Abstract
The cloud computing security has become the most important problems in its growth.
Encryption has been developed as a solution and plays an important 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 the cloud applications have
significantly increased our data every minute. The current work focuses on cryptography to
provide the protection for sensitive data that exchanged between personal users, companies,
organizations, or in the cloud applications and others during the transfer of data across the
network. Firstly, Data sent from sender to 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 RSA algorithm. Furthermore, we used 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 such
as AES, RSA and hybrid algorithms based on different size of data and their efficiency is
compared. Results of the experiments show that the hybrid algorithm is better in term of
security.
