Each letter (based on the position in the alphabet), a space (SP), and each punctuation mark was given a number from 1 (for A) to 30 (for the explanation mark) in the first blank row of the table. Each number in the first row was then increase by 61 (add 61 to each number for the next row of the table), and this answer was converted to its congruent number modulo 35 for the last row of the table. To decode…

The difficulty of breaking RSA algorithm depends on prime number factorisation c. DES algorithm is an example of stream cipher d. Symmetric ciphers are faster than asymmetric ciphers
We know that the size of the key in Data Encryption Standard (DES) is 64 bits, assume for padding we just add 0 atthe end of the plaintext (the original message), what is the result of padding for thefollowing text? At first replace the “YYY” with the first 3 letters of your name or familythen calculate the padding (show the result in hexadecimal format):“YYYComputerSecurity”

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 sets up an RSA public/private key, but instead of using two primes, she chooses three primes p, q, and r and she uses n=pqr as her RSA-style modulus. She chooses an encryption exponent e and calculates a decryption exponent d. Encryption and Decryption are defined: C ≡ me mod n and m ≡ Cd mod n where C is the ciphertext corresponding to the message m. Decryption: de ≡ 1 mod φ(n) | Let p = 5, q = 7, r = 3, e = 11, and the decryption exponent d = -13. n = 105 & φ(n) = 48 Q: Alice upgrades to three primes that are each 200 digits long. How many digits does n have?
