Abstract

Cloud computing is the popular technology and seems to be very promising
for the future trends. In the cloud computing, programs and data are stored and
sometimes processed in cloud. So data and programs can easy be accessible
anywhere, anytime. Cloud computing is also a very applicable solution for
e-government services due to cost effectiveness and efficiency of services.
While it eliminates the need of maintaining costly computing facilities by
companies and institutes, one of the barriers for cloud adoption is still
security concerns. Out of cloud computing is depended upon internet, safety
topics such as, confidentiality, authentication, privacy, and data securities
are the main concerns. In the cloud, users should search encryption
capabilities for preserving and retaining their data. In the same time, they
have to protect the functionality of the underlying cloud applications. There
are many encryption algorithms to encrypt the data. However, there are new
varieties of cyber-attacks developed that threaten the data in the cloud
infrastructure. These attacks allow the encrypted data to be re-encrypted,
making it incomprehensible by the original owner of the data so that it becomes
impossible for the user to decrypt it. This article is written to allow users to
understand the working steps and challenges of the algorithms, comparisons of
the algorithms and possible solutions for the resent threats in the cloud
environment related with cryptography for e-government applications.
