Message confidentiality and message integrity are two desirable properties for secure communication over the networks.

Following are the differences between message confidentiality and message integrity:

Message ConfidentialityMessage Integrity
The property that ensures that the attacker cannot understand the original plain text message even if he gains access to the encrypted message is called message confidentiality.The property that the receiver can determine whether a message is changed in the process of transmission is called message integrity.
Confidentiality ensures that only the sender and receiver can understand the original message.Integrity ensures that the original message is not changed in the process of transmission.
Encryption and decryption is used to achieve confidentiality.Check summing techniques are used to achieve integrity.
Encryption is applied on plain text.Check summing is applied on encrypted data.
