6. Alice designs a double-RSA cipher. She first generates two secret primes p and q, and compute n-p*q, then choose two public encryption exponents ei and e2 that are relatively prime to n). So becomes the public key. She tells people to encrypt message M by computing CFM el mod n and then C= C-2 mod n, finally sending just C to her. a. Show the decryption process (i.e., how Alice can obtain the plaintext M from the final ciphertext C) 6. Alice designs a double-RSA cipher.
