| English Abstract | 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 2119.8 chosen plaintexts, respectively. The corresponding time complexities are approximately 2167.1 11-round encryptions and 2220.87 12-round encryptions. As far as we know, our attacks are 216.9 times and 219.13 times faster than the previously best known ones but have slightly more data. © 2012 Elsevier Inc. All rights reserved. |
