online exams have not been widely adopted though Internet has contributed to
the spread of online education. An online exam takes place over the insecure Internet and the proctor is not near the examinee.
INTRODUCTION
The security of online examinations remains a problem. Simpli?cation and automation of educational processes comes with adopting the online exam technique. This article dicusses issues of security and cheating for online exams to remove the requirement for human intervention in secure
online exam management so as to capitalize on the advantages
of online processes. The en- hanced Security Control system in the Online Exam (SeCOnE)
which is based on group cryptography with an e-monitoring is proposed. it can pro-
vide teachers with better evaluation standards for students as the SeCOnE
systemenablesmany kinds of tests to be given online.
REQUIREMENTS FOR A SECURE ONLINE EXAM
-Accessibility:Online exams should be possible without re-
gard to location and time
-Management: problem
creation, problem sheet distribution, answer sheet collec-
tion, marking, grade posting, and handling of appeals etc are the problems that have to be solved.
-Monitoring
-Authenticity:
-Integrity
-Secrecy
-Copy Prevention and Detection
AN ENHANCED SECURITY CONTROL
IN THE SeCONESYSTEM
Architecture of the SeCOnE System:
all entities in the SeCOnE system per-
form their roles as members of either group . One group re-
ceives the problems and the right answers and then
distributes the problems and collects the answer sheets. For secure communications among group members,
they use the symmetric keys created by the Dif?e-Hellman key
exchange.

Enhanced Security for Online Exams Using Group Cryptography
Abstract
Online exam is field that is very popular and made many security assurances. Then also it fails to control cheating. Online exams have not been widely adopted well, but online education is adopted and using all over the world without any security issues. An online exam is defined in this project as one that takes place over the insecure Internet, and where no proctor is in the same location as the examinees. This project proposes an enhanced secure filled online exam management environment mediated by using remote monitoring and control of ports and input. The target domain of this project is that of online exams for any subject’s contests in any level of study, as well as exams in online university courses with students in various remote locations. This project proposes easy solution to the issue of security and cheating for online exams. This solution uses an enhanced Security Control system in the Online Exam (SeCOnE) which is based on group cryptography with an e-monitoring scheme.

Enhanced Security for Online Exams Using Group Cryptography
Objective
To improve the quality of Online examinations and to maximum utilize these type.
Existing System
Different cheating patterns exists in current system including copying the answers of others, exchanging answers, searching the Internet for answers, using the data and software saved on the student’s local computer and discussing the exam by e-mail, external storage devices.
Disadvantages
► Level of communication between teachers and students decreases.
► The tendency to cheat by students increases.
► The system must rely on students’ honesty or their having an honor code
Proposed System
► This project proposes a solution to the issue of security and cheating for online exams. This solution uses an enhanced Security Control system in the Online Exam (SeCOnE) which is based on e-monitoring scheme. The e-monitoring provides a proctor function to remote examinees to prevent cheating, and thus removes the requirement of having to go to a fixed location. The target of this project is online exams of any type and exams in online university courses with students at remote locations.
► Project proposes administering an online exam at a fixed time with the same questions for all examinees, just like an off-line exam, but without restricting the physical location of the examinees. As the SeCOnE system enables many kinds of tests to be given online, it can provide teachers with better evaluation standards for students and may contribute to improving the quality of education.
Scope of the project
This system can provide the secure and prevent the online exam. It can find which candidate cheats the exam through the internet or getting the answer from the local hard disk. It does not allow the cheated candidate to write the online exam.
Advantages
► Online exam management system having some monitoring method to prevent and to detect cheating.
► Without regard to location and time.
► Avoid intercepting or interfering with communications during an online exam.

Security Control system:
This security system for online exam is very effective technique. It can restrict the students who they try to access the answer from the local hard disk or chatting with the friends or searching the answer through the internet. These behaviors can restrict by using this techniques.

Input: enter the registration number
Output: it show the result of the corresponding registration number
► Database Design
► System Architecture
Advantages
► It can allow the candidate to attend the exam in convenient time.
► Staff can contact the various exams in this application.
► No need to monitor the candidate during the exam time.
► It does not allow the candidate to get the answer from the internet or from the local hard disk.
► If the system have suspect as a cheat it does not allow you to attend the exam.
► It can correct the answer automatically.
► Finally it will display the result of the corresponding registered candidate.
Future Enhancement
Future research will consider the effects of malicious entities in the system, and the processes involved in handling failures. The system can also be implemented with the webcam for monitoring the candidate during the online examination. The system can also implement in the WAN network.
