SHACAL-1 is an 80-round block cipher with a 160-bit block size and a key of up to 512 bits. In this paper, we present rectangle attacks on the first 51 rounds and a series of inner 52 rounds of SHACAL-1, and also present differential attacks on the first 49 rounds and a series of inner 55 rounds of SHACAL-1. These are the best currently known cryptanalytic results on SHACAL-1 in an one key attack scenario.doi:10.1007/11941378_3 fatcat:o6gf2pahznbwjb6wdi5m3krh4e
