Digital Signature (5-5): In the course notes we looked at RSA for encryption and signatures (using exactly the same mathematical formula), and ElGamal for encryption. There has been several questions on using ElGamal for signature. The ElGamal encryption algorithm cannot be used for signatures but there are signature schemes that is based on discrete logarithm. (a) Search for simple explanation of the ElGamal signature scheme and DSA signature scheme (Hint: Wikipedia). Can these algorithms be used to encrypt a message?...

If Bob has a private key XB = 27, find his public key YB. c. What is the shared secret key between Alice and Bob? Question2: Alice and Bob use the Diffie-Hellman key exchange technique with a common...
Write a program in Python implement the RSA algorithm for cryptography. Set up: 1.Choose two large primes, p and q. (There are a number of sites on-line where you can find large primes.) 2.Compute n = p * q, and Φ = (p-1)(q-1). 3.Select an integer e, with 1 < e < Φ , gcd(e, Φ) = 1. 4.Compute the integer d, 1 < d < Φ such that ed ≡ 1 (mod Φ). The numbers e and d are...

8.17. Considering the four examples from Problem 8.13, we see that the Elgamal scheme is nondeterministic: A given plaintext x has many valid ciphertexts, e.g., both x=33 and x=248 have the same ciphertext in the problem above. 1. Why is the Elgamal signature scheme nondeterministic? 2. How many valid ciphertexts exist for each message x (general expression)? How many are there for the system in Problem 8.13 (numerical answer)? 3. IstheRSA crypto systemnondeterministic once the public key has been chosen?...
