Stem algorithm is a robust static software watermarking scheme. It can resist many common attacks except collusive attacks. In this paper we propose an improved Stern algorithm, make it has the ability of resisting collusive attacks and simplify its implementation at the same time. Furthermore, we describe the implementation of our algorithm and the issues that arise when targeting MSIL. We then validated it by experiments against a variety of attacks.
