Let us start with the last lecture of fundamental cyber cybersecurity model, and that is the transport
layer security.
In this lecture, you will learn to describe the transport security protocol and the tireless handshaking
protocol.
Let us get started.
What is transport layer security?
That is peerless.
Beardless is a cryptographic protocol that provides end to end communications security on networks and
is widely used for Internet communications and online transactions.
It is an IETF standard intended to prevent eavesdropping, tampering and message forgery.
Common applications that employ tearless include web browsers, instant messaging, applications, emails
and voice over Internet protocol.
Many businesses used to secure all the communications between the Web servers and browsers, regardless
of whether sensitive data is being transmitted.
Beardless Predecessors', that is the secure soccer player, was developed by Netscape in 1995.
Now the obvious question is what is the difference between tearless and unnecessary?
Fearless is more efficient and more secure than SSL as it has a stronger message authentication, key
material generation and other encryption algorithms.
For example, Dialis support pre keys, secure remote passwords, elliptical keys and cabarrus that
as SSL does not.
Businesses are not interoperable, but the U.S. does offer backward compatibility for older devices
still using a system.
The is protocol specification defines two layers, there'd be electrical protocol, provides connection,
security and peerless handshake protocol enables the client and so to authenticate each other and negotiate
security keys before any data is transmitted.
So this is the peerless handshaking protocol.
The peerless handshake is a multi-step process.
A basic loose handshake involves the client and the server sending hello messages and the exchange of
keys, cipher message and a finished message.
Let's get started here.
So the client since hello the server replies hello certificate plus done client replies client key exchange
plus change siple specification and then client is finished.
Then server replies OK, change cyper specifications changed and Silva replies finish.
Now the handshake protocol is being established.
A secure connection is being established between client and server and then the transfer of data begins.
So the server checks what the highest SSL or Peeler's version is that being supported by both of them?
This certificate must be trusted either by the client itself or a party that the client trust.
We have seen about these certificates in previous videos.
