What are new in TLS 1.3 (Transport Layer Security)?

Introduction

It’s not new to everybody; TLS is extensively used the cryptographic protocol to render the end-to-end 100% secured communications across global online networks. For the successful prevention of tempering, forgery, counterfeit and eavesdropping of the web page and internet message, TLS 1.3 has brought a complete succeeding solution according to the latest IETF (Internet Engineering Task Force) standard.
If we think about both TLS and SSL, TLS is an affix security protocol that, notwithstanding more well-organized and effective than SSL. But also, it has some major drawbacks which are improved with the latest TLS 1.3 with 100% privacy and secured performance web interactions.

Incorporation of Crypto protocol

As TLS 1.0 was the successor SSL 3.0 (Secure Socket Layer) developed by Netscape, it was greatly accepted and recommended by PCI council. In spite of the target of keeping web interactions and transactions secured and private, many flaws were found which was broken by a malicious attack. Hence, TLS 1.3 came with an overhaul that empowers and streamlines the crypto protocol.

Significant Features of TLS 1.3

Find below some enhanced features of TLS 1.3 in comparison to SSL.

Powerful message authentication

TLS is more resourceful by possessing powerful message authentication, automatic key-material creation, and different encryption algorithms. For illustration, TLS allows pre-shared keys, secured isolated passwords, Kerberos and elliptical-curve keys which are not expected in SSL.  Even though both SSL and TLS are not interoperable, but TLS provides backward compatibility for old version devices that are still accommodating SSL.

Two layers TLS Protocol

As per protocol types TLS is further classified into two layers as follows

• TLS record protocol 
• TLS handshake protocol

The TLS record protocol ensures a secure connection, while the TLS handshake protocol enables server and client to authenticate each other with agreed encryption algorithms and cryptographic keys before any information exchange.

Client and Server security control

The TLS handshake protocol serves effective security control at the webserver and client to validate each other and to bargain security keys before any information is transferred. The TLS handshake is practically a multi-step procedure which includes the simple message sending, between server and client along with the keys exchange, a finish message, and cipher message.

VIRUS Attacks on TLS/SSL

BEAST: The BEAST (Browser Exploit Against SSL/TLS) has the capability of breaching of TLS/SSL security by extracting the unencrypted text in an encrypted session because of the weakness of TL S/SSL protocol in the CBC (cipher blocking chain)
CRIME: The crime (Compression Ratio Info-link Made Easy) is developed by the creators of BEAST developer, and contains nefarious use case which allows a hacker to capture or hijack the content of Website cookies from the browser during web sessions.
BREACH: The BREACH (Browser Reconnaissance and Exfiltration via Adaptive Compression of Hypertext), is developed on CRIME platform and concept which takes away e-mail ids, login tokens, and other c crucial information.
Heartbleed: Heartbleed enables hackers to hack private keys from the infected servers and anybody can read the information on this infected server.

TLS 1.3 resolves above virus attacks

TLS 1.3 is the first major IETF that comes with upgraded protocol and it diminishes all the flaws conducted by TLS 1.2 and successfully prevented above virus attacks. Find below some more features of TLS 1.3.

Faster encryption

TLS 1.3 has brought significant improvements in the sectors of security, speed of performance and privacy.  Because of the faster speed of HTTP-encryption, it’s considerably harder for illegal hackers to decrypt the traffic of HTTPS-encrypted information and hence better defend privacy.

Excellent monitoring tools

TLS 1.3 IETF has incurred huge improvements to set aside the protocol to function with valuable monitoring tools if integrated correctly. Furthermore, with security tightening, TLS 1.3 removes out few older algorithms that create risk and errors. These are RC4 Steam cipher, DES, RSA Key transport, 3DES, Diffie-Hellman groups, SHA-1 hashing, MD5, CBC Mode ciphers, and EXPORT ciphers, etc.
For instance, cryptographic hashes MD5 are no longer functioned, exact forward privacy is mandatory, and RC4 stream cipher is restricted. That’s why world-famous web browsers like Mozilla Firefox and Google Chrome use TLS 1.3 by default.
Excellent monitoring tools

0-RTT resumption

Also, the 0-RTT resumption function made by TLS 1.3 helps the client and server to keep in mind about their previous interaction or connection. Next time, the client and server can communicate instantly through previous keys used in past communications without any further security checking procedure.

Lighter weight

TLS 1.3 not only provides improved security service, and also it possesses lighter weight than its TLS 1.2 because of the fewer resources. Hence, it’s lighter to move faster in-network, faster encrypt, consumes fewer CPU resources and decreases latency, which leads to optimized performance.

Secured data integrity

TLS 1.3 provides the latest authentication, seclusion, and data integrity between two connected applications. It's the famous widely-installed security protocol incorporated today and is used for different web browsers and other web applications that need data to be firmly transformed over a network. For illustration, web browsing sessions, email sending, file transfers, VPN connections, remote desktop sessions, Skype chatting, and voice over IP (VoIP), etc.

Use of SHA-512

SHA-2 the Secure Hash Algorithm 2, is a set of cryptographic hash functions used for cryptocurrencies like Bitcoin. It could be able to work with some limited volume of data. SHA-512 handles a large volume of data.
In sum, TLS 1.3 has accompanied with all latest advanced security checking hash tools, lower resources, faster encryption, and all improved features in comparison to previous TLS and SSL versions. Now, every client asks to upgrade their website with TLS 1.3 certificate. What do you look for? Wanna new web application or need revamp your existing web application?
