Overview#

Message Number is a process of number messages that are sent.

Message Number are a vital Cryptographic Primitive for several uses:

• provide a source for Initialization Vectors for the Encryption algorithm
• they allow Bob to reject replayed messages without the necessity of keeping a large database
• they tell Bob which messages were lost in transit
• they ensure that Bob receives the messages in their correct order.

For these reasons, the message numbers must increase monotonically (i.e., later messages have larger message numbers) and must be unique.
