List of Practical:
1. Implement RSA algorithm.
Take two prime numbers p,q
n=pxq
Initially take encryption key such that it is relatively prime with Ρ(n).
Find out decryption key.
Take plaintext message M, Ciphertext C=Me mod n.
To get plaintect from ciphertext M=Cd mod n.
Test case :
Two prime numbers 17,11
Encryption key = 7
Decryption key = 23
M=88
C=11
2. Implement playfair cipher. The plaintext is paired in two characters. Discuss the advantage of
polyalphabetic cipher over monoalphabetic cipher.
Key = MONARCHY
Plaintext = ar mu hs ea
Ciphertext = RM CM BP IM
3. Implement Ceasar and Hill cipher. Both are substitution cipher. Analyze the strength of the cipher in
terms of brute force attack and cryptanalysis attack. Suggest one way to improve and strengthen the cipher
and analyze with respect to cryptanalysis attack.
