Hybrid AES-Modified ECC Algorithm for Improved Data Security over Cloud Storage

Abstract

As cloud computing has been increasingly used by businesses to address their data storage and processing needs. The private data can be stored and retrieved by the end user through remote storage using an affordable Internet connection in the cloud computing environment. The user may access the information whenever they want, from wherever. However, the data transmitted through the cloud is not always secure and data integrity and authentication may be compromised as the end user is only able to access the data through a third party. Cloud computing also enables numerous people to access information simultaneously over separate Internet connections, which might increase the risk of information loss or leakage. Several cryptographic methods like DES, 3DES, Blowfish, RSA, Diffie-Hellman have been developed to guarantee the safety and privacy of stored data. Since the business clients hesitate to adopt the cloud due to its less security. This paper suggests a method for exchanging cloud data that is both secure and efficient. The proposed method is mainly focused on higher security for the cloud computing platform by applying hybrid Modified Elliptic Curve Cryptography (MECC) method with the Advanced Encryption Standard (AES). In comparison to other methods, the hybrid ECC-AES strategy takes less time to encrypt and decode data owing to its reduced key size.
