| Abstract: | The 4-round ARIA differential property is given,and the differential enumeration attack on 7-round and 8-round ARIA-256 is presented in this paper.The attacks need 256 chosen plaintexts.The attack on 7-round ARIA has the time complexity of 2238.2 7-round ARIA encryptions in the preprocessing phase and 2124.2 7-round ARIA encryptions in the processing phase.The attack on 8-round ARIA has the time complexity of 2238 8-round ARIA encryptions in the preprocessing phase and 2253.6 8-round ARIA encryptions in the... |
