A Note on the Block Cipher Camellia
Camellia is a block cipher jointly developed by NTT and Mitsubishi in 2000. In this note, we describe some observations on the design of the cipher.
متن کاملCache Timing Attacks on Camellia Block Cipher
Camellia, as the final winner of 128-bit block cipher in NESSIE, is the most secure block cipher of the world. In 2003, Tsunoo proposed a Cache Attack using a timing of CPU cache, successfully recovered Camellia-128 key within 2 plaintexts and 35 minutes. In 2004, IKEDA YOSHITAKA made some further improvements on Tsunoo’s attacks, recovered Camellia-128 key within 2 plaintexts and 22 minutes. A...
متن کاملCamellia: A 128-Bit Block Cipher Suitable for Multiple Platforms
We present a new 128-bit block cipher called Camellia. Camellia supports 128-bit block size and 128-, 192-, and 256-bit keys, i.e. the same interface specifications as the Advanced Encryption Standard (AES). Efficiency on both software and hardware platforms is a remarkable characteristic of Camellia in addition to its high level of security. It is confirmed that Camellia provides strong securi...
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 ...
