Multi Notarized Identity Management in Cloud using Level based Cryptography

Cloud computing is a recently developed with a new technology for complex systems with massivescale services sharing among numerous users. Today most cloud computing system use asymmetric and traditional public key cryptography to provide data security and mutual authentication. Federated Identity Management is a secure single sign-on process between each other and it can enable the portability to share their identity across different networks. In this paper, a multi notarized federated identity system together with level-based cryptography for secure transaction management in cloud is implemented. An effective implementation of this notarized federated identity management together with level-based cryptography not only solves the complex problem of secure key sharing but also provide the access to the number of unknown cloud system can mutually authenticate in notary server.
