TLS 1.3 combined with FIPS (#FIPS #TLS13)

For 2018, it's predicted that there will be more than 31 billion connectable IoT devices across the world. To put that number into perspective, imagine if every square mile on the Earth's surface was monitored by more than 150 IoT devices each. If this were square kilometers, there would be more than 60 IoT devices per square kilometer. With 31 billion devices potentially contributing to global internet traffic, this reveals a glaring need for an efficient and powerful way to secure data - and wolfSSL is the perfect solution.

wolfSSL is a lightweight TLS/SSL library that is targeted for embedded devices and systems. It has support for the most recent draft of the TLS 1.3 protocol, which is a secure protocol for transporting data between devices and across the internet. In addition, wolfSSL uses the wolfCrypt encryption library to handle its data encryption. Because there is a FIPS 140-2 validated version of wolfCrypt, this means that wolfSSL not only has support for the most current version of TLS, but it also has the encryption backbone to secure your data. FIPS 140-2 is a government certification that certifies that an encryption module has successfully passed rigorous testing and meets high encryption standards as specified by NIST.

Currently, wolfSSL is theĀ only implementation of the TLS protocol that can support both the most recent version of TLS 1.3 and is FIPS 140-2 validated.

Some key benefits of combining TLS 1.3 with FIPS validated software include:

  1. Software becomes marketable to federal agencies - without FIPS, a federal agency is not able to use cryptographic-based software
  2. Single round trip
  3. 0-RTT (a mode that enable zero round trip time)
  4. After Server Hello, all handshake messages are encrypted.

And much more! For more information regarding the benefits of using TLS 1.3 or using the FIPS validated version of wolfCrypt, check out wolfSSL's TLS 1.3 Protocol Support and our wolfCrypt FIPS page.
