Message encryption can be done in two ways: In message encryption, the data is first converted to a ciphertext and then sent any further. A possible solution for this is to use message encryption. Message encryption: While sending data over the internet, there is always a risk of a Man in the middle(MITM) attack.These message authentication functions are divided into three classes: Higher-level: The lower level function is used here in order to help receivers verify the authenticity of messages.Lower level: At this level, there is a need for a function that produces an authenticator, which is the value that will further help in the authentication of a message.Message Authentication Functions:Īll message authentication and digital signature mechanisms are based on two functionality levels: Destination refusal: When the receiver of the message denies the reception.Source Refusal: When the source denies being the originator of a message.This way session tracking is also disrupted. Modification in the Timings: This includes replay and delay of messages sent between different parties.This includes insertion, deletion, and reordering of messages. Modification in the sequence: Changing the order of messages between parties.This includes inserting new information or deleting/changing the existing one. Modification in the Content: Changing the content of a message.

This will lead to mistrust between the parties communicating and may also cause loss of critical data.

Deception: Adding out of context messages from a fraudulent source into a communication network.

Analysis of Traffic: Determination of the pattern of traffic through the duration of connection and frequency of connections between different parties.

Revelation: It means releasing the content of the message to someone who does not have an appropriate cryptographic key.

Message authentication can be achieved using cryptographic methods which further make use of keys. This threat arises when the user does not have any information about the originator of the message. One of these attacks includes message authentication.
