Abstract: | LUX is a new hash function submitted to NIST's SHA-3 competition. In this paper, we found some non-random properties of LUX due to the weakness of origin shift vector. We also give reduced blank round collision attack, free-start collision attack and free-start preimage attack on LUX-256. The two collision attacks are trivial. The free-start preimage attack has complexity of about 2^80 and requires negligible memory. |
