What algorithm is used to provide data integrity of a message through the use of a calculated hash value?

  • RSA
  • DH
  • AES
  • HMAC

Explanation: The IPsec framework uses various protocols and algorithms to provide data confidentiality, data integrity, authentication, and secure key exchange. To ensure that data is not intercepted and modified (data integrity), Hashed Message Authentication Code (HMAC) is used. AES is an encryption protocol and provides data confidentiality. DH (Diffie-Hellman) is an algorithm that is used for key exchange. RSA is an algorithm that is used for authentication.
