Security and Privacy Challenges in Large-Scale Cloud Computing using Signature Generation Algorithm

In this paper, the secure data storage in clouds for a new decentralized access is proposed. Concerns like data leakage are common and can influence the original data owners drastically. Encrypting every data over the cloud which is a huge collection of data is not economically feasible. Signature Generation Algorithm (SGA) is proposed to authenticate the data access from the cloud to ensure the security of the data over cloud and their data sets. Evaluation results express that the secrecy and privacy of the data stored over the network is achieved efficiently and successfully. Keywords— Security, data storage, decentralized access, encryption, Signature Generation Algorithm (SGA).
