Phrase: Feistel-like network | Statement: [Feistel network, variant, Feistel-like network]

Target entity: Feistel-like network
Context triple: [Feistel network, variant, Feistel-like network]

• A. Feistel network chosen
  A Feistel network is a symmetric structure for building block ciphers that splits data into halves and repeatedly applies round functions to achieve secure encryption and decryption.
• B. Substitution–permutation network
  A substitution–permutation network is a symmetric-key cryptographic design that secures data by repeatedly applying nonlinear substitutions and bitwise permutations to achieve confusion and diffusion.
• C. Serpent cipher
  Serpent cipher is a symmetric-key block cipher and former AES finalist known for its strong security margin and conservative design based on a substitution–permutation network structure.
• D. Lucifer cipher
  The Lucifer cipher is an early block cipher developed at IBM by Horst Feistel that served as a foundational design precursor to the Data Encryption Standard (DES).
• E. S-box
  An S-box (substitution box) is a fundamental nonlinear component in many block ciphers that maps input bits to output bits to provide confusion and resist cryptanalysis.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
