In this paper, we present a rigorous evaluation of Thing and Ying's attack (TY attack) [11] along with practical implementations. We find that the cryptanalysis time of their attack is too high to be practical. We also propose a more general time memory trade-off by combining the distinguished points strategy with TY attack. Both theoretical analysis and experimental results show that our new design can save about 53.7% cryptanalysis time compared to TY attack and can reduce about 35.2% storage requirement compared to the original rainbow attack.
