Cloud computing is growing day-by-day in the current world scenario. Organizations are excited and worried at the same time to use cloud computing features as it will require for them to move their data on public cloud. Resource utilization is the main advantage of cloud computing which results in storing data of multiple clients in one place. Private cloud is preferred by the companies but it does not provide all the advantages of cloud computing. Cloud providers are working hard to secure their infrastructure and the stored data in cloud. To secure data, encryption is the most preferred solution. But the problem with traditional cryptographic methods is that they take huge amount of computation power and time in processing the encrypted data.
