ISO/IEC 18033 specifies encryption systems (ciphers) for the purpose of data confidentiality.

ISO/IEC 18033-3:2005 specifies block ciphers. A block cipher is a symmetric encipherment system with the property that the encryption algorithm operates on a block of plaintext, i.e. a string of bits of a defined length, to yield a block of ciphertext.

ISO/IEC 18033-3:2005 specifies the following algorithms.

  • 64-bit block ciphers: TDEA, MISTY1, CAST-128.
  • 128-bit block ciphers: AES, Camellia, SEED.

NOTE The primary purpose of encryption (or encipherment) techniques is to protect the confidentiality of stored or transmitted data. An encryption algorithm is applied to data (often called plaintext or cleartext) to yield encrypted data (or ciphertext); this process is known as encryption. The encryption algorithm is designed so that the ciphertext yields no information about the plaintext except, perhaps, its length. Associated with every encryption algorithm is a corresponding decryption algorithm, which transforms ciphertext back into its original plaintext.
