Let (Kgen, Enc, Dec) be a semantically secure encryption scheme,that encrypts messages of length l. Show that this scheme alsosatisfies the following properties. 1. Sample a random key K ← Kgen, and encrypt a random message M← {0, 1} l to obtain ciphertext C ← EncK(M). Show that no efficientattacker, given C, can recover the first bit M1 of the message Mwith probability 1. 2. Sample a random key K ← Kgen, and encrypt two random messagesM1 ← {0, 1} l and M2 ← {0, 1} l to obtain two ciphertexts C1 ←EncK(M1) and C2 ← EncK(M2). Show that no efficient attacker, givenC1, C2, can recover the bit of information of whether M1 > M2 orM2 . . .

Scenario: You have been hired as an IT consultant by an entrepreneur starting a small advertising company called MilleniAds. As a start-up, your client’s

company is relatively small and has a limited budget. There are only 10 employees, including a few creative directors, graphic designers, sales staff, a financial

accountant, and an office administrator, with the entrepreneur acting as CEO. The current IT budget cannot exceed $25,000 and ideally should come in as far

under that number as possible. MilleniAds will produce customized sales flyers, brochures, and other branded items, such as letterhead and business cards, that

apply a youthful, fresh perspective targeting millennial demographics. Therefore, the company needs the ability to store and manipulate digital images and to

produce physical copies of their products for their clients. The CEO wants to keep track of inventory, sales, and expenses digitally, but she does not anticipate

having very complex records for the first year. She projects having only a dozen or so accounts but hopes to scale up in the coming years. It would be ideal to

have a simple and user-friendly system for sharing information and files between employees. Many of the employees are millennials themselves who have

indicated that their current desktop PCs are limiting their capabilities and that they prefer using their phones and other mobile devices for their professional and

personal responsibilities. Two of the 10 employees will operate primarily outside of the office, soliciting business from regional firms, and they will need to

access company information while on the road, in their home offices, and at customer sites.

Beyond the specific information given above, you have the ability to fill in the gaps with assumptions or additional details that will make your final project unique

and meaningful to you. If you have any questions, reach out to your instructor for guidance

SELECT ONE either TOPIC A OR TOPIC B

Topics for your Essay, Choose A or B

Essay Length tips–To answer these topics completely, it takes about 2 pages—8-10 paragraphs. Use the topic questions and the scoring rubric to see if your draft responds fully to all parts of the question. A complete, thoughtful answer is more important than word count.

Topic A

In this essay you will address the controversy between free will and determinism. You will go deeper into the problem of determinism by choosing whether it is the predictabilityor the unpredictability of our actions that poses a bigger threat to free will. Using passages from the textbook, explain in detail what determinism is and why determinism threatens the idea of free will.

Now consider these two opposite points of view about our ability to predict behavior:

1. Everything you do is predictable to those who know you well. This predictability means your life is determined by choices beyond your control—Paraphrase from Vaughn, p.258
2. “He sat a long time and he thought about his life and how little of it he could have foreseen and he wondered for all his will and all his intent how much of it was his doing.”—Cormac Mc Carthy (reprinted in Vaughn, p.255)

Explain what these two points of view mean and then give your own reasoned opinion about which point of view is correct. Defend your answer.

Topic B

Describe the theory of knowledge called skepticism. Consider the skeptic’s charge that we can neverbe confident about the reliability of our normal sources of knowledge (perceptions, memory, introspection, and reasoning.) Describe why and how, for each of the 4 sources mentioned, the source is unreliable. Use examples to show your understanding.

If a source of knowledge is unreliable, it means these sources can trick us into believing falsehoods. Does it follow from the fact that we are sometimes mistaken when we rely on these sources that we are always mistaken? In other words, once we admit is possible that we are mistaken, does that mean that we need to admit that we might neverbe correct? How would you respond to the skeptic?
