(ElGamal encryption): show how, given an encrypted message C1=E(m), it is possible to create a different encrypted copy that will be decrypted to the same message without knowing the key that was used for the encryption.

meaning, create C2 so that D(C2)=m

Given the prime factors p and q, the encryption exponent e, and the ciphertext C, apply the RSA algorithm to find (a) the decryption exponent d and (b) the plaintext message M. p q e C 17 5 19 65 I have to get d and M

Assume p = 13, q = 7, e = 11 and message m = 46. 1)...

Assume p = 13, q = 7, e = 11 and message m = 46. 1) Can given e be suitable for public key? Give reason why. 2) Find d = e-1 if e is suitable. 3) Perform encryption on the message m using RSA algorithm. 4)Perform decryption on the ciphertext c = 56 using the RSA algorithm. 5) is c = 56, the ciphertext for the message m = 46?
