Applied cryptography and network security : first International Conference, ACNS 2003, Kunming, China, October 16-19, 2003 : proceedings / Jianying Zhou, Moti Yung, Yongfei Han, (eds.).In this paper, we make progress on χ^2-attack by introducing the optimization. We propose three key recovery attacks against RC6 without post-whitening, and apply these three key recovery algorithms to RC6. We discuss their differences and optimization and thus our best attack can break 16-round RC6 without pre-whitening with 128-bit key (resp. 16-round RC6 with 192-bit key) by using 2^<117.84> (resp. 2^<122.84>) chosen plaintexts with a success probability of 95% (resp. 90%). As far as the authors know, this is the best result of attacks to RC6.
