    Based on the compression function of the hash function standard SHA-256, SHACAL-2 is a 64-round block cipher with a 256-bit block size and a variable length key of up to 512 bits. In this paper, we present a related-key rectangle attack on 42-round SHACAL-2, which requires 2243.38 related-key chosen plaintexts and has a running time of 2488.37. This is the best currently known attack on SHACAL-2.
