Please be sure to read all of this assignment description carefully. It’s very detailed. It describes two separate things. However, all items will be submitted in ONE Word document.
The portfolio that contains elements you have been working on throughout the course; and  
The final p (problem analysis) that you will include as part of the portfolio.  
Let’s look at the BIG picture first, the final portfolio.    
What is a portfolio? 
A portfolio is a collection of items organized in a notebook, file, or a similar format. By collecting this information throughout a course, you can clearly see the connections among assignments as well as the progress you have made. In ENGL110, your portfolio will reflect the work you have done in a specific discipline or topic, ending with the analysis of a problem you have explored. Here are the required elements of the portfolio. The required sections are included in the template.

This is the final problem analysis paper that is the culmination of all the work you have done in the course.  Please see the complete description of the paper below
Assignment Instructions 
This analysis project requires you to tackle a problem within your field of study by first exploring it, its causes, and its impacts.  Then, if you want, you can recommend one or more practical solutions to solve the problem.   
After deciding on the problem you wish to tackle, begin building questions about it. Your goal for the analysis is to answer the questions through your sources. Finding multiple angles and perspectives is ideal so that you explore those possibilities in the final paper before settling on your recommendation.  Be sure to identify what is at stake.  
Here are questions to help guide your analysis: 
What is the problem being addressed (explain, describe, and “prove” that it exists)?  
Who is affected by this problem?  
Why does this problem exist? (Identify the root causes.)  
Why does the problem persist? (Identify the major factors that contribute to the problem’s ongoing presence.)  
What is at stake if the problem is not solved? 
  If you decide to include a solution, use these questions to guide you:   
Who can take action?  
What should they do, exactly?  
Why would this help? 
What are the positive and negative aspects of your solution(s)?  
PURPOSE:   To analyze a problem and possibly provide a solution 
AUDIENCE:   Classmates, others interested in the field 
LENGTH:   900 – 1,000 words (Times New Roman font). Please do not go significantly (~10%) under or above the word count requirement. This word count includes only the paragraphs in your final  (not the Works Cited/References page or previously submitted sections).
SOURCES:   5 (five) sources  (These may include sources you used in previous assignments. Going under this number will cost points in grading.) 
FORMAT:   The citation style that is appropriate for your discipline  
Submit your assignment as a Word document attached to the assignment link so it can be automatically processed through Turnitin. Use either the MLA or APA template provided. You can save the template with a title like this: Your Name Portfolio Final Pa.   

  
Instructions
Each Research Paper: Topic Proposal and Outline must include the following 3 items:
1. A brief (at least 3–4 bullets with 1–2 sentences per bullet) overview of the research topics of your paper – you will need to address these in the Research Paper:  This will be titled “Research Objectives”.
2. A list of at least 3 questions (in a numbered list) you intend your research to ask and hopefully answer. These must be questions that will require you to draw conclusions from your research. These must not be questions to answer your research objectives. This section will be titled “Questions.”
3. At least 3 initial research sources, 1 of which is an academic journal or other peer-reviewed source. These should match APA formatting of sources.
Example formats for Topic Outlines (an example, not a template):
Research Objectives
· Briefly describe the overall concept of system integration.
· Discuss the traditional approach of big-bang integration including the major advantages and disadvantages of this approach.
· Discuss the traditional approaches of top-down and bottom-up integration and their major advantages and disadvantages.
· Discuss the traditional approach of mixed integration, combining the desirable advantages from the top-down and bottom-up integration approaches.
Questions
1. Why is system integration an important step in the software development process?
2. Why has big-bang integration not survived as a useful testing method?
3. Why have top-down and bottom-up integration not been replaced by more modern methods?
4. Why would you use mixed integration all the time rather than sometimes using top-down and bottom-up integration exclusively?

Prepare
First, download and install CrypTool.
If using a Windows® PC, install CrypTool 1.
 If using a MAC PC, install JCrypTool.
Note: In order for the CrypTool program to function, you must first OPEN a text file. Only then will items on the toolbar become enabled.
Additional information for this assignment is covered in the Assignment 3 — CrypTool Lab document.
Part 1.1
Identify the digital signature schemes and MAC schemes that are supported by CrypTool. For each scheme, determine the key sizes supported by CrypTool and which key sizes are recommended by NIST.
Encrypt text using two digital signature schemes, measure the execution time for key generation (if applicable), signature generation, and signature verification. Measurements should be performed multiple times, and then the analysis should use the average time for comparisons. In order to obtain measurable results, you will likely need to use long messages (i.e., 5 MB or larger).
Record results and draw conclusions. Identify the encryption algorithm used. Discuss the results of the measurements and any variations or trends observed when comparing the results from the group members. Report the results and the analysis. Be sure to include details on the measured results and details on each member’s computer (i.e., processor type, speed, cache size, RAM size, OS, etc.).
Part 1.2
Using CrypTool, generate an MD5 hash for a small plaintext document.
Record the hash result (cut and paste).
Change one character in the plaintext and regenerate a hash on the changed text.
Record the hash (cut and paste into your report).
Do you think you could find a hash collision (that is, can you find two different texts that produce the same hash)? Experiment a few times and draw a conclusion about whether this can be done easily.
Part 1.3
Generate a large prime (at least 20 digits long) and a short prime (less than 10 digits in length) (HINT: Individual Procedures RSA Cryptosystem Generate prime numbers).
Determine which factorization algorithms are implemented within CrypTool (Indiv. Procedures -> RSA Demonstration -> Factorization of a Number).
Identify the characteristic features of these algorithms by reading the “Factorization algorithms” help within the tutorials section of CrypTool’s built-in help.
Try to factor the primes using some of these methods.
Report your results, identifying the methods you used. Be sure to include how long the factorization took (or how long it was estimated to take if it was not completed in a reasonable time).
Now, just enter numeric values to be factored (again, one long number and one short one).
What are the results? Were factors found? Are you good at guessing prime numbers?
