Cloud computing useful for sharing information among the users with unlimited storage space. Data deduplication is method for eliminating duplicate copies of data, to reduce storage space and upload bandwidth in cloud.Toachieve secure deduplication in cloud, convergent encryption has been used.Convergent encryption generates identical ciphertext from identical plaintext files. In cloud computing the duplicate files has to be removed from storage without the provider have access to the encryptionkeys.The problem is there is no efficient and reliable key management.To achieve this Dekey , a new construction in which users no need to manage any keys on their own but they securely distribute the convergent key shares across multiple servers. Encryption mechanisms not preserve the data in the cloud from unauthorized access from both inside attacker as well as outside attacker.To minimize the attacks and also provide security in cloud computing, user behavior and decoy information technology called as Fog Computing has to be implemented.
