The ciphertext must be indistinguishable from true random values.
Enumerating all possible keys must be infeasible.
Produce plaintext from ciphertext without the key
There should be no way short of enumerating all possible keys to ﬁnd the key from any reasonable amount of ciphertext and plaintext, nor any way to produce plaintext from ciphertext without the key.
