A Survey on Kerberos based Parallel Network File System Using Visual Cryptography in Cloud Computing

In today’s world, cloud computing is the developing technology. There exist some security risks in this type of virtual technology. To overcome this, user authentication is used for the defense purpose. This paper gives an outline of kerberos protocol using visual cryptography in cloud. Kerberos is one of the most popular authentication protocol used in networks. This protocol uses a trusted third party for authentication .Our work also focuses onto parallel Network File System(PNFS) which makes practise of kerberos to offer parallel session keys between client web service and cloud web service .Using visual cryptographic , the session key along with username and password is encrypted in the form of an image to reduce the impact of security risks .Thus, our proposed outline makes the kerberos protocol vigorous, protected, escrow-free and provides full forward secrecy.
