Enhancing Hybrid Encryption Techniques for Secured Data Processing for Small Medium Enterprises in cloud
Mani Goyal, Avinash Sharma · 2021
Cloud computing is a promising area in the field of Information Technology. Nowadays, a good amount of fast, advanced and demanding technologies are available in cloud computing for accessing, sharing, and transmitting large data over the network. Along with this growth, the existence of data hackers and attackers has also increased. Every organization always seek error free and secured data transmission over the cloud. Moreover, the users also expect their data, stored on to the cloud should be more secured, confidential, and authorized. The encrypted data stored at server and it is decrypted at client side. In this article, we proposed cryptographic mechanisms that verify the uniqueness of data stored at cloud is same as original data put by the client. Additionally, we have also explored the existing cryptographic algorithms, namely DES, AES, Paillier and Blowfish for the comparison. For evaluation and performance of an algorithm, we have considered three parameters such as, File size, Encryption time/Decryption time and Memory usage for dissimilar formats like text file, audio file, image file, video file, etc. at different configurations for individual users.
