Cloud Computing Security: From Single to Multi-Clouds

Now a day‟s rapidly increased use of cloud computing in the many organization and IT industries and provides new software with low cost [1]. So the cloud computing give us lot of benefits with low cost and of data accessibility through Internet. The ensuring security risks of the cloud computing is the main factor in the cloud computing environment, for example sensitive information with cloud storage providers may be entrusted. But „single cloud‟ providers is a less popular with customers due to risks service availability failure and possibly of malicious insiders in the „single cloud‟. A towards movement of „multi clouds‟ or „multiple clouds‟ or „cloud-of-clouds‟ has emerged currently using Shamir‟s Secret Sharing Algorithm. This paper surveys to many running research related paper to single cloud and multi clouds security using Shamir‟s Secret Sharing algorithm and addresses possible solutions and methodology. Main focus of this paper use of multi clouds and data security and reduce security risks and affect the cloud computing user using Shamir‟s Secret sharing algorithm. It is a form of secret sharing, where a secret is divided into parts, which is giving each participant its own unique part, where some of the parts or all of them are required in order to reconstruct the secret. If we‟re going to Count all participants to combine together the secret might be impractical, and therefore sometimes the threshold scheme is used where any „k‟ of the parts are sufficient to reconstruct the original secret.
