Arora, R., Parashar, A., & Transforming, C. C. I. (2013). Secure user data in cloud
computing using encryption algorithms. International journal of engineering research and
applications, 3(4), 1922-1926.
In the current paper the authors focuses on providing information regarding security challenges
in cloud computing and helps in the identification of mechanism, challenges which are
experienced by cloud service providers within engineering in cloud and also proposes different
encryption algorithm so as to insure reliability of cloud data. The cloud computing is generally a
form of outsourcing of software, data repository and processing where users ingress applications
and information through logging into any machine which is connected with internet. Data and
applications are provided by third parties and inhabit universal arrangement for protected data
which promotes sharing and cooperation irrespective of location of user or machine utilised.
The authors define cloud computing as the capability to ingress large number of computing that
data are possessed and governed by a third party through the Internet. The authors believe that
cloud computing comprises of hardware, networks, storage, services and interfaces which
provide the platform for users to gain access to the o demand infrastructures, application,
services and computer power irrespective of their locations. The authors also help in highlighting
that computing in cloud generally comprise of the distribution, storage, and handling of data on
the third party’ arrangement, which is not declared in the administration process of customers.
The authors in the article also present that the concept of computing through the cloud is closely
related to service oriented architecture such as Information as a Service (IaaS), Platform as a
Service (PaaS), and Software as a Service (SaaS).1
The authors highlight fact that cloud computing have multiple advantages over traditional
computing which includes greater agility, lower cost of entry, independency among devices,
independency of location and scalability.2

CLOUD COMPUTING
The first security issue which is associated with cloud computing is that it leads to loss of
physical security as a result of sharing of computing resources with other companies and there is
lack of idea and control regarding where resources run. The solution identified to solve the issues
is ensuring secure Data Transfer.3
The second security issue which is associated with computing in the cloud states that the concept
of ensuring data integration which includes transfer, storage, and retrieval relates to changes
which is associated in answer to transactions that are authorized as a mutual standard for
ensuring uprightness of data does not currently exists in cloud computing. The solution identified
to solve the issue is ensuring Software Interfaces which are secure.
The third security issue which is associated with computing is that the customers have the ability
to sue cloud service providers on grounds of violation of privacy rights, which may cause
damage of reputation of providers of cloud services. Concerns regarding cloud computing arises
when the customers do not have idea regarding the rational of requesting for their personal
information and query regarding how their information will be transferred to other parties. The
solution identified to solve the issue is ensuring separation of data.4
The fourth security issue which is associated with cloud computing is confusion regarding who
will control the encryption or decryption key but in all logical sense is should be the customers.
The solution identified to solve the issue is securing Stored Data.
The fifth security issue which is associated with cloud computing is that data logs must be
offered to the regulators and managers of security in cases of Payment Card Industry Data
Security Standard (PCI DSS). The solution which is identified to solve the issue is ensuring user
access control.5
The authors propose various security algorithms for ensuring cloud data security. The first and
foremost public key algorithm which is proposed by the author is RSA, named after its inventors
Rivest, Shamir, and Adleman (RSA) which is mainly an encryption /decryption algorithm which
is unsymmetrical in nature, as in RSA, distribution of public key is done to all users via which a
