The Decision Linear (DLIN) assumption is a mathematical assumption used in elliptic curve cryptography[1]. In particular, the DLIN assumption is useful in settings where the decisional Diffie–Hellman assumption does not hold (as is often the case in pairing-based cryptography). The Decision Linear assumption was introduced by Boneh, Boyen, and Shacham [2].
Informally the DLIN assumption states that given , with random group elements and random exponents, it is hard to distinguish (for random ) from (for independently random ).
