抄録

We propose a new (n, n) double block length hash function where collision and preimage security bound is respectively O(2^<tn>) and O(2^<2tn>). The strategic point of this scheme is able to handle short message tn (t < 1) bit, which is very significant issue for RFID tag security. It is known that the RFID tag needs to proceed short message but MDC-2, MDC-4, MJH are not properly suitable for meeting this criteria due to their constructions where these schemes can handle message size n bit (n = 128). Additionally the security bound of the proposed scheme is better than other (n, n) blockcipher based hash such as MDC-2, MDC-4, MJH and as well as obtaining higher efficient rate.
