Description

This assignment consists of two (2) parts: a written paper and a PowerPoint presentation. You must submit both parts as separate files for the completion of this assignment. Label each file name according to the section of the assignment it is written for. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.

Imagine you’ve been sought out as a guest lecturer at a local university for an ethical hacking course. You have been asked to prepare a paper for the students, as well as a PowerPoint presentation, regarding the use of cryptography in corporations to minimize data theft.

Part 1: Written Paper

  1. Write a four to five (4-5) page paper in which you:
  1. Explain, in your own words, the purpose of cryptography and take a position on whether or not you believe encryption is sufficiently utilized in organizations today. Provide a rationale with your response.
  2. Describe the differences between symmetric and asymmetric encryption.
  3. Select the encryption method you believe is typically more reliable of the two and explain why. Determine if there are any situations where the typically less reliable method could be the better option.
  4. Select one (1) of the common cryptographic systems and justify why you believe it to be the best encryption technology to date.
  5. Describe the common uses of the aforementioned selected cryptographic system and provide a real-world example of how it is used in securing networks, files, and / or communications in the present day.
  6. Create a network diagram of a network and / or in a data flow where your real-world example would exist using a diagramming application such as Visio or Dia.
  7. Analyze current cryptographic attacks that are used in the present day and determine how they can be a detriment to the security where encryption is implemented.
  8. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Your assignment must follow these formatting requirements:

  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
  • Include diagrams created in Visio or one of their equivalents such as Dia. The completed diagrams must be imported into the Word document before the paper is submitted.

Part 2: PowerPoint Presentation

Use Microsoft PowerPoint or an open source alternative, such as OpenOffice, to:

  1. Create a five to ten (5-10) slide PowerPoint presentation in which you:
    1. Summarize the concepts from your written paper in Part 1 of this assignment for the lecture you would give to the class regarding the use of cryptography in corporations to minimize data theft.
Use a professional technically written style to graphically convey the information.

Purpose of cryptography
The main purpose of cryptography is to protect the data transmitted. Cryptography is
necessary in data and telecommunications when communication over any untrusted medium.
Any untrusted medium means any network and particularly the internet (Gary, 2017). However,
cryptography has five main functions which include privacy of data, authentication, nonrepudiation which ensures that the sender has really sent the message, key exchange and finally
integrity: ensures that the receiver gets the message as it was sent.
In cryptography, we have encrypted data which is also known as plaintext. The plaintext
is usually encrypted with ciphertext which will be later decrypted into a usable plaintext. The
process of encryption and decryption is dependent on the type of cryptography scheme used. For
that reason, cryptography is more closely associated with creation and development of
mathematical algorithms that are used to decrypt and encrypt a message.
On the other hand, despite the big push over the last few years on the use of cryptography
to protect the organization and personal data against security breaches, many organizations are
still not using cryptography well. Besides, the fact that there have been a lot of security breaches
where private data is being accessed by outsiders shows that the organizations are not using
cryptography sufficiently.
Symmetric and asymmetric encryption differences
Symmetrical key cryptography, just as the name suggests, involves two people who are
using the same key to encrypt and decrypt the data. Most significantly, some of the symmetric
algorithms are AES, DES and Skipjack. Symmetr...
