In this paper, we analyze the block cipher SEED-192 which is an extended version of the ISO/IEC block cipher SEED. According to the result of this paper, there exist weak keys in 8 out of 20 rounds of SEED-192 against related-key differential attacks. This is the first cryptanalytic result for the key schedule of SEED-192.
