Which two statements describe the characteristics of symmetric algorithms? (Choose two.)

Which two statements describe the characteristics of symmetric algorithms? (Choose two.)

  • They provide confidentiality, integrity, and availability.
  • They are commonly used with VPN traffic.
  • They use a pair of a public key and a private key.
  • They are referred to as a pre-shared key or secret key.
  • They are commonly implemented in the SSL and SSH protocols.
    Answers Explanation & Hints:

    Symmetric encryption algorithms use the same key (also called shared secret) to encrypt and decrypt the data. In contrast, asymmetric encryption algorithms use a pair of keys, one for encryption and another for decryption.
