- b.What is the maximum amount of time that it would take a computer that can test keys per second to carry out a brute-force attack on a file encrypted using 256-bit AES? Give your answer in seconds and years, using scientific notation, correct to 2 significant figures. You may assume a year is seconds and you may use a calculator to help work out the answer. Show all your working clearly in a way that will help your tutor understand how you arrived at your answer.Construct an experiment to estimate the speed at which a particular computer can process an authentication password. From that estimate, determine how long it would take to test common password candidate lists, such as a list of 100 or 1000 popular passwords, the same list enhanced with orthographic substitutions (3 for e, zero for O, one for l, 2 for z, and so forth), and a word list from a common online dictionary.The key to cracking a substitution cipher was first discovered by Arab scholars in the ninth century, but it was not widely known in the West until the fifteenth century. Once frequency analysis of ciphers became widespread, the plain substitution cipher became useless. To fix the problems in the substitution cipher, Blaise de Vigenère invented the strategy of using multiple letter mappings. Rather than using one key for the whole message, Vigenère’s idea was to use a different key for each letter of the message. Using a different key for each letter makes the frequency analysis much more difficult. The key to the Vigenère cipher is the Vigenère square. The rows shown here are simple rotations of the alphabet. Each row in the table shifts the letters of the alphabet one place to the left. When a letter shifts out of the first . The idea is to have the message we want to encode: secretmessage Alongside a word we will use to encrypt: encryptencrypt Plaint text s e c r…
- Write a script that inputs a line of encrypted text and a distance value and outputs plaintext using a Caesar cipher. The script should work for any printable characters. An example of the program input and output is shown below:Suppose we are using a method of encryption that does as much as possible to hide any patterns of a file, including symbol frequencies. And suppose we also want to compress the same file. In terms of the compression performance (the size of compressed file), is it better to compress the file before encrypting it, or encrypt the file before compressing it? Briefly explain the reasonExplain whether bit shiffting can be considered as a method to encrypt the file's content or to hide the file's content or both of them?
- a. Compute CBC-MAC for a message of 16 bits, “8642” (in Hexa). Assume a block size of 8 bits with an IV=F1 (in hexa). For simplicity, assume the encryption to be a simple XOR of the key with the plaintext. Let the encryption key be B4 (in Hexa). (Hint: Divide the message into blocks of 8 bits each; XOR each block with the previous cipher output; then encrypt this with the key. For the first block, XOR it with IV. Details in pages 325-326 Ch.12 of the textbook) b. Suppose Alice computes the Secret prefix MAC (page 322: secret prefix MAC(x) = h(key || x)) for the message ”AM” (in ASCII) with key “G” (in ASCII) that both Alice and Bob know. The hash function that is used is h(x1x2x3)= g(g(x1 XOR x2) XOR x3 ) where each xi is a character represented as 8 bits, and g(x) is a 8-bit string that is equal to the complement of bits in x. For example, g(10110011) = 01001100. The MAC is 8 bits. (8-bit ASCII representation of the characters is given below.) What is the Secret prefix MAC…The coded message that follows is an encrypted message from Brutus to the Roman Senate. It was produced using the Caesar cipher method, using a key-value of +5: OHWV GR MXOLXV RQ PRQGDB PDUFK 48 GUHVV: WRJD FDVXDO (EBRG) True FalseProblem with constructing MAC. The messages X to be authenticated consists of z independent blocks, so that: X = x1||x2|| . . . ||xz, where every xi consists of |xi| = 8 bits. The input blocks are consecutively put into the compression function ci = h(ci−1, xi) = ci−1⊕xi At the end, the MAC value: MACk(X) = cz+k mod 28 is calculated, where k is a 64-bit long shared key. Describe how exactly the (effective part of the) key k can be calculated with only one known message X.
- Check out the differences between cypher block chaining and cypher feedback mode for sending large files. Which ratio do you think works better?Encode the first 4 letters of your name by the symmetrical 2-stage feistel cipher, using the same cryptographic key, k, originated in the last non-null digit of your id in both stages. Function F will be a cyclic SHIFT LEFT of K positions. After obtaining the cipher, prepare the bit train for transmission and then decode it, proving the reciprocity of the process.
