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: Cipher Block Chaining | Statement: [CBC-DES, usesModeOfOperation, Cipher Block Chaining]

Target entity: Cipher Block Chaining
Context triple: [CBC-DES, usesModeOfOperation, Cipher Block Chaining]

• A. 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.
• B. 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.
• C. 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.
• D. 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.
• E. RC4 stream cipher
  The RC4 stream cipher is a once-widely used symmetric key algorithm known for its simplicity and speed in software, but now considered insecure due to multiple discovered vulnerabilities.
• 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: Cipher Block Chaining
Triple: [CBC-DES, usesModeOfOperation, Cipher Block Chaining]
