4. (EAV-security) Let II = (Gen, Enc, Dec) be a secret key EAV-secure encryption scheme, with message space M = {0, 1}". We design the scheme II' = (Gen', Enc', Dec') as follows: • Gen' def Gen • Enc' (k, m): - t $ {0, 1}" - c← Enc(k,t) - - return (c, tm) • Dec' (k, ct) : - parse ct as (c, y) - a + Dec(k, c) return y Θα Prove that II' is EAV-secure.
