INTRODUCTION
• Web based application developed in MySQL and PHP.
•It consists of different types of multiple choice questions.
•The answers are evaluated and the marks obtained for each
along with the answer given by the student are stored in the
database.
•The examiner can get the results immediately in various forms
like the general marklist, the detailed general marklist.
•Authentication is provided Via Sessions and the password is
stored in encrypted form in the database.
•Scorecard will be automatically mailed to the examiner.

PROBLEM STATEMENT
•We are going to make an attractive examination portal in which
user can create an account after which user have to signin to
attempt the test.
•Most of the currently existing portals we know have some
problems like crashing or getting hanged.
•We will try to overcome these problems.
•We tried to make this site robust, reliable and it takes less
bandwidth to move from one page to next page.
•We have also working on encryption decryption of the password
using some algo.

FEATURES
 Easy to sing in and sign up.
 It consists of different types of multiple choice questions.
 Test id’s are given by Admin to the user.
 Immediately result is presented after the test.
 Students can see their results anytime.
 Password will be stored in the database in the encrypted
form

STAGES IN EXAMINATION
SYSTEM
•The online test created for taking online test has stages
•Login:-
•There is a quality login window because this is more
secure than other Login forms as in a normal login
window there are multiple logins available.
•More than one person can access to test with their
individual login. Password by which a person enter the
site. Hence it is more secure.
•Reliable than previously used on-line test simulators.

CONT…
Test:
•Test page is the most creative and important page in this
project.
•Subject selection:- From the given choices the candidate
can select his field (like C, C++ and JAVA etc) for taking on
with the test.
Result:
•The whole process of assigning test and evaluating their
scores after the test is done here. If requested trend charts are
displayed at least after five test.

RESEARCH PAPERS
•FPGA Implementation of AES Algorithm
•FSPAlgorithm for Encryption/Decryption
• The Research and Design of Embeded RSA Security

ALGORITHMS
Base 64 algorithm for encryption
Base64 encoding takes the original binary data and operates
on it by dividing it into tokens of three bytes. A byte consists of
eight bits, so Base64 takes 24bits in total. These 3 bytes are then
converted into four printable characters from the ASCII standard.
The first step is to take the three bytes (24bit) of binary data
and split it into four numbers of six bits. Because the ASCII
standard defines the use of seven bits, Base64 only uses 6 bits
(corresponding to 2^6 = 64 characters) to ensure the encoded
data is printable and none of the special characters available in
ASCII are used. The algorithm's name Base64 comes from the use
of these 64 ASCII characters. The ASCII characters used for
Base64 are the numbers 0-9, the alphabets 26 lowercase and
26 uppercase characters plus two extra characters '+' and '/'.

CONTD..
Technically, there is a 65th character '=' in use, but more about it
further down.
The ASCII conversion of 3-byte, 24-bit groups is repeated until the
whole sequence of original data bytes is encoded. To ensure the
encoded data can be properly printed and does not exceed any mail
server's line length limit, newline characters are inserted to keep line
lengths below 76 characters.
What happens when the last sequence of data bytes to encode is not
exactly 3 bytes long? If the size of the original data in bytes is not a
multiple of three, we might end up with only one or two remaining (8-
bit) bytes. The solution is to add the missing bytes by using a byte value
of '0' to create the final 3-byte group. Because these artificial trailing
'0's cannot be encoded using the encoding table, we introduce a 65th
character: '=' to represent '0'. Naturally, this character can only
appear at the end of encoded data

CONCLUSION
• We have tried to implement an examination portal for those
who want to give the exam online or want to practice for the
competitions.
•When the user register on this portal the password is stored in
the encrypted for using some algo.
•User can take the test online of his/her choice regarding the field
and see the progress according to the score card generated.

FUTURE WORK
• The future plan is to come up with a much better technique of
encryption/decryption of password using my own algorithm so
that we can publish some research papers on that.
•We are also thinking to make the site more user friendly and
more attractive.
•I am alsothinking to connect it with social networking site like
facebook,twitter etc.
