Abstract: and LMS is not an easy task.

Abstract:

M-Learning
has enhanced the e-learning by making the learning process learner-cantered.
However, enforcing exam security in open environments where each student has
his/her own mobile/tablet device connected to a Wi-Fi network through which it
is further connected to the Internet can be one of the most challenging tasks.
In such environments, students can easily exchange information over the network
during exam time. This paper aims to identify various vulnerabilities that may
violate exam security in m-learning environments and to design the appropriate
security services and countermeasures that can be put in place to ensure exam
security. It also aims to integrate the resulting secure exam system with an
existing, open source and widely accepted Learning Management System (LMS) and
its service extension to the m-learning environment, namely “the Moodbile
Project”.

.INTRODUCTION

 Student’s
mobile/tablet devices or computer/ laptop are connected to the schools Wi-Fi or
LAN network through which they may illegally exchange information during an
exam. Applying simple policies, such as turning the network down during exams
to cut off any possible communication between students, is not a practical
solution as students in different classes may not take their exams at the same
time. Moreover, the network has to be up during exams in order to be able to
submit students answers to the Exam Server. A dynamic network access policy has
to be generated and applied on each students device according to prede?ned
conditions. Employing an identity based ?rewall with dynamic access policy
seems to be a good solution to be adopted in such a scenario. Learning Management
Systems (LMSs), due to being essential tools of e-learning, have been adopted
by many organizations to establish and provide access to online learning
services. From students point of view, m-learning could personalize their
learning process as well as enable them to collaborate with other students or
teachers. From teachers point of view, they could continue to use LMSs as their
working platform, leaving mobile devices for students. The problem, however, is
that the integration between m-learning applications and LMS is not an easy
task. Indeed, LMSs do not generally contain interoperability standards to
communicate with external applications; they are usually designed as monolithic
or layered systems. Enforcing exam security in open environments where each
student has his/her own mobile/tablet device connected to a Wi-Fi network
through which it is further connected to the Internet can be one of the most
challenging tasks

II. CORE SERVICES AND FUNCTIONALITIES  

The core services of the proposed Exam
Engine are discussed below.

A.     
Random Distribution of Exam
Questions The teacher must have to de?ne a question bank and link them to the
appropriate / respective subject. There are many types of questions i.e.
objective type questions, descriptive kind of questions. In case of objective
type of question. Each question have a set of options. Teacher must have to
specify those options and specify correct answer among them to an able the exam
engine to evaluate student’s answer.

 B.
Authentication of students

 C.
Random Distribution of questions

 III.
SYSTEM ARCHITECTURE

 This
aims to identify various vulnerabilities that may violate exam security in
m-learning environments and to design the appropriate security services and
countermeasures that can be put in place to ensure exam security. It also aims
to integrate the resulting secure exam system with an existing, open source and
widely accepted Learning Management System (LMS) and its service extension to
the m-learning environment, namely the Moodbile Project. To design a Secure
Exam Management System (SEMS) that meets the distinct security requirements of
m-learning environments and to integrate it with the current Moodle/Moodbile
platform. This will result in a complete LMS that is both equipped with secure exam
services and suitable for M-learning. Our intention. of integrating SEMS with a
well-known LMS such as Moodle is so to get the bene?ts of Moodles readymade
services in other learning aspects such as course material administration,
documentation, etc. which have been experienced and appreciated for the last 15
years. However, the proposed SEMS can also work as a standalone secure exam
management system for m-learning environments without integration with Moodle.

 

 

A. Methodology

1) Step1:

In this registration phase every candidate
or user has to register themselves in order to give an exam.

2) Step2:

 After registration the will get an QR code
image which is encrypted information of user information. The same information
will be stored at the server side for admin/ examiner record. The secret key K
is send to admin record, which is used for decryption purpose.

3) Step3:

User will bring that QR code image while
coming for exam then, admin. Examiner will scan that QR code image to check
whether authenticated candidate has come for exam or not, the veri?cation
process done by that user information stored on server or examiner record, upon
veri?ed the admin will send the question paper Q to user account.

 

4) Step 4:

 user
will login to system, to attempt an exam. B. Mathematical Model Let S be the
set of whole system i.e. S=input, process, output Where, – Input is the set of
inputs given to the system. – Process is step or techniques applied to the
system. – Output is outcome of the system.

1) Input: Input = U, QR, K, Q. Where, – U
be the user. – QR be the QR generated from users details. – K be the secret key
to decrypt the encrypted QR code. – Q be question paper.

2) Process:

Step1:

 In
this registration phase every candidate or user has to register themselves in
order to give an exam.

Step2:

 After registration the will get an QR code
image which is encrypted information of user information. The same information
will be stored at the server side for admin/ examiner record. The secret key K
is send to admin record, which is used for decryption purpose.

Step3:

user will bring that QR code image while
coming for exam then, admin. Examiner will scan that QR code image to check
whether authenticated candidate has come for exam or not, the veri?cation
process done by that user information stored on server or examiner record, upon
veri?ed the admin will send the question paper Q to user account.

Step 4

: user will login to system, to attempt an
exam.

3) Output:

Secure Exam Management System (SEMS) to
mitigate the unique exam security threats that exist in m-learning
environments.

C. ADVANTAGES:

 1)
It has a Service Oriented Architecture.

2) Provide better security.

3) Can be access more lightly.

IV. RESULT ANALYSIS:

Input Here, Whole System taken many more
attribute for the input purpose but here author mainly focuses on the Time and
performance of system. Considering few attributes like Unauthorized logins and
access., con?dentiality, Paperless work and time predicted analytical results
of proposed system with respect to existing system.

A = Unauthorized logins and access.

 B = Conditionality.

 C=Paperless work

 D =

V. CONCLUSION In this the design of a
Secure Exam Management System (SEMS) to mitigate the unique exam security
threats that exist in m-learning environments. SEMS offers many exam services
such as: secure and random distribution of examination questions and turbo-mode
assessment. This also helps in prevention of the unattended exam issue, QR code
based authentication system design, preventing students from exchanging their
devices during an examination, conducting exam securely through online or offline
strategies and auditing.
