Data Security and Privacy in Cloud Storage using Hybrid Symmetric Encryption Algorithm

Abstract: One of the primary usage of cloud computing is data storage. Cloud provides enormous capacity of storage for cloud users. It is more reliable and flexible to users to store and retrieve their data at anytime and anywhere. It is an increasingly growing technology. Nowadays, many enterprises have started using cloud storage due to its advantages. Even though the cloud continues to gain popularity in usability and attraction, the problems lie in data security, data privacy and other data protection issues. Security and privacy of data stored in the cloud are major setbacks in the field of Cloud Computing. Security and privacy are the key issues for cloud storage. This paper proposes an encryption algorithm to address the security and privacy issue in cloud storage in order to protect the data stored in the cloud.
