Create your own Cryptography using a Substitution Cipher.

Assignment #2 – Cryptography

Cryptography makes up a large part of our technological lives, and in some cases, we never realize that cryptography is working. Do you have a PIN number on your iPhone? The drive is encrypted! Do you use Bitlocker or Cryptdata on your Operating System? Your drive is encrypted! Do you visit most websites? Well most use HTTP Secure via SSL/TLS! Do you use an email service like ProtonMail? Your emails are encrypted… and in all of these cases, you never really interact with the cryptography. Instead, it just happens in the background.

What will we do? Below are a few cryptographic tasks to make sure you’re familiar with various methods of cryptography – from simple ciphers to RSA!

1) Caesar’s Cipher

2) Create your own Cryptography using a Substitution Cipher. Include your SHORT plaintext, the substitution key, along with the cipher text! Please provide Excel or source code if you decide to implement this in a programming language or Excel.

3) Encrypt this number (base 10) using the Public key. (All numbers in base 10 to make it easier).

M = 108

n = 7387 e = 4

4) You received this cipher text message (Base 10) which is supposed to have been encrypted using your public key. Decrypt the message using the following Private key. (All numbers in base 10 to make it easier).

C = 6342

n = 7387 d = 4811

5) Use the following online tool to decrypt an AES 128 ciphertext (base64) using the ECB encryption cipher with a 128 bit key, also given below (Base64 ciphertext). https://www.devglan.com/online- tools/aes-encryption-decryption

KEY: CSITCYBR555HOOD!

Provide the PLAINTEXT output (not Base64).

Why are we doing this? Understanding the basics of Cryptography can help in ensuring that you and your companies stay safe from potential attacks! Using encryption on especially sensitive information is extremely important, and understanding the basics of some of the existing cryptographic methods can help you make more informed decisions on products for yourself and your company. Would you rather have an AES 256 encryption? Or maybe you really need RSA 2048? Do you need a symmetric key algorithm… or an asymmetric? What level of encryption… Does the level of encryption matter.

Learning Objectives This assignment makes use of multiple course objectives

• Implement elementary encryptionhttps://www.devglan.com/online-tools/aes-encryption-decryptionhttps://www.devglan.com/online-tools/aes-encryption-decryption

What court wrote this Opinion and what was the legal issue on appeal?

Writing Assignment

There are three written assignments in this course. Please consult the syllabus and the D2L calendar for deadlines and assignment weight. You will be permitted to drop one writing assignment. Before beginning the first assignment, please read the following for guidance:

1. CONTENT

a. Your paper will be graded for proper grammar. Do not start your paper with “I am going to discuss”. Every student in this class has access to Grammarly. Make sure you use it. Proofread your paper and have a friend or family member proofread your paper.

Review your paper for:

organization (clarity, logic), grammar, spelling, avoid run on sentences and fragments, avoid usage of passive voice, and be sure to capitalize proper nouns.

b. Each writing assignment must be typed, double spaced, and use size 12 font with 1” margins and at least 800 words for the content alone. All paragraphs should be in a justified format. This word requirement does not include your citation to the source(s).

c. You may use a block format or, you may indent. If you choose to ident, the first line of each paragraph must be indented by 0.5”. The paper must be submitted through the D2L dropbox feature.

d. All work needs to be your own. Answer in your own words. Do not copy and paste from the case and do not use quotes. I do not expect you to be lawyers but do expect you to really dig in to facilitate valuable growth in critical thinking and communication skills. This may be challenging at first but stick with it! It can be very rewarding to see your case analysis skills and legal terminology improve over the semester!

e. Originality Check and Word Count is enabled for each assignment. No quotes allowed. The entire writing assignment must be in your own words. The plagiarism software will be turned on so NO QUOTES, NO COPYING AT ALL. You can check your own originality count. If you do not know how to do that, contact the MTSU Help Desk online (24/7) or at 1-615/898-5345.

2. CASE BRIEFING AND ANALYSIS

I understand that you are not attorneys. However, I do want you to be able to learn how to structure an analysis of a case. Each writing assignment will include a case “briefing” to structure your analysis. You will then be called upon to apply that case to a fact pattern. Your case briefing should use the following format:

How are the four megatrends shaping the local and global interrelations among nations?

1. As described in “The New Population Bomb: The Four Megatrends”, How are the four megatrends shaping the local and global interrelations among nations? What are the major implications?
2. Howe and Jackson argue that demographic storms, from the premature aging of China’s population to the implosion of Russia’s, will increase the risk of social and political upheaval. Do you accept their analysis? Why? (make sure you justify your position with examples from the readings).

Describes the results of your assessment of the labor market from which your selected organization draws candidates for open positions.

Labor Market

Write a 1000-1200 word paper that:

· Describes the results of your assessment of the labor market from which your selected organization draws candidates for open positions.

· Explains the population, demographics of the population, levels of education, and how much training may be required to prepare new workers drawn from this pool for positions in the firm.

· Use regional economic corporations, US Department of Labor and other sources to provide data.

In addition to the requirements above, your paper:

· Must be double-spaced and 12 point font

Describe the controversial topic and cultural identifier. Explain the connection between the controversial topic, the cultural identifier, and the role of social justice.

The field of education is vast and complex with many stakeholders involved, sometimes controversies arise. These controversial issues usually begin with a single or a series of historical events. There also are usually arguments on both sides of the issue, both supporting and opposing. Since these issues may cause strife and division, federal and state policymakers, state and local administration, teachers, students, parents, and community members attempt to offer solutions to these controversial issues. 

Relating to these controversial issues are cultural identifiers which can be defined as characteristics or conditions that make each individual unique. Usually, one or more cultural identifiers are at the root of controversial issues. Understanding both the controversial issue and the related cultural identifier can help stakeholders find the best, most equitable, and most ethical solution for everyone involved.

Throughout this course, you will be working on a 1,000-1,250 word assignment on a controversial topic involving a cultural identifier and the implications of the controversial topic on K-12 education. Your first draft of the assignment will be due in Topic 4, and you will be required to submit it to the peer review forum on day 1 in Topic 5, and your final version will be submitted in Topic 7. 

Part 1

Select a controversial topic related to diverse cultures and communities currently affecting K-12 education. Potential topics could include body image, citizenship status, plastic/cosmetic surgery for teenagers, bathrooms for transgender students, ethnic curriculum/classes, religious clothing, prayer in schools, or other topics that involve a supporting and opposing side and at least one cultural identifier. Utilizing sources found in the GCU Library and the EDU-330 assignment Guide, complete a 500-750 word brainstorming assignment on your topic and address the following prompts:

• Describe the controversial topic and cultural identifier. Explain the connection between the controversial topic, the cultural identifier, and the role of social justice.
• Summarize the key historical events that have significantly affected your specific controversial topic.
• Summarize the topic in the context of K-12 education, including the related cultural identifier and any associated controversies.
• Identify current scholarly statements for the controversial topic, including at least one supporting and one opposing.
• Describe how this controversial issue could affect future teaching practices and how it could affect future students.
• Summarize related policies or methods that have been implemented at the local level including both districts and schools as a solution to the controversial issue.­­­

Part 2

Begin conducting to support your opinion on the controversial issue. Collect a minimum of three scholarly resources from the last five years to support your rough draft due in Topic 4. Submit a 50-150 word summary for each of the three articles, including how the articles apply to your chosen topic.­­

describe how your project will integrate the insights from each of these disciplines to produce new knowledge.

Disciplinary Description Assignment

In your mid-term assignment, you will be crafting a defense of an interdisciplinary approach regarding a research question that interests you. Imagine that you are working on a specific research question in your field (perhaps you already have a suitable project in mind based upon your coursework). In a well-written essay of at least 10 pages, you will describe the disciplines you will employ to address this question and you will explain how you’ll integrate these disciplines in your project.

In order to complete this assignment, you will find primary texts in your areas of study (you need to draw from at least two areas)–texts like Introduction to Philosophy, The Basics of Engineering, etc.–and you will utilize Repko’s methodology of describing a disciplinary perspective to clearly specify your understanding of the fields. In addition to using those primary texts and the Repko text, you will need to refer to deeper texts in your field to demonstrate your rich understanding of how these fields work. 

After describing the disciplines you utilize in terms of the disciplinary perspectives method (phenomena, method, concepts, etc.), you will go on to describe how your project will integrate the insights from each of these disciplines to produce new knowledge. This will take some imagination, as you can’t possibly know where a research question will take you. 

To give you a better idea of what I’m looking for, I’ve provided two samples below. The first sample is a very rough version of this assignment that I created in the process of developing  this final project  (Links to an external site.) ,

Submit using good Chicago Manual of Style format. Next week, I’ll be providing further information on this project as well as a rubric, but this should be enough information to get you started. 

What are the exploit vectors and vulnerabilities threat actors are predicted to take advantage of?

Advanced persistent threats (APTs) have been thrust into the spotlight due to their advanced tactics, techniques, procedures, and tools. These APTs are resourced unlike other types of cyber threat actors.

Your chief technology officer (CTO) has formed teams to each develop a detailed analysis and presentation of a specific APT, which she will assign to the team.

This is a team assignment, and the team members that were selected by the instructor in the previous assignment will work together. It is up to the team members to decide who is responsible for contributing to the sections of the paper. Remember, if a member fails to complete his or her part of the work, the team is still responsible for all sections.

Note that you are required to complete a peer review for yourself and for each member of the team. The peer review template is provided in the Activities folder.  

Your team’s report should use the  The Cybersecurity Threat Landscape Team Assignment Resources to cover the following five areas:

Part 1: Threat Landscape Analysis

·

· Provide a detailed analysis of the threat landscape.

· What has changed over the past year?

· Describe common tactics, techniques, and procedures to include threat actor types.

· What are the exploit vectors and vulnerabilities threat actors are predicted to take advantage of?

Part 2: APT Analysis

·

· Provide a detailed analysis and description of the APT your group was assigned. Describe the specific tactics used to gain access to the target(s).

· Describe the tools used. Describe what the objective of the APT was/is. Was it successful?

Part 3: Cybersecurity Tools, Tactics, and Procedures

·

· Describe current hardware- and software-based cybersecurity tools, tactics, and procedures.

· Consider the hardware and software solutions deployed today in the context of defense-in-depth.

· Elaborate on why these devices are not successful against the APTs.

Part 4: Machine Learning and Data Analytics

·

· Describe the concepts of machine learning and data analytics and how applying them to cybersecurity will evolve the field.

· Are there companies providing innovative defensive cybersecurity measures based on these technologies? If so, what are they? Would you recommend any of these to the CTO?

Part 5: Using Machine Learning and Data Analytics to Prevent APT

·

· Describe how machine learning and data analytics could have detected and/or prevented the APT you analyzed had the victim organization deployed these technologies at the time of the event. Be specific.

Notes

· Use additional sources of information but also describe the concept in layman’s terms.

· Use visuals where appropriate.

· While quality is valued over quantity, it is expected that a quality paper will result in a minimum length of 10–15 pages.

· You will be assigned an individual grade for this assignment based on your contribution to the overall project.
