Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Cloud computing uses the internet and the central remote servers to support different data and applications. It is an internet based technology. It permits the users to approach their personal files at any computer with internet access. The cloud computing flexibility is a function of the allocation of resources on authority’s request. Cloud computing provides the act of uniting. Scientific computing in the 21st century has evolved from fixed to distributed work environment. The current trend of CloudComputing (CC) allows accessing business applications from anywhere just by connecting to the Internet. Evidence shows that, switching to CC organizations' annual expenditure and maintenance are being reduced to a greater extent. However, there are several challenges that come along with various benefits of cloud computing. Among these include securityaspects. Our aim is to identify security challenges for adapting cloud computing and their solutions from real world for the challenge that do not have any proper mitigation strategies identified. This non-existence of global standards and guidelines could be help academics to know the state of practice and formulatebetter methods/standards to provide secure interoperability. The identified cloud computing security challenges and solutions can be referred by practitioners to understand which areas of security need to be concentrated while adapting/migrating to a cloud computing environment.

Data Security In Cloud Computing: A Review

Day by day it is becoming necessary and feasible to use cloud storage due to its flexible and secure services. As more number of users are adopting cloud data services different types of threats are troubling them. In such scenario available Cloud Service Provider's security services may seem insufficient to keep user's data safe. User level security mechanism helps to improve security and user's trust in adopting the cloud data services. In our system we have implemented online data encryption mechanism. It is used at user level in which data to be uploaded to cloud storage is encrypted at the time of uploading. Online data encryption helps to fasten the process and saves user's time. To provide better data access control we have used a strong data security technique in which user's data identification credential and salt is used. Data identification credential, partial element of cipher key, is outsourced to cloud for further use in data decryption process. Decryption process is performed at the user level with the help of salt and one time password. In this system user is kept free from key storage and management task as well as it incorporates advanced and more secured technology of containers to store data in cloud. This paper incorporates the detailed analysis of results obtained.

Secure online encryption with partial data identity outsourcing: An exemplar for cloud computing

For the management and control security risks exist on confidential-contained electronic-documents in information age,a high-intensity protection system is accomplished,which is combined with USBKEY identify,public-key encryption,decryption and virtual disk technology.The high-strength authentication of system is realized on user′s identity,also the secure storage efforts on computers contain sensitive information effectively is improved.

Research on electronic-documents protection system based on USBKEY

Cloud computing is a new Internet application mode, has very large scale, virtualization, high reliability, versatility and low cost characteristics. Cloud computing technologies can dynamically manage millions of the computer resources, and on demand assign to a global user. It appears to completely change the old Internet application mode. Since the data was stored in the remote cloud computing platform, thus brought new challenges to information security, for example, disclosure of data, hacker attacks, Trojans and viruses seriously threat user data security. A strict information security scheme must be established, then users can use cloud computing technologies. From based on USB key user authentication, based on attributes access control and data detection, the data security access of cloud computing platform was studied, to provide a secure solution for the user.
