AES-GCM

Target entity: AES-GCM
Context triple: [IEEE 802.1AE, uses, AES-GCM]

• A. 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.
• B. Advanced Encryption Standard
  Advanced Encryption Standard is a widely used symmetric block cipher standard that secures digital data in applications ranging from wireless networks to government communications.
• C. 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.
• D. 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.
• E. IEEE 802.1AE MACsec standard
  The IEEE 802.1AE MACsec standard is a network security protocol that provides data confidentiality, integrity, and origin authenticity for Ethernet traffic at the media access control (MAC) layer.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
