Question

Alice wants to use the ElGamal digital signature scheme with public parameters p = 47, α = 2, secret value a = 7 and β = 34. She wants to sign the message M = 20 and send it to Bob. She chooses k = 5 as the secret value. Explain the procedure that Alice will use for computing the signature of the message. What information will she send Bob?

To solve the problem of signing the message \( M = 20 \) using the ElGamal digital signature scheme, Alice will follow these steps: ### Given Parameters: - Public parameters: \( p = 47 \), \( \alpha = 2 \) - Alice's secret key: \( a = 7 \) - Public key: \( \beta = 34 \) - Message to sign: \( M = 20 \) - Random secret value: \( k = 5 \) ### Step 1: Compute \( r \) The first part of the signature is \( r \), which _____ ___ _____ ______ __________ _________.

Decrypt each of the following cipher texts:

i) Text: "CBBGYAEBBFZCFEPXYAEBB", encrypted with affine cipher with key (7,2).

ii) Text:"KSTYZKESLNZUV", encrypted with Vigenère cipher with key "RESULT"

b) Another version of the columnar transposition cipher is the cipher using a key word. In this cipher, we encrypt as follows: Given a key word, we remove all the duplicate characters in the key word. For example, if the key word is 'SECRET", we remove the second 'E' and use 'SECRT" as the key word. To encrypt, we form a table as follows: In the first row, we write down the key word. In the following rows, we write the plaintext. Suppose we want to encrypt the text 'ATTACKATDAWN'. We make a table as follows:

S E C R T
A T T A C
K A T D A
W N X X X

Then we read off the columns in alphabetical order. We first read the column under 'C', followed by the columns under 'E', 'R', 'S' and 'T". We get the cipher text TTX TAN ADX AKW CAX. To decrypt, we reverse the process. Note that, since we know the length of the keyword, we can find the length of the columns by dividing the length of the message by the length of the keyword.
