Question
Chapter 8, Problem P14P
Program Plan Intro
Public Key:
The key that uses asymmetric-key encryption algorithms in public key encryption cryptography is known as public key.
OSPF routing protocol:
The OSPF or Open Shortest Path First is a routing protocol that uses a link state routing
Digital Signature:
Public-key primitives of message authentication are called digital signatures.
Given Information:
The OSPF routing protocol uses a MAC rather than digital signatures to provide message integrity.

Students have asked these similar questions
The OSPF routing protocol uses a MAC rather than digital signatures to provide message integrity. Why do you think a MAC was chosen over digital signatures?
Though DNS primarily uses UDP, however, it uses TCP in some places. There is
no automatic recovery if a DNS packet is missed. It's problematic if it does, how
can it be fixed?
TCP is a lightweight Transport-layer protocol that is used to communicate between applications. It lacks many of the same characteristics as UDP, such as dependability and flow control. is it true or false
