| dc.description.abstract | The Cloud is a very well-known and accepted data storage that provides many
benefits to users with a pay-as-you-go pricing model, even providing storage
solutions for massive amounts of data. Many users nowadays use different Cloud
services, mainly because the data can be accessed from anywhere via the internet.
Cloud servers are located all over the world, storing massive amounts of data. When
a user uploads or downloads from the Cloud server, the data is exposed to the
internet. This can lead to security issues, such as unauthorised disclosure of data
and lack of user privacy if the data is not properly protected. Many cryptographic
algorithms are used to secure data transformation in the Cloud. The proposed
system is designed to offer a method for properly securing data when transferring
them to the Cloud, utilising various cryptographic techniques, and integrating them
most innovatively and effectively considering the security, data integrity, speed and
data confidentiality. The data is encrypted using a combination of three algorithms
namely AES, ECC and RSA by increasing the security of the data. The keys generated
by the ECC and RSA are combined using an Exclusive OR gate. The AES key is
uploaded into the key management server after being encrypted by the newly
generated key. The data encrypted by the AES key are uploaded into the Cloud
storage. The proposed system is intended to distinguish the features and
functionalities to overcome the drawbacks of the current systems. | en_US |
