To provide an efficient cloud environment for secured cloud based users to improve user authentication and storage security to prevent cyber attacks based on Digital Signature Algorithm (DSA) over Novel Advanced Encryption Standard (AES). Sample dataset considered for both algorithms were N=10 and iterated by G power 80%, threshold 0.05%, CI 95% mean and standard deviation. Split size of training and test dataset is 70% and 30% respectively. The sigmoid function used in DSA maps value between 0 and 1 which helps to improve prediction of accuracy percentage. DSA has significantly better accuracy (80.7%) compared to AES accuracy (59%) and attained significance value of 0.004 (p<0.05). DSA algorithm helps in predicting with better accuracy percentage in cyber attacks over AES.

The proposed work is aimed at providing an efficient cloud environment for secured cloud-based users to improve user authentication and storage security to prevent cyber-attacks based on the Data Encryption Standard algorithm over the Advanced Encryption Standard algorithm. A total of 160 data samples were collected for both the Data Encryption Standard algorithm and the Advanced Encryption Standard algorithm, with a G power of 80%, a threshold of 0.05%, a confidence interval of 95%, mean and standard deviation. size of the training and test datasets is 70% and 30% respectively. The Data Encryption Standard Accuracy is 94% and the Decryption Time value is (66 ns), while the Advanced Encryption Standard Accuracy is 80% and the Decryption Time value is (72 ns), with a significance value of 0.003 (p 0.05). Encryption Standard achieved significantly better authentication than the Advanced Encryption Standard for the identification of lack of security due to cyber-attacks.
