// Package simple includes simple schemes for functional encryption of
// inner products.
//
// All implementations in this package are based on the reference
// paper by Abdalla et. al (see https://eprint.iacr.org/2015/017.pdf).
// The reference scheme offers selective security under chosen-plaintext
// attacks (s-IND-CPA security).
//
// The reference scheme is public key, which means that no master secret
// key is required for the encryption.
//
// For instantiation from the decisional Diffie-Hellman assumption
// (DDH), see struct DDH (and its multi-input variant DDHMulti, which
// is a secret key scheme, because a part of the secret key is required
// for the encryption).
//
// For instantiation from learning with errors (LWE), see
// structs LWE and RingLWE.
