semantic security
(I) An attribute of a encryption algorithm that is a formalization
of the notion that the algorithm not only hides the plaintext but
also reveals no partial information about the plaintext. Whatever
is efficiently computable about the plaintext when given the
ciphertext, is also efficiently computable without the ciphertext.
(See: indistinguishability.)
