| Abstract(in English) | In this paper, we propose a 128-bit block cipher Camellia, with a key size 128 / 192 / 256-bits. Camellia is an 18-round Feistel cipher for 128-bit keys, and 24-round for 192 / 256-bit keys. In Camellia, the round function uses the SPN structure, and additional FL / FL^-1-functions are inserted every 6 rounds. To reduce hardware size, the key schedule 2-round Feistel structure with date randomizing part for generating intermediate keys. All subkeys are produced from the intermediate keys and the original secret key. We confirm that Camellia has enough security against differntial and linear cryptanalysis, in particular. Furboth any software environments and hardware implementations. Camellia achieves more than 300 Mbits / sec on Pentium III (800 MHz) using assembly language, and approximately 10 Kgates for hardware. |
