Abstract: The rapid development of the distributed networks, made the work of sharing the information with large number of people easily. Nowadays distributed networks provide lots of computational resources, reliability, scalability and price to performance. It is useful for so many applications such as telecommunication networks, distributed database etc. Especially it plays a vital role in network file system. In distributed networks the different service providers provide the resources in a very efficient and convenient manner. But the user must register with each service providers, for accessing the resources they have different identity/password for accessing each service provider. Recently some user identification schemes have been proposed but it has some drawbacks. The user will have so many secret information, the security problems can occur and it also increases the overhead of the network. The proposed scheme overcome these challenges by providing a user friendly environment and also enables the security policy by using secure single signon mechanism. It is done by using cryptographic hash function and random nonce’s. This proposed scheme is unable to protect the information disclosure during encryption and decryption of data. In order to provide a high level of security a technique slicing has been introduced. In addition to slicing the data, the encrypt data is hidden in to an image This process is done by using image as a secret key and original data will obtain by using same image as a secret key.

Keywords: Distributed networks, Security, Slicing, Random nonce’s, Cryptographic hash function etc.
