Encrypt the given plaintext with the key. Built the key matrix (big size). And show how you get each letter ciphertext (you can do that by making shapes and arrows in key matrix).

No need to draw key matric again and again.

Show all your work. If you just write cipher text and key matric without showing (shapes and arrow on key matrix) that how you get the ciphertext then your marks will be deducted.

key : alphabets

plaintext : smartness

Expert Solution

Answer:

This can be done using playfair cipher encryption mechanism.consider the below image.

In the playfair cipher if two elements are in same row we replace the elements with element right to it.

similarly if two elements are in same column we replace the elements with elements down to the given element.

In other cases we form a rectangle with two elements and replace the element with the element horizontally opposite to it.

Using Python, write a simple application that takes user input of plaintext and key, and encrypt the plaintext with Vigenere Cipher. The application should then print out the plaintext and the ciphertext.

Use Vigenère Cipher to decrypt the following plaintext with the given key key: deceptivedeceptivedeceptive plaintext: wearediscoveredsaveyourself

Given a matrix ? (i.e., a 2D table) of positive integers of size ? × ?. A robot starts at the top- left position ?[?, ?] and must reach the bottom-right position ?[?, ?]. From a position ?[?, ?], the robot can only go either right to ?[?, ? + ?] or down to ?[? + ?, ?]. Let us define the cost of a path the total values of integers in it. Find the least-cost path for the robot...

How to generate a key pair for Alice and Bob Respectively Suppose Alice sends plaintext P= 113, how does she encrypt and whats the ciphertext C? After Bob receives C, how does he decrypts it to get the plaintext P? Suppose Alice sends plaintext P= 113, how does she sign it and what are sent to Bob. How does Bob verify the signature? Suppose Bob sends plaintext P=113, how does he sign it and what are sent Alice. How does...

In Java please You are given a matrix of characters representing a big box. Each cell of the matrix contains one of three characters: " / "which means that the cell is empty; '*', which means that the cell contains an obstacle; '+', which means that the cell contains a small box. You decide to rotate the big box clockwise to see how the small boxes will fall under the gravity. After rotating, each small box falls down until it...

How to proof: Matrix A have a size of m×n, and the rank is r. How can we rigorous proof that the dimension of column space are always equal to the dimensional of row space? (I can use many examples to show this work, but how to proof rigorously?)

Show that in 2D, the general orthogonal transformation as matrix A given by {{cos, sin}, {-sin, cos}}. Verify that det[A] = 1 and that the transpose of A equals its inverse. Let Tij be a tensor in this space. Write down in full the transformation equations for all its components and deduce that Tii is an invariant.

1. Explain and show how the full Keynesian sticky wage model is built. What are the main relationships? Explain briefly what each curve depicts. 2. Imagine that the economy starts off in a situation where the labor market clears. The economy is hit by a shock that reduces consumption demand temporarily. (See e.g. Figure 3.) Show the effects of the shock using graphs. Explain every shift of a curve. What are the effects on the interest rate, consumption, investment, output,...
