In the symmetric cryptography approach, both the sender and the receiver must share a secret code or secret key.

Suppose we use the paint-mixing trick with numbers, where  Alice’s private number is 20, Bob’s private number is 15, and the public number is 2. Then Alice’s public-private number is [Alice] Bob’s public-private number is [Bob] and the secret number that Alice and Bob have shared is [Secret]

Given the plaintext GOODLUCK, and the OTP secret key HNAPFSMQ, what is the encrypted message (or cipher text) obtained after encrypting the given credit card number with the given secret key using the one-time pad encryption method with letters? Write the encrypted message into last row of the two tables below, one letter in one cell,  enter the first four letters in the first table, enter the last four letters in the second table. Make sure to write only UPPERCASE letters and no spaces, no numbers, no other characters. Note that the numbers in the 2nd row represent the letters in the plaintext and the numbers in the 4th row represent the letters in the secret key. G O O D 6 14 14 3 H N A P 7 13 0 15 [n1] [n2] [n3] [n4]   L U C K 11 20 2 10 F S M Q 5 18 12 16 [n5] [n6] [n7] [n8]

The set of specific, sequential steps that describe exactly what a computer program must do to complete the work is called a(n) ________.

Suppose you apply linear search to search for number 20 in the sorted list given in the second row of the table below (the numbers in the top row are locations of the numbers in the search list). 1 2 3 4 5 6 7 8 9 10 11 12 13 3 5 10 19 22 23 31 41 43 45 49 50 61 How many numbers does linear search check in this case?

Which of the following about variables in computer algorithms or programs is FALSE?

A set of associations linked to a concept in memory is called a [1], while the mental framework for understanding how a product category works is called a [2]. Options: A) Schema B) Knowledge Structure C) Prototype D) Script  

In class, we discussed how consumers’ attitudes are formed through high-effort processing, particularly when they have strong motivation, ability, and opportunity (MAO). When this process is based on their cognitions (thoughts), it can include approaches like: Direct or imagined experience Reasoning by analogy or category Values-driven attitudes Social identity-based attitude generation Choose one of these approaches and explain how a brand or product outside of the examples we provided in class uses this strategy to shape consumer attitudes. Be sure to: Identify the approach. Provide a real-world example. Explain why it is effective in shaping positive attitudes. Please limit your response to a maximum of 100 words.

Match each characteristic of attention with its correct description:

Write a method named squareOfStars that takes exactly one parameter of type int and displays a solid square of asterisks (*)  whose side is specified in the method parameter. For example, if the method parameter has value 3, then this method will print out the following: *********
