Assume you are a loyal member of Costco. You have been expecting your membership reward from the company, and you just received a text message on your mobile phone. The message appears to be from Costco:
Costco - Your 3% return is ready: costco.wholesaledividend.com
Before clicking the link in the message, you consider whether this is genuinely from Costco or a phishing attack on you. How can you tell? If it is a phishing attack, what mechanism was most likely used to send the message to you? What actions can you take if you are not sure whether it is a genuine message from Costco? What actions can you take if you are sure this is a phishing attack?
RSA and Diffie-Hellman are important algorithms in public-key cryptography. What are the differences between the two? Assume you intercept the ciphertext C = 105 sent to a user whose public key is e = 7, n = 403. Explain in detail how you will find the private key of the user and crack the ciphertext. What is the plaintext M?
CBC-Pad is a block cipher mode of operation commonly used in block ciphers. CBC-Pad handles plain text of any length. Padding is used to ensure that the plaintext input is a multiple of the block length. Hence, the ciphertext is longer than the plaintext by at most the size of a single block.Assume that the original plaintext is 556 bytes and the size of a cipher block is 28 bytes. What will be the padding? If the original plaintext is an integer multiple of the block size, will padding still be needed? Why or why not?

The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period.

To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3.
