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 (CBC) mode | Statement: [NIST SP 800-38A, modeDefined, Cipher Block Chaining (CBC) mode]

Target entity: Cipher Block Chaining (CBC) mode
Context triple: [NIST SP 800-38A, modeDefined, Cipher Block Chaining (CBC) mode]

• A. 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.
• B. CBC-MAC
  CBC-MAC (Cipher Block Chaining Message Authentication Code) is a cryptographic technique that uses a block cipher in CBC mode to generate a fixed-size tag for ensuring data integrity and authenticity.
• C. AES-CTR
  AES-CTR is a widely used symmetric-key encryption mode that turns the AES block cipher into a fast, parallelizable stream cipher by encrypting successive counter values and XORing them with the plaintext.
• D. OCB authenticated-encryption mode
  OCB authenticated-encryption mode is a block cipher mode of operation that simultaneously provides data confidentiality and integrity with high efficiency and minimal overhead.
• E. 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.
• 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 (CBC) mode
Triple: [NIST SP 800-38A, modeDefined, Cipher Block Chaining (CBC) mode]

Cipher Block Chaining (CBC) mode is a block cipher operation method that enhances confidentiality by XORing each plaintext block with the previous ciphertext block before encryption, making each block’s encryption dependent on all preceding blocks.
