Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Feistel network | Statement: [RC2, cipherStructure, Feistel network]

Target entity: Feistel network
Context triple: [RC2, cipherStructure, Feistel network]

• A. 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.
• B. SDES
  SDES (Session Description Protocol Security Descriptions) is a key management mechanism used to negotiate and convey cryptographic parameters for securing media streams in real-time communication protocols.
• C. Rijndael
  Rijndael is a symmetric block cipher designed by Joan Daemen and Vincent Rijmen that was selected by NIST as the basis for the Advanced Encryption Standard (AES).
• D. Twofish
  Twofish is a symmetric key block cipher known for its speed, flexibility, and strong security, and was a finalist in the competition to become the Advanced Encryption Standard (AES).
• E. CBC-DES
  CBC-DES is a cryptographic privacy protocol that uses the Data Encryption Standard in Cipher Block Chaining mode to provide confidentiality for SNMPv3 messages.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Feistel network
Triple: [RC2, cipherStructure, Feistel network]

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.
