RSA and AES Based Hybrid Encryption Technique for Enhancing Data Security in Cloud Computing
Authors: , , , ,
Abstract: Cloud computing security has become the most crucial problem in its growth. Encryption has been
developed as a solution and plays a vital role in the security of information systems in cloud computing. Many
methods are required to secure the shared data. The advanced internet, networking firms, health information, and
cloud applications have significantly increased our data every minute. The current work focuses on cryptography
to protect sensitive data exchanged between personal users, companies, organizations, or in the cloud applications
and others during data transfer across the network. Firstly, data sent from the sender to the network receiver must
be encrypted using the cryptographic algorithm. Secondly, the recipient shows the original data using the
decryption technique. In this paper, we have proposed a model to use a hybrid encryption and decryption process
based on AES-128 and the RSA algorithm. Furthermore, we used the HMAC algorithm to ensure the integrity
and authenticity of data. Our experiment work has been done to explain the time required and throughput for
encryption and decryption of three encrypting algorithms, AES, RSA, and hybrid algorithms, based on different
data sizes, and their efficiency is compared. The results of the experiments show that the hybrid algorithm is
better in terms of security.
