password given by the administrator. No one of the cloud users are affected by this operation, therefore the role managers do not required to communicate with the cloud users, and they only required to interact with private cloud. Beforehand a user is involvedinto a given role and the role manager required authenticating the cloud user so as to ensure that the user is authorized user.

Owner:

It faces the main problem because of key exchange. To overcome this issue, in this work use RSA algorithm for generating encrypted secret key with the help of user’s public key.

3.1 Data Storage In this proposed work Role Based Access Control Model (RBACM) is proposed. Thus, the roles manager assigns the each role to the cloud user who can work with their appropriate role. The cloud provider is not able to find the data which is stored in the form of encrypted data. A role manager is able to allocate a role for specific user after the data owner has encrypted the data. A user allocated to specific role can be revoked at any time, the revoked user have not any access permission to data. The user revocation will not affect other cloud users. This work, achieves a great encryption and decryption process on client side.

In this, initially required to create the cloud user, allocate the specific roles to the user and this process comprises IDL - International Digital Library

subsequent operation. In the proposed work Advanced Encryption Standard (AES) [10] [11] algorithm utilized for encrypt the cloud data and the secret key generated by AES is encrypted by using Rivest-Shamir-Adleman(RSA) algorithm [12]. When the roles in the proposed framework defined then the each and every roles have one private key and public key.

The private key is utilized by the cloud user to access the cloud data from different cloud server. The public key is utilized by the cloud data owner to encrypt and upload or store the cloud data in public cloud.

Basically, the AES algorithm initiated with Add round key stage than it will followed by nine rounds of four different stages and a 10th round of three different stages. Here, the four different stages are defined as Substitute bytes, Mix Columns,Shift rows, and Add Round Key. AES working process is as shown in figure 2. Initially, the nine rounds of AES decryption process contain Inverse Substitute bytes,Inverse Shift rows,Inverse Mix Columns andInverse Add Round Key. Again the 10th round not executesthe Inverse Mix Columns stage as same as 9th round as shown in figure 2.

Thus, the security level of cloud storage is very high and data recovery is also secured by using obtaining OTP. As the architecture of proposed system shows cloud security utilizing OTP by using GA in figure 1. Initially Admin upload the data on cloud so that each and every register cloud user can access the cloud data with using their specific role. For accessing data user required to do two important processes such as user registration and submission of OTP. From the architecture registered user want to access the cloud data, the user must be logged in. After login the user gets their OTP on mail or mobile and when user gets the OTP they should enter in the system correctly. If OTP correct the system will permit for data accessing otherwise the system will ask correct OTP. The data recovery using GA is as shown in Figure 4.
