Question # 4: Use the Vigenere Cipher method to encrypt the following
“PLEASE SEE ME TOMORROW”. Key stream = ANALOG
Remember: i need a Mathematics solution not computer program
You must show all the steps of your work
Step by step
Solved in 2 steps
- Task 1: Explain how prime numbers are important by evaluating an example based on the RSA algorithm. A. Generate a public/private key pair by (i) First, choosing the two primes, p and q, so that • p = 17, and q is the single digit prime that is closest to the last digit of your national identity number. Second, choosing the value of e to be greater than 5. Third, find the multiplicative inverse d of e showing all the steps and calculations. B. Encrypt a message M = 8, then decrypt the ciphertext to retrieve the original message. Note: You will use the MATLAB code named 'RSA_Spring2023' to finish this task. (iii)Program Specifications: Your task is to write a program that can decrypt a message that has been encoded using a Caesarcipher. Stated another way, you need to find the “shift” for the cipher. Once you have the shift,you know the mapping so you can decrypt the message. the encryption code. use python. def encrypt(text, r): #abcdefghijklmnopqrstuvwxyzresult = ''for i in range(len(text)): # Hello Khoorchar = text[i]if char.isupper():result = result + chr((ord(char) + r - 65 ) % 26 + 65)else:result = result + chr((ord(char) + r - 97) % 26 + 97)return result while True:msg = input("\n\tEnter a String / message e.g. Today is Thursday ")rotation = int(input("\n\tEnter number of rotation e.g. 3 "))print("\n\tOriginal Message is==> ",msg," with rotation ",rotation, " The CypherText ", encrypt(msg,rotation)) No hand written and fast answer with explanation8-1 Discussion: Cryptography V Available on Jun 18, 2022 11:59 PM. Submission restricted before availability starts. As you learned this week, RSA is the most widely used public key cryptosystem. In this discussion, you will apply RSA to post and read messages. For this reflection discussion, use the prime numbers p = 3 and q = 11. Using the public key e = 3, post a phrase about something that you found interesting or relevant in this course. Include only letters and spaces in your phrase. Represent the letters A through Z by using the numbers 01 through 26, and represent a space by the number 32. Treat upper case and lower case letters as the same. Optional: If you want to include punctuation characters, you can use the numbers 27 through 31 for that, but you must inform your classmates that you did. How did you calculate your value for d? As a check, the phrase "A CAB" would be represented by "01 32 03 01 02" and would be encrypted as "01 32 27 01 08".
- Lab Assignment 2: Playfair Cipher Overview: You are required to use the Playfair cipher to encrypt the message: "Butch." You will do the encryption by hand. The key for encryption is “Govern." You will need to show your work for the encryption process. Your submission should be a typed text fileToy encryption scheme. It encrypts plaintexts that consist of only uppercase letters and the underscore character (27 characters total): ABCDEFGHIJKLMNOPQRSTUVWXYZ_ Note that the underscore character is part of the alphabet and will also be encrypted. A key in this scheme consists of 4 digits, each from 0 to 9. Each digit tells how much to shift one character, that is, change it to the character that many positions later in the alphabet. If the shift goes past '_', then we wrap around to the beginning. The key is applied separately to each group of 4 letters in the message. For example, if the message HI_SALLY is encrypted with the key 2407, the H would be shifted by 2, the I by 4, the underscore by 0, and the S by 7. Then we would start over with the first digit of the key, shifting A by 2, L by 4, and so on. So the ciphertext would be: JM_ZCPLE. Give the encryption of the following messages with the key 2641. a. SELL_GME b. FRANZ_IS_MOLE c. DEPLOY_ALL_DIVISIONS1- A simple encryption method is being used to encrypt a small number (called the secret number). The method by which this encryption works is as follows: I. Choose a random seed number II. Calculate the key by multiplying the seed with the secret under modulus 7 III. Finally, multiply the key with the secret to get the encrypted secret
- Ex/ if the following message “paperx” is encrypted by using Hill cipher and converted into ciphertext "EJGPNH" what is the key matrix if you know that the key is (2*2) ?Objective: Given a secret keys "mysecret" and "cs335cryptograph" for DES and AES methods respectively, perform encryption using both DES and AES. Lab: You will be given "DES.py" and "AES.py" programs. And these programs to fit to your solution. Also, you need to install "Cryptodomex" library (Please see the installation file for Cryptodomex) Tasks: In this lab, you will be encrypting messages using DES and AES python program. Submission: Please submit a lab report for following plaintext messages along with code and output snapshots: 1. Plaintext:" Welcome to CS 335" and Ciphertext: ? 2. Plaintext: "Computer Science and Mathematics" and Chipertext: ?You may use a software to do calculations but you have to write down the details. The correspondence of letters table: A 01 B C D E F GH I J K L M 02 03 04 05 06 07 08 09 10 11 12 13 TU V W X Y N O P Q R 14 15 16 17 18 Z space S 19 20 21 22 23 24 25 26 00 4. Decipher the message "NUMBER", which was enciphered using the blocked cipher that sends the plaintext block (x₁, x2) into the ciphertext block (y₁, y2) with 2 (22) = (₂¹9) (2) mod 27.
- If header files are added please provide them The Caesar cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z U V W X Y Z A B C D E F G H I J K L M N O P Q R S T H E L L O W O R L D Normal Text B Y F F I Q I R M X Encrypted Text You are tasked to create an encryption program which takes a key word. The keyword will fill the first part of the shifted array. The remaining letters will fill the end of the array. It should look like this: Key=”TOY A B C D E F G H I J K L M N O P Q R S T U V W X Y Z T O Y A B C D E F G H I J K L M N P Q R S U V W X Z You should have an interactive menu with the following options: 1 Enter Key word //takes new key word and…A [answer] cipher is typically implemented by performing a AND mathematical operation at least two bytes at a time.
