The final version of TLS 1.3 (Transport Layer Security) just released by the IETF (from the Internet Engineering Task Force) and the popular ones browsers, like Chrome and 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 Appliances για ασφαλείς συναλλαγές στο Internet. Βασικά, όταν βλέπετε connection HTTPS you should know that it uses the TLS standard. Whether TLS 1.3 is already used (some beta version of it because the final version has just been released) or TLS 1.2 depends on the browser and the website 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 using Transport Layer Security 1.3. The Mozilla Foundation reports that about 5% of Firefox connections already use the TLS 1.3 standard, and that companies such as Google, the 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?
TLS 1.3 as we mentioned above is a major update that greatly improves speed and security. One of the key advantages of TLS 1.3 is that basic handshakes perform a single round-trip compared to the double round-trip of TLS 1.2. So the time required to connect to servers that support TLS 1.3 is reduced and websites that support TLS 1.3 load faster in preletterbrowsers that support the new standard.
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 that improves privacy while connecting to servers, as many of the information that was open with TLS 1.2 is now encrypted and non-readable during transport.
For those interested above, Cloudflare has published a technical overview of Transport Layer Security 1.3 on blog of the company.
