متن کاملCryptanalysis of reduced versions of the Camellia block cipher
The Camellia block cipher has a 128-bit block length, a user key of 128, 192 or 256 bits long, and a total of 18 rounds for a 128-bit key and 24 rounds for a 192 or 256-bit key. It is a Japanese CRYPTRECrecommended e-government cipher, an European NESSIE selected cipher and an ISO international standard. In this paper, we describe a flaw in the approach used to choose plaintexts or ciphertexts ...
متن کاملAnalysis of Camellia
This report presents the results of a limited evaluation of the block cipher Camellia. We have found no important flaws nor weaknesses in Camellia. Camellia is an iterated cipher which runs in at least 18 rounds. The cipher has a simple and conservative design, which facilitates an easy analysis. It is relatively easy to be convinced about the resistance of Camellia with respect to differential...
متن کاملMeet-in-the-Middle Attack on Reduced Versions of the Camellia Block Cipher
The Camellia block cipher has a 128-bit block length and a user key of 128, 192 or 256 bits long, which employs a total of 18 rounds for a 128-bit key and 24 rounds for a 192 or 256-bit key. It is a Japanese CRYPTREC-recommended e-government cipher, a European NESSIE selected cipher, and an ISO international standard. In this paper, we describe a few 5 and 6-round properties of Camellia and fin...
متن کاملAnalysis of Camellia
Management Statement We have analysed Camellia and found no important weaknesses. The cipher has a conservative design and any practical attacks against Camellia would require a major breakthrough in the area of cryptanalysis of encryption systems. We think that Camellia is a very strong cipher, which matches the security of the best block ciphers today.
