WebFact:stream ciphers are insecure under CPA. –More generally: if E(k,m) always produces same ciphertext, then cipher is insecure under CPA. If secret key is to be used multiple times Þ given the same plaintext message twice, the encryption alg. must produce different outputs. Chal. Adv. k¬K m 0, m 1 ÎM c ¬E(k,m b) m 0ÎM c 0¬E(k, m 0 ...
