A novel optimization methodology for dynamic taint tracking based on just-in-time compilation is presented. First, the taint propagation logic is separated from the program logic precisely to simplifying the complexity of the taint propagation analysis. Then, a taint propagation framework is proposed and the correctness of the taint propagation analysis is proved. .Finally, redundan
