- What are the two approaches to attacking a cipher?Cryptography is the study of protecting information. A cipher is a pair of algorithms ―the first algorithm encrypts a message and the second algorithm decrypts the message. In most cases, a unique key is also required to encode or decode plaintext. The Caesar cipher is one of the simplest and most widely known ciphers. It is named after Julius Caesar who allegedly used it to protect important military directives. Every letter in the plaintext is replaced by a letter N positions down the alphabet. For example, if N = 3, then a => d and b => e. While the idea is remarkably simple, it appeared to work in Ancient Rome. Most people there couldn't read, and those who could simply assumed it was a foreign language. Write a program that implements the Caesar cipher. You program will get from standard input the key N, followed by a line of plaintext. . . The key N should be any integer between 0 and 26 inclusive. If this isn't the case, print an error message and quit. Any numbers or…RC4 Decryption/ Complete of RC4 program by writing the decryption part of the cipher? Solve this question only using Matlab Code
- Question 1 Study the scenario and complete the question(s) that follow: Ceasar Cipher The Caesar Cipher technique is one of the earliest and simplest method of encryption technique. It's simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example with a shift of 1, A would be replaced by B, B would become C, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials. 1.1 Write a Ceasar cipher algorithm in such a way that a character D is changed to N. Derive the encryption of the other characters accordingly. 1.2 Based on your algorithm, what will be the encrypted code of the message “my mother is not home". End of Question 1Correct answer will be Upvoted else downvoted. Thank you! Monoalphabetic ciphers are stronger than Polyalphabetic ciphers because frequency analysis is tougher on the former. i) True ii) FalseRSA encrypts, and decrypt operations are: C=Memod(n) M=Cdmod(n) Consider an RSA public key PU = {13,629}. Encrypt the message M = {4} using the public key to get the Cipher key using the RSA Encryption
- 9. Cryptology is the science of making and breaking codes. This lab explores how the idea or functions and their inverses can be used to encode and decode messages. To encode and decode a message, first replace each letter of the alphabet with a positive integer using the following scheme, thus rewriting the original message as numbers instead of words: P- 16 Q- 17 R- 18 S- 19 T-20 Z-26 Blank - 27 A – 1 В - 2 С -3 D- 4 E- 5 F- 6 G- 7 H-8 |- 9 J- 10 K- 11 L-12 М -13 N- 14 O- 15 U- 21 V- 22 W-23 X-24 Y-25 ENCODING: A one-to-one function can be used to encode a numerical message. For example, suppose you want to send the message MATH to a friend, and you have decided that the function f(x) = 3x + 4 will be the encoding function, This function simply describes the procedure used to create the encoded message – in this case multiply by 3 and add 4. First change the letters to corresponding numbers as shown above: 13 1 20 8. Then use these as the input values in f(x).
