ABSTRACT
Cloud Computing becomes the next generation architecture of IT Enterprise. In contrast
to traditional solutions, Cloud computing moves the application software and databases to the
large data centers, where the management of the data and services may not be fully trustworthy.
This unique feature, however, raises many new security challenges which have not been well
understood. In cloud computing, both data and software are fully not contained on the user's
computer; Data Security concerns arising because both user data and program are residing in
Provider Premises. Clouds typically have a single security architecture but have many customers
with different demands. Every cloud provider solves this problem by encrypting the data by
using encryption algorithms. This paper investigates the basic problem of cloud computing data
security. We present the data security model of cloud computing based on the study of the cloud
architecture. We improve data security model for cloud computing. We implement software to
enhance work in a data security model for cloud computing. Finally apply this software in the
Amazon EC2 Micro instance.

MODULES DESCRIPTION:
Three-layer system Construction module
The model used three-layer system structure, in which each floor performs its own duty to ensure
that the data security of cloud layers. The first layer: responsible for user authentication, almost
this is two factor authentication, but free cloud providers use one factor as examples eyeos,
cloudo, and freezoha. The second layer: responsible for user's data encryption, and protect the
privacy of users through a certain way by using one symmetric encryption algorithms. Also
allow protection from user. The third layer: The user data for fast recovery this depends on the
speed of decryption.
Storage data Module
We make improvement to data security model in cloud computing. We implement software to
the cloud provider. This software is implemented with two factor authentication. This software
compares between eight modem encryption algorithms. This comparison based on Statistical
Tests to get the most security algorithms. This software gets the faster and the highest security
algorithm based on cloud infrastructure. So we proposed to cloud provider the suitable, more
security encryption algorithm to its platform.
Transmission data Module
Clouds are massively complex systems can be reduced to simple primitives that are replicated
thousands of times and common functional units, These complexities create many issues related

to security as well as all aspects of Cloud computing. So users always worry
about its data, so users can transmit the data’s to others to make a copy of data so as not to lose
it.
Processing data Module
A proposed software solves some problems. This software implements strong API access
control, by using two way authentications. This software encrypts and protects data, by using the
highest security algorithm. This software analysis data protection at lAAS, we use Amazon EC2
as a case study to run this software. This software ensures that protection algorithm is highest
security algorithm to satisfy the user, by using NIST statistical tests. This software Ensure faster
retrieval, when using faster encryption/decryption algorithm
