Advanced Encryption Standard

Target entity: Advanced Encryption Standard
Context triple: [Wi‑Fi Protected Access, encryptionMethod, Advanced Encryption Standard]

• A. 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.
• B. Diffie–Hellman key exchange
  Diffie–Hellman key exchange is a foundational cryptographic protocol that enables two parties to securely establish a shared secret over an insecure communication channel.
• C. New Directions in Cryptography
  New Directions in Cryptography is a landmark 1976 paper that introduced the concepts of public-key cryptography and digital signatures, fundamentally reshaping modern cryptography and secure communications.
• D. RSA
  RSA is a widely used public-key cryptographic algorithm that enables secure key exchange and digital signatures in many internet security protocols.
• E. ChaCha20
  ChaCha20 is a modern stream cipher designed by Daniel J. Bernstein, widely used for its high performance and strong security in protocols like TLS.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
