The lightweight block ciphers ULC and LICID are introduced by Sliman et al. (2021) and Omrani et al. (2019) respectively. These ciphers are based on substitution permutation network structure. ULC is designed using the ULM method to increase efficiency, memory usage, and security. On the other hand, LICID is specifically designed for image data. In the ULC paper, the authors have given a full-round differential characteristic with a probability of $2^{-80}$. In the LICID paper, the authors have presented an 8-round differential characteristic with a probability of $2^{-112.66}$. In this paper, we present the 15-round ULC and the 14-round LICID differential characteristics of probabilities $2^{-45}$ and $2^{-40}$ respectively using the MILP model.
