Abstract
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 22.59 chosen IVs, 2 26.29-bit keystream sequences and 2 22.90 computational complexity. To recover the secret key of Grain-128, our attack requires 2 26.59 chosen IVs, 2 31.39-bit keystream sequences and 2 27.01 computational complexity. These works are the first known key recovery attacks on Grain-v1 and Grain-128.
