Executive Summary Technology especially the Internet and having everything online is very convenient to everyone at

this day and age. Although the Internet can be a very useful tool, it is also very vulnerable to being

attack in terms of hacking and unauthorized access to online information. With this issue, the study

of how to protect information on the Internet has become a number one topic in the study of digital

security. There are many different ways to prevent information from leaking to unauthorized users

like hacker. One of the methods is to use cryptography to scramble the actual information into a

ciphertext that does not make sense to hackers who does not have to means to decrypt the

ciphertext.

1.0 Introduction This document is the technical manual which can briefly explain about this project. In this manual,

details of the project such as background, scope, version controls and other technical information

will be stated and describe. As the idea of this project is to create an Android application that will

educate the users on the topic of cryptography. The application will contain various different

cryptography ciphers for the users to learn and they are able to use them to encrypt and decrypt

information on their own. In the application, there will be a game included so that the users can

practice analyzing and decrypting different ciphertexts. Therefore, this document will serve as a

brief summary of which different ciphers are used and why, how the ciphers are implemented, the

evolution and the progress of the project, the stakeholders’ involvement and so on.

1.1 Vision

“To provide a user-friendly application where users can both learn and apply cryptography.”

1.2 Context

Our aim is to provide an application where a new user can learn about various

cryptographic and an experienced user can share their encrypted message with another

user. Our application will have a foolproof user interface for any kind of users, no matter

if they have experience or not.

1.3 Project Background

This project is based on ‘Krypto’ application that was from CSCI361 – Cryptography & Secure

Applications. Using this application as a baseline, our project will provide similar functionality to

allow the user to encrypt and decrypt messages or information. Our project will also provide

analyzing functions to help users to analyze the content of a ciphertext which will aid them in

decrypting it. As this is an android application based project, android programming is mainly used

as coding language therefore leading to a lot of research of android programming.


1.4 Project Objective

Objective of this project is working as a cohesive team to develop an Android application where

users are able to do Monoalphabetic, Polyalphabetic, Transposition ciphers and statistical

cryptanalysis.

Minimum requirements are creating Krypto from CSCI 361 into an android application. Functions

included are; index of coincidence(IC), graph, frequency counting (n-grams), etc.

1.5 Roles and Responsibilities

Figure 1.1 Roles and Responsibilities

1.6 Target Users

The target users of our product will be users interested in learning cryptography as well as users who

can use our product as a tool for cryptography.

Potential Customers

● People with interest in cryptography

● People who want to share message with encryption

● Users learning cryptography

1.7 Market Survey

So far from the research we did online, we only found that mainly substitution cipher

puzzles are available.


1.7.1 Common Functions in the Market

• Cryptogram puzzles (substitution cipher)

Our sharing function can convert a user’s plaintext into ciphertext which allows the user

to send it to his/her desired recipient in the form of the ciphertext. Onlookers who don’t

understand this will treat it as random junk letters.

1.7.2 Products Comparison

Our final product is tailored more to the real-world situation as what the sharing function

provides. However, only a handful of them provides interactive help that helps users to

understand better on how the ciphertext is derived from applying the key to the plaintext

and vice versa.


2.0 Requirements Analysis

2.3 Non-Functional Requirement

2.3.1 Usability

This section describes the requirements needed for usability. Our application is

developed with the intention of it being user friendly and it aims to keep training time to

a minimum. The following usability standards are conformed to improve the usability of

application.

Ease of use – the application is easy to use as there are user interface and menu bar

which allows the users to simply just click to perform their intentions.

Simple User Interface – The user interface is simple as there are not much buttons and

each button and text field is clearly texted.

User friendly – Our program is easy to use as there is a user interface which allows the

user to use it intuitively. For example, the menu button is , help options button is

and about button is .

2.3.2 Reliability

This section describes the requirements needed for reliability. Our application provides

reliability for its usage. It will handle large text file without crashing. The following

usability standards are conformed to improve the reliability of application.

Availability - Users can use the application anywhere and anytime even without any

Internet connection.

Error Handling - The program will not crash even for large amount of text. It will also

not crash even if non-English characters are included in the text.


2.3.3 Performance

This section describes the requirements needed for performance. Our application is

dependent on how many characters are there in the text at the time of encryption and

decryption. The more characters there are, the more time it will need to do encryption or

decryption. The performance depends on the hardware components of user. The

following usability standards are conformed to improve the performance of application

Speed - the application will run as fast as possible according to the number of characters

in the text as well as the operating system the application is running on.

Capacity - the application can encrypt/decrypt large amount of text without slowing

down.

2.4 Operating Environment

Our application can be installed on any device running Android Operating System. It can

be installed on Android Operating System (minimum Android 5.0 Lollipop).

2.5 Product Features

Our product is an Android application that educated the users about the different ciphers included in

the application allowing them to learn about the encryption and decryption process. It also teaches

them how to analysis the ciphertext to determine which cipher method was applied and how to

decrypt the ciphertext.

Doing ciphers for educational and real-life purpose. By being able to put your plain text through the

cipher followed by sending it to a corresponding recipient, your message is encrypted so on lookers

will assume that is a random text while it has some meaning behind it.

This product will allow users to apply statistical analysis on ciphertext based on analytics of the

English language.

This product also comes with interactive help functions which shows the user how the ciphertext is

derived from the plaintext or vice versa.

Lastly, our product comes included with a simple game where users can practice decrypting

ciphertexts.

4.0 Implementation

This section describes the implementation phase of the product which includes the

development methodology, development tool, limitations and constraints faced.

4.1 Development Methodology

The development methodology that we have chosen is the Rational Unified Process

(RUP). RUP is an iterative software development model that is able to proactively

resolve project risk. We chose this methodology as it is flexible and able to be tailored to

our needs in this project. This model also allows us to gradually code the program

against the verified requirements as well as test the code against the requirements as we

go along.

Inception

At this stage, we will plan out what are the functional and non-functional requirements of our project

as well as what are the other possible add-on functions that we can include in order to make our

application different from others.

Elaboration

During this stage, we will create relevant classes for the core functions, menu to trigger the

classes to carry out function and verify created classes and functions with requirements.


Construction

This stage will be the construction and development of the product as well as

testing and debugging.

4.2 Development Tools

Summary of the tools that was used in developing this project:

Programming Language

Java was first developed by James Gosling at Sun Microsystems, which is now part of Oracle

Corporation. It was released in 1995 as part of Sun Microsystems’ Java platform. The language has

developed much of its syntax from C and C++. Java applications are usually compiled to bytecode

(class file) that can run on any Java Virtual Machine (JVM). It is object oriented like C++ however

unchanged C++ code will not work in Java in most cases even though they may look similar.

Development Platform

● Android Studio is used to develop the application. It is the official integrated development

environment (IDE) for android app development, based on IntelliJ IDEA. Features that android

studio provides are;

o A flexible Gradle-based build system

o A fast and feature-rich emulator

o A unified environment where you can develop for all Android devices

o Instant Run to push changes to your running app without building a new APK

o Code templates and GitHub integration to help you build common app features and

import sample code

o Extensive testing tools and frameworks

o Lint tools to catch performance, usability, version compatibility, and other problems

o C++ and NDK support

o Built-in support for Google Cloud Platform, making it easy to integrate Google Cloud

Messaging and App Engine

Group Communication

As communication is utmost importance for a group of people who are working on a project, our

team is using WhatsApp as a form of communication platform for efficiency. Communication with

supervisor is also through WhatsApp, if any of us have any query, this channel will allow a faster

response.

Team members will always keep in contact and keep track of the work done to follow the planned

schedule. Everyone on the team is responsible for this project, thus if a problem arises, getting help


from the rest of the team is the first thing to do. Communication through online is done with either

Skype or Discord if the team schedule is too packed to meet up.

Documentation Management

Google drive is a file storage and synchronization service developed by Google. It allows us to store

files in the cloud and do a versioning of the file. This will ensure that when we are editing a file, it

will be latest as we would save it back into the cloud after we are done. With that being said,

collision between uploads may happen thus falls back to our communication structure when we do

edit a file.

4.3 Limitations and Constraints

● Only English language is allowed.

● Special characters are allowed but will not be processed in the application therefore

will not appeared in the final result of the encryption or the decryption process.

5.0 Testing

5.1 Test Plan Identifier

This is the test plan for our program. This test plan will ensure that the program is

functioning as what we have planned and to make sure that it is being developed

accurately. This test plan contains the test approach, how different types of testing will

take place.

5.2 Process Overview

Here are some of the ways that we have followed for the testing process

1. Identify the requirements to be tested and all test cases shall be derived using the

current program specification.

2. Identify which test(s) will be used to test each module.

3. Review the test data and test cases to ensure that the unit has been thoroughly verified

and the test data and test cases are adequate to verify proper operation of the unit.

4. Identify the expected results for each test.

5. Document the test case configurations, test data, and expected results.

6. Perform the test(s).


5.3 Test Strategy

The testing will be done manually and will cover the requirements for all of the different

roles required such as lecturers and administrators.

The following outlines the types of testing that will be done for unit, integration and

system testing. The specific test cases that determines how the testing is done will be

detailed in another document. The template that will be used for the test case is as shown

below

Integration Testing

Integration testing will test the entire product/ application and ensure that a set of

components play nicely together. It is used to expose architecture flaws in the system.

System Testing

System testing is to detect faults that can only be exposed by testing the entire integrated

system. It is mainly concerned with areas such as performance, security, validation, and

load and configuration sensitivity. It ensures that the system can meet compliance in the

real world scenarios within its scope.

Functional Testing

Functional testing verifies end-to-end scenarios that users will engage in.

For example,

Scenario One: Correct plain-text should be returned if an encrypted text is decrypted with

correct key.


Scenario Two: Application should not crash if non-English characters are included in the

text input.

User Interface Testing

User interface testing verifies the user's interaction with the software. It ensures that the

user interface provides the users with appropriate access and navigation through the

functions of the target test. It also ensures that the objects within the user interface function

as expected.

6.0 Conclusion

6.1 System Highlights

6.1.1 Analysis Tools

There are three different analysis tools whereby the users are able to use to analysis the ciphertext to

identify the type of cipher used and also to decrypt the ciphertext. The analysis tools included are

calculation of n-gram frequency, calculation of index of coincidence and the calculation of period

using index of coincidence.


6.1.2 Animated Step By Step Demonstration

For each of the ciphers included in the application, there will be a step by step animated

demonstration of the encryption or decryption process. In this function, the users are able to go

through the encryption or decryption process one step at a time at their own pace. These

demonstrations make use of the input from the user so that they are able to learn about the cipher

using their own example. They are able to repeat the demonstration for as many times as they need to

understand the cipher process.


6.1.3 Sharing function

Users can share their the ciphertext that they’ve created to the recipient(s) after deciding on a key to

encrypt on, allowing them to have a secure way of communication even if an onlooker sees the

ciphertext. They are able to share the ciphertext or the plaintext through any texting application like

the default messaging application or any third-party application that support this feature.

6.1.4 Game

Users are able to put what they have learnt about cryptography, analysis tools and the ciphers included

in the application to test how well they have understand the topic. The game consists of different

levels with ciphertext that was encrypted with different ciphers. They are to solve the ciphertext to

clear each level and eventually completing the game.


6.2 Future Enhancements

These are the enhancements that the project can be further improved on

• Doing email and files ciphers translation which can be stored on the user’s online

database

• Increase the length of the input text

• More game contents or levels

• More complex ciphers can be included

6.3 System Limitations

Speed of encryption and decryption depends on the phone’s operating system.

6.4 Technical Skills Acquired

➢ Java

➢ Android Programming

6.4.1 Java

Java is a programming language that has been in existence since 1996 and has a lot of

users and developers that uses Java products. There should be ample support for Java if a

problem is encountered during development. Java is object-oriented programming and

will be useful for project development as it is possible to divide different portions of the

script to team members. Java is cross-platform and is able to support different operating

systems. Therefore, it eliminates the need for our team to use the same operating

systems. However, it is important to take note of the version of Java being used for this

project. The current latest version of Java is Java 8 and will be used for developing this

project.
