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 Confidentiality||Message 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.|
