Cloud computing is the revolution through which individuals can share resources, services and data among the users through the network. Since millions of users uses the same network for data transfer, the data becomes more vulnerable to different security attacks from intruders. Providing security to these data has become the critical area of concern. The current system for data security concentrates on providing security to the stored data in cloud storage but concerns less on securing the data while it is being transferred. The data becomes prone to intruder attacks while being transferred. Also, in the current existing trend, the third party auditor is given access to data during data transfer. This also increases the access vulnerability of data as the intruder could act as third party and gain access to the data. Considering security as a crucial issue, the system proposed concentrates on providing security to transferring data using encryption technique. The system also takes into consideration the issue concerned with the third party auditor, that in the proposed approach, the auditor is denied access to the user data. Experiments are conducted and has shown that the proposed approach increases the overall security of system by making it difficult for intruders to crack the data being transferred.

Enhanced cloud data security using AES algorithm

Cloud computing is based on network and computer applications. In cloud data sharing is an important activity. Small, medium, and big organization are use cloud to store their data in minimum rental cost. In present cloud proof their importance in term of resource and network sharing, application sharing and data storage utility. Hence, most of customers want to use cloud facilities and services. So the security is most essential part of customer's point of view as well as vendors. There are several issues that need to be attention with respect to service of data, security or privacy of data and management of data. The security of stored data and information is one of the most crucial problem in cloud computing. Using good protection techniques of access control we can resolved many security problems. Accept that managing privacy and security of information in web highly challenging. This paper describes how to secure data and information in cloud environment in time of data sharing or storing by using our proposed cryptography and steganography technique.

Three step data security model for cloud computing based on RSA and steganography

Cloud computing is an Internet-based computing and next stage in evolution of the internet. It has received significant attention in recent years but security issue is one of the major inhibitor in decreasing the growth of cloud computing. It essentially shifts the user data and application software to large datacenters i.e, cloud, which is remotely located, at which user does not have any control and the management of data may not be completely secure. However, this sole feature of the cloud computing introduce many security challenges which need to be resolved and understood clearly. One of the most important and leading is security issue that needs to be addressed. Data Security concerns arising because both user data and program are located in provider premises. In this study, an attempt is made to review the research in this field. The results of review are categorized on the basis of type of approach and the type of validation used to validate the approach.

A Review on Data Security in Cloud Computing

The security of cloud computing has always been an important aspect of quality of service from cloud service providers. However, cloud computing poses many new security challenges which have not been well investigated. This paper focusing on issues relating to the cloud data storage methods and security in virtual environment. We propose a method for providing data storage and security in cloud using public key cryptosystem RSA. Further, describes the security services includes key generation, encryption and decryption in virtual environment.

Data security in cloud using RSA

Cloud computing is a system that allows data to be saved in the cloud on a virtual worker. Outsiders and virtual machines in the cloud worker supplier played a critical part in efficiently storing and accessing information. Security, access control, and load balancing are critical challenges in cloud engineering. In the past, various solutions for adjusting cloud load have been proposed. Operator-based burden adjustment calculation surpassed all other offered CPU use, cost, and idle time strategies. The productivity of the specialist-based load adjustment computation decreased when any of the client hubs changed regions. Experimental outcomes show that Modified-HBB-LB performs better than the existing load balancing strategies such as HBB-LB, DLB, FCFS, WRR, HDLB, and FIFO by achieving the load balance of the complete system. The Modified-HBB-LB technique reduces the number of migrations tasks (30%, 25% and 20%) as compared to HDLB, DLB, and HBB-LB. The proposed Modified-HBB-LB technique maintains the 3-5% higher performance levels on makespan, completion, and response time as compared to existing comparative techniques.

An Implementation of Modified Blowfish Technique with Honey Bee Behavior Optimization for Load Balancing in Cloud System Environment

The capacity of cloud computing, an emerging paradigm, to lower computer costs, has made it the hottest research area of the day. The most fascinating and alluring aspect of modern technology is what it is giving. The services to its customers over the internet on demand. Security has emerged as the primary challenge impeding the implementation of cloud settings because cloud computing stores data and distributes resources in an open environment. Although cloud computing is effective and promising, there are several issues with data security because the cloud user has no physical access to the data. We suggested a technique using the RSA algorithm to assure the security of the data.
