摘要：
Camellia is a 128-bit block cipher which has been selected as an international standard by ISO/IEC and a European encryption standard by the NESSIE project. Wu Wenling presented the collision attack on reduced-round Camellia in 2004, the 128-bit key of 6 rounds Camellia can be recovered with 2(10) chosen plaintexts and 2(15) encryptions. The improved collision attack on 6 rounds Camellia which based on four 4round distinguishers is presented in this paper. This attack requires less than 2(10.6) chosen plaintexts and 2(11.5) encryptions.
