摘要	As an international standard adopted by ISO/IEC, the block cipher Camellia has been used in various cryptographic applications. In this paper, we reevaluate the security of Camellia against impossible differential cryptanalysis. Specifically, we propose several 7-round impossible differentials with the FL/FL^-1 layer. Based on one of them, we mount impossible differential attacks on 11-round Camellia-192 and 12-round Camellia-256. The data complexities of our attacks on 11-round Camellia-192 and 12-round Camellia-256 are about 2¹²⁰ chosen plaintexts and 2^119.8 chosen plaintexts, respectively. The corresponding time complexities are approximately 2^167.1 11-round encryptions and 2^220.87 12-round encryptions. As far as we know, our attacks are 2^16.9 times and 2^19.13 times faster than the previously best known ones but have slightly more data. © 2012 Elsevier Inc. All rights reserved.
