Now-a-days cloud computing places a vital role in data storage and information transmission process. During this process, information consists of several sensitive and secretes data that requires the authentication for eliminating the unauthorized access. Traditional methods such as like encryption and decryption cryptographic techniques process but they are fail to maintain the authorization, trust and security in geographically distributed environment. Initially, the data has been analyzed that is stored in the cloud by performing the Naccache–Stern cryptosystem based homomorphic encryption process. The system generates the key which used to encrypt the shared information that difficult to access by intermediate user. The user access the information by performing the encryption process which built trust between user and cloud storage provider. This effective homomorphic encryption process successfully maintains the data security while accessing and storing data in cloud effective manner. Then the efficiency of the system is evaluated using experimental results and discussions.
