The slide resynchronization attack on Grain was proposed in [6]. This attack finds related keys and initialization vectors of Grain that generate the 1-bit shifted keystream sequence. In this paper, we extend the attack proposed in [6] and propose related-key chosen IV attacks on Grain-v1 and Grain-128. The attack on Grain-v1 recovers the secret key with 2
