Cryptography

For this project you will solve the problem presented using Figure 7.17 located in our text and write a 2-3 page report that includes the following: 

  • 2-3 pages of content minimum (does not include cover, abstract or references pages)
  • Paper must conform to full APA guidelines to include a cover page, abstract, headers, introduction, body paragraphs with appropriate headings/subheadings, conclusion, and a reference page.
  • All sources must be cited and references. Remember, unless the statement is common knowledge, you must cite and reference your sources. 
  • You must use at least one peer-reviewed source 
  • Ensure you follow academic integrity policies.  

Problem:  You want to build a hardware device to do block encryption in the cipher block chaining (CBC) mode using an algorithm stronger than DES. 3DES is a good candidate. Figure 7.17 shows two possibilities, both of which follow from the definition of CBC. Which of the two would you choose and why: 

  1. For security?
  2. For performance? 

You must fully explain your justification and reasoning.

Discussion question CIS

Want to know what movies are showing? Need to find a new place to eat? Kids need help with a school project? Have to fix that leaky faucet yourself? With the internet, the answer is just one click away…ok, maybe two or three clicks (or swipes), but it’s there. The internet has made it far easier to solve problems of all types, big and small.

What types of problems has the internet helped YOU solve? Choose one of the topics below. Then, identify a problem you faced and explain how you were able to solve it using resources available on the internet.

  1. Personal Development and Improvement
  2. Do-It-Yourself
  3. Entertainment or Travel
  4. Workplace or Job Hunting

Data Elements

Criteria of security decision-makers use to evaluate the trustworthiness of a data center for critical data?

Data base

 

Throughout the semester, you  learned about different database types and even studied a variety of  database platform. Where do you think data systems will be in five years  from now? How about 10 years from now? Will autonomous system, machine  learning, artificial intelligence, or blockchain play an integral role  in the future of data systems?

Instructions

  • This is a required assignment, worth 15 points. The assignment  must be submitted by the due date. Late assignment are not allowed. 
  • You are required to submit a minimum of two postings. Points will be deducted for not fulfilling this minimum requirement.
  • Apply and use the basic citation styles of APA is required. Points are deducted per the rubric for this behavior.
  • Do not claim credit for the words, ideas, and concepts of  others. Use in-text citation and list the reference of your supporting  source following APA’s style and formatting. Points are deducted per the  rubric for this behavior.
  • Do not copy and paste information or concepts from the Internet  and claim that is your work. It will be considered Plagiarism and you  will receive zero for your work. A second offense results in a zero for  the course. A third is termination from the university.

Differences between policies, procedures, standards and guidelines

 

Many organizations don’t understand the differences between policies, procedures, standards and guidelines.

  1. Define and describe the differences between policies, procedures, standards, and guidelines. For each, find and explain an example. This can be from your current/former workplace, school, ones you find on the Internet, or something fictional that would be applicable to each of the supporting mechanisms. 
  2. Also, answer this question: does it matter if one company calls a policy a procedure and another calls it a standard? What can go wrong if this happens?

Chapter 9 Cluster Analysis

Answer the following questions in a point by point fashion.  NOT an essay. Please ensure to use the Author, YYYY APA citations with any content brought into the assignment.  

  1. For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not to be desirable?
  2. Describe the change in the time complexity of K-means as the number of clusters to be found increases.
  3. Discuss the advantages and disadvantages of treating clustering as an optimization problem. Among other factors, consider efficiency, non-determinism, and whether an optimization-based approach captures all types of clusterings that are of interest.
  4. What is the time and space complexity of fuzzy c-means? Of SOM? How do these complexities compare to those of K-means?
  5. Explain the difference between likelihood and probability.
  6. Give an example of a set of clusters in which merging based on the closeness of clusters leads to a more natural set of clusters than merging based on the strength of the connection (interconnectedness) of clusters.

Requirement: 

Provide a question and Answer Paper with six (6) Questions specifically answered one after the other 

You must use properly formatted APA in-text citations and scholarly references. NO Copying and Pasting from the Internet or other past student paper. There is no redo for plagiarism. 

2. 250 Words:

 

Consider the mean of a cluster of objects from a binary transaction data set.

1. What are the minimum and maximum values of the components of the mean?

2. What is the interpretation of components of the cluster mean?

3. Which components most accurately characterize the objects in the cluster?

Please clearly LIST your response out to all THREE (3) questions and ensure to cite the specific article with the binary transaction of data set. I will be examing this for myself and other students should verify this as well. Provide the Author, YYYY  and specific page number, with any content brought into the discussion.
