Public-key encryption
... – assume that the attacker wants to decrypt c = me mod n intended for Alice – assume that Alice will decrypt arbitrary ciphertext for the attacker, except c – the attacker can select a random number r and submit c⋅re mod n to Alice for decryption – since (c⋅re)d ≡ cd⋅red ≡ m⋅r (mod n), the attacker ...
