### Public Key Cryptography: The Challenge of Factorization

**One of the one-way functions used in public key cryptography is integer multiplication/factorization.** Multiplying two integers is easy, but factoring is hard. The number **1902473** is the product of two primes.

The following figure is the Cipher Block Chaining (CBC) mode to encrypt large messages. Which of the followings statement is *correct* regarding this mode? IV m₁ m₂ m3 C3 m4 C4 m5 C5 If a message contains two identical 64-bit blocks, the corresponding ciphertext blocks are also identical. Switching the order of two cipher blocks will not cause any detectable error in the plaintext. Duplicating a cipher block will not cause any detectable error in the plaintext. Deleting a cipher block will cause some detectable error in the plaintext. m6 E encrypt with secret key C6

Implementing a very basic encryption scheme known as a caesar cipher. The caesar cipher involves shifting every letter in the given string by a given number in the alphabet.

write in python and use the PyCryptodome library for any cryptographic primitives needed two methods countRepetitions that takes a ciphertext as an argument and returns the total number of repetitions between all 16-byte blocksdetectECBMode that takes a ciphertext as input, determines if any repetitions occur, and returns a Boolean value indicating if the ciphertext was encrypted using ECB modeYour code must display the ECB encrypted ciphertext encoded in the hexadecimal format followed by the number of repetitions (in the following line). For example, if you encounter ten blocks with the same ciphertext, then there are nine repetitions of the 1st block so, the number of repetitions is 9.
Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When…

USING KEIL PLEASE.. Ciphers use many bitwise operations for cryptography. Write an ARM assembly program to use ciphers. See the steps below to implement the cipher. In this program, you will implement a "Symmetric Encryption". Create three variables, Plaintext, Key, and Cipher (5 Points) For encryption, design a key value, assign the last nonzero number of your student ID (#900 number) in a variable called “Key” (5 Points) For example: if your 900 number is 90012450. Assign 5 to the variable Key and use it as the Key for encryption. Use this link for the Links to an external site.video to understand Symmetric Key Cryptography and implement that for encryption and decryption. For the variable Plaintext, assign any four-letter word. Encrypt the plaintext using the value in Key and store the encrypted text in the variable Cipher. Test the encryption by decrypting and storing the decrypted text into register R5. Provide comments to each statement
