View Answer

Answer: C,E

Explanation:

Cryptographic algorithms defined for use with IPsec include:

+ HMAC-SHA1/SHA2 for integrity protection and authenticity.

+ TripleDES-CBC for confidentiality

+ AES-CBC and AES-CTR for confidentiality.

+ AES-GCM and ChaCha20-Poly1305 providing confidentiality and authentication together efficiently.
