The correct answer is conventional encryption

Key Points

  • Conventional encryption is another term for symmetric encryption.
  • In symmetric encryption, the same key is used for both encryption and decryption of data.
  • This method is known for being fast and efficient, making it suitable for encrypting large amounts of data.
  • However, it requires secure key management to ensure that the encryption key is not compromised.
  • Examples of symmetric encryption algorithms include AES (Advanced Encryption Standard), DES (Data Encryption Standard), and 3DES (Triple DES).

Additional Information

  • Public-key encryption (Option 1) is another term for asymmetric encryption, where different keys are used for encryption and decryption.
  • Asymmetric encryption (Option 2) involves a pair of keys: a public key for encryption and a private key for decryption.
  • Hybrid encryption (Option 4) combines both symmetric and asymmetric encryption techniques to leverage the advantages of each.
  • Symmetric encryption is generally faster than asymmetric encryption but requires secure key distribution and management.
