Improving Security with Efficient Key Management in Public cloud using Hybrid AES, ECC and LSB Steganography comparing with Novel hybrid Cube Base Obfuscation

Cloud data security is now the most important issue to be tackled. Data stored in public is at risk if adequate security procedures for data operations and transmissions are not implemented. The objective of this research is to enhance security for data stored in the public cloud using novel techniques of steganography with E-LSB encoding. The objective of this research is to enhance security and storage for data stored in the public cloud using Advanced encryption standard, Elliptical curve cryptography and LSB steganography compared with novel cube based obfuscation. The two groups that are considered are hybrid AES, ECC and LSB steganography and Novel Cube Based Obfuscation methods. This proposed approach makes the data in a nonunderstandable format so no attacker can identify the image and cannot extract steganography images and also occupies less storage space. The sample size considered for implementing this work was N=20 for each of the groups considered. The sample size calculation was done using clinical. The pretest analysis was kept at 80%. Based on the statistical analysis the significance value for calculating execution time was found to be 0.018. In this research it is observed that cube based obfuscation seems to be secure and occupies less storage space than AES, ECC and LSB steganography with 398434282.6 nano sec. Based on the experimental and statistical results achieved it is concluded that cube based obfuscation seems to be secure and occupies less storage space than hybrid AES, ECC and LSB steganography
