  "term": "Forward Cipher Function",
  "field": "Cybersecurity",
  "definition": "1. One of the two functions of the block cipher algorithm that is selected by the cryptographic key.\n\n2. A permutation on blocks that is determined by the choice of a key for a given block cipher.\n\n3. One of the two functions of the block cipher algorithm that is determined by the choice of a cryptographic key.\n\n4. The permutation of blocks that is determined by the choice of a block cipher and a key.\n\n5. One of the two functions of the block cipher algorithm that is determined by the choice of a cryptographic key. The term “forward cipher operation” is used for TDEA, while the term “forward transformation” is used for DEA.",
