- 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?

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?arrow_forward

Problem Description: • • Design a class named Person and its two subclasses named student and Employee. • Make Faculty and Staff subclasses of Employee. • A person has a name, address, phone number, and e-mail address. • • • A person has a class status (freshman, sophomore, junior and senior). Define the status as a constant. An employee has an office, salary, and date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString() method in each class to display the class name and the person's name. 4-1. Explain on how you would code this program. (1 point) 4-2. Implement the program. (2 point) 4-3. Explain your code. (2 point)arrow_forwardSuppose you buy an electronic device that you operate continuously. The device costs you $300 and carries a one-year warranty. 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. Your expected total cost to the nearest $100 is _________,…arrow_forward
