  1. Camilla Encryption Algorithm“Use of the Camellia Encryption Algorithm in CMS” Akihiro KATO akato@po.ntts.co.jp NTT Software Corp. 19 NOV 2002

  2. Outline of Camellia • 128bit Block Cipher • Support same block/key sizes as AES • Royalty-free Licensing • Small hardware

  3. Content Encryption • Three different key sizes are identified by OID(s) • CBC mode only • Parameter field must have IV • Plain text padded before encrypt by number of appended octets

  4. Key Wrap • Identical to Section 2.2.1 ofRFC3394 (Key Wrap) with "AES" replaced by "Camellia" • OID Parameter field must be NULL
