The final version of TLS 1.3 (Transport Layer Security) just released by the IETF (από το Internet Engineering Task Force) και οι δημοφιλείς browsers, όπως ο Chrome και ο Firefox, already support the new security standard.
TLS 1.3 is a very significant update to TLS 1.2 despite the minor change in version number. The Layer Security Transport standard is used by devices for secure Internet transactions. Basically, when you see connection HTTPS θα πρέπει να γνωρίζετε ότι χρησιμοποιεί το πρότυπο ΤLS. Το εάν χρησιμοποιείται ήδη το TLS 1.3 (κάποια beta έκδοσή του γιατί η final έκδοση κυκλοφόρησε μόλις) ή το ΤLS 1.2 εξαρτάται από το πρόγραμμα περιήγησης αλλά και την by clicking here you are visiting.
Many beta versions of TLS 1.3 have been released in recent years as the new security standard is being developed. Mozilla and Google's browser development teams have started to support the new template since its development was still in the experimental stages.
So there are already some websites that use Transport Layer Security 1.3. The Mozilla Foundation reports that around 5% of Firefox connections already use the TLS 1.3 standard, and that companies such as Google, Facebook or Cloudflare already support TLS 1.3. We should mention that iGuRu.gr also supports connections with TLS 1.3.
What makes TLS 1.3 (Transport Layer Security) different?
The TLS 1.3 as mentioned above is an important update that greatly improves speed and security. One of the main advantages of TLS 1.3 is that basic handshakes perform a single round-trip compared to TLS 1.2's double round trip. So the time it takes to connect to servers that support TLS 1.3 is reduced and websites that support TLS 1.3 are loading faster on browsers that support the new template.
Security has also been improved in Transport Layer Security 1.3 compared to previous versions. TLS 1.3 focuses on a few well-known encryption algorithms, while TLS 1.2 may include support for more algorithms, but some of them have been compromised in the past.
TLS 1.3 encrypts most of the handshake which improves privacy when connecting to servers, as many of the information that were open with TLS 1.2 are now encrypted and unreadable in transit.
For those interested above, Cloudflare has published a technical overview of Transport Layer Security 1.3 on blog of the company.
