摘要：Recently, there has been a dramatic increase in the popularity of cloud computing systems that rent computing resources on- demand, bill on a pay-as-you-go basis, and multiplex many users on the same physical infrastructure. It is a virtual pool of resources which are provided to users via Internet. It gives users virtually unlimited pay-per-use computing resources without the burden of managing the underlying infrastructure Due to cost-efficiency and less hands-on management, data owners are outsourcing their data to the cloud which can provide access to the data as a service. However, by outsourcing their data to the cloud, the data owners lose control over their data as the cloud provider becomes a third party. At first, encrypting the data by the owner and then exporting it to the cloud seems to be a good approach.In this paper we have discussed about cloud computing security issues, mechanism, challenges that cloud service provider face during cloud engineering and presented the metaphoric study of various security algorithms . In this paper, we discuss a number of existing techniques used to pro vide security in the field of cloud comput ing on the basis of different para meters.
