The problem at the center of RSA is finding the e’th root of the ciphertext c modulo N where N = pq is a product of (distinct) primes. This is hard to do for large N if you don’t know the factors p and q, but once you know p and q it becomes easy! Write a finction findRoot(c,e,p,q) which solves the equation xe ≡ c mod N for x where N = pq
Eve uses RSA to send a message to Bob, using Bob's public key. Later, at a cock- tail party, Eve sees Bob and asks him if the message has arrived and Bob confirms it. After a few drinks, Eve asks Bob, "What was the ciphertext?" Bob gives the value of the ciphertext to Eve. Can this endanger the security of Bob's private key? Explain your answer.
Alice and Bob are using the ElGamal cipher with the parameters p = 131 and a = 2. Alice makes the mistake of using the same ephemeral key for two plaintexts, ₁ and ₂. The eavesdropper Eve suspects that x₁ = 87. She sees the two ciphertexts y₁ = 87 and y₂ = 121 in transit; these are the encryptions of ₁ and ₂, respectively. a) What is the masking key km? b) What is the plaintext x₂?
Alice and Bob agree to use the prime p = 1373 and the base g = 2 for communications using the Elgamal public key cryptosystem. Bob chooses b = 716 as his private key, so his public key is B ≡ 2716 ≡ 469 (mod 1373). Alice encrypts the message m = 583 using the random element k = 877. What is the ciphertext (c1, c2) that Alice sends to Bob?
Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzl. We conduct a known-plaintext attack against an LFSR. Through trial and error we have determined that the number of states is m = 4. The plaintext given by 01100101 —D ХоXјX2XҙX4X5X6X7 when encrypted by the LFSR produced the ciphertext 10010100 — Уo У1 У2 Уз Уз У5 У6 Ут- What are the tap bits of the LFSR? Please enter your answer as unspaced binary digits (e.g. 0101 to represent P3 = 0, p2 = 1, Pi = 0, po = 1).
In the Elgamal encryption scheme, Bob's public key is fixed, but Alice uses a fresh random i e {2,...,p – 2}, and hence a fresh random kg, whenever she wants to send Bob a message. What happens if Alice uses the same i for ecrypting multiple messages? Can Trudy recover any meaningful information from the ciphertexts?
Alice uses RSA to send a key to Bob for use in encryption of future messages. The key is the word "CINEMA" and the encoding from letters to numbers is done using the ASCII: A = 65... Z = 90, space = 99. The public parameters (n, e) = (9379, 11) are shared. Encrypt Alice's key word, using 2-letter blocks. Please show work.
The operator of a Vigenere encryption machine is bored and encrypts a plaintext consisting of the same letter of the alphabet repeated several hundred times. The key is a seven-letter English word. Eve knows that the key is a word but does not yet know its length. What property of the ciphertext will make Eve suspect that the plaintext is one repeated letter and will allow her to guess that the key length is seven? What will the number of matches be for the different displacements?
Let the encryption keyword of a monoalphabetic cipher be ROME. (a) Show the encryption key in the table form. (b) Show the decryption key in the table form. (c) Obtain ciphertext for the following message sentence: Rome wasn’t built in a day.
Suppose your RSA public key is PK: {n, e} = {13861, 37}. Your friend sends you a ciphertext C = 9908. But unfortunately you have forgotten your private key, now you have to crack it yourself.a) Write down a possible condition of factors p and q.p= q=b) What is your private key SK: {d}?d=c) What is the plaintext of your friend’s message?The plaintext M =d) Suppose the plaintext M is a 12-digit number consisting of a prefix “19” and 1234567890. What is the corresponding ciphertext? Since M is greater than n, you only need to encrypt four digits at a time. Ignore redundant zeros. e.g., 0001 = 1. The result should contain three integers.The ciphertext C0 =
Alice and Bod have decided to use a symmetric encryption algorithm. They have some assumptions about their messages:- Messages only contain capital letters (i.e. A to Z)- The length of their shared key must be greater than or equal to the length of the plaintext- They assign each letter a number as follows: (A,0), (B,1), (C,2), (D,3),…, (Z,25)Their algorithm combines the key and the message using modular addition. The numerical values of corresponding message and key letters are added together, modulo 26. For example, if the plain text is “HELLO” and the key is “SECRET” then the encrypted message is calculated as following:Since the length of the plaintext is 5, we just need the first 5 letters of the key (i.e. “SECRE”), then for each letter, we should add corresponding letters in both the plaintext and the key modulo 26.Plaintext: H (7) E (4) L (11) L (11) O (14)Key: S (18) E (4) C (2) R (17) E(4)Cipher: Z (25) I (8) N(13) C(2) S (18) Write a program in Python, C/C++ or JavaScript to…
