wolfSSL provides many different products for many different implementations of internet protocols, one of which is wolfMQTT. The wolfMQTT library is a client implementation of MQTT written in C for embedded use, with support for SSL/TLS via the wolfSSL library, and also provides support for MQTT-Sensor Network (MQTT-SN). While wolfMQTT is based on the MQTT 3.1.1 specification, wolfMQTT also provides support for the MQTT v5.0 specification – which was recently approved and standardized by OASIS. This new standard comes with some changes, which are outlined below (from the MQTT v5.0 standard):

• Enhancements for scalability and large scale systems
• Improved error reporting
• Formalize common patterns including capability discovery and request response
• Extensibility mechanisms including user properties
• Performance improvements and support for small clients

wolfSSL’s embedded SSL/TLS library comes with support for many tools and libraries, one of which is curl! In addition to providing support and maintenance for curl, wolfSSL has also integrated the curl library in conjunction with Daniel Stenberg (an original author of curl and one of the founders). With this integration, wolfSSL now provides support and consulting for the curl library.

In addition, a modified version of the curl library, tiny-curl, is also available through wolfSSL. tiny-curl is a patch applied on top of curl to reduce its code size, which makes it favorable for embedded and real-time environments. Version 0.10 of tiny-curl is based on curl version 7.65.3, and is available for download from the wolfSSL download page: https://www.wolfssl.com/download/.

More information about wolfSSL and curl can be found on the curl product page: https://www.wolfssl.com/products/curl/. Details on wolfSSL support for curl and tiny-curl is also located on the support page here: https://www.wolfssl.com/products/support-packages/.

wolfSSL also provides support for the latest versions of the TLS protocol, including TLS 1.3! As such, wolfSSL is considering adding TLS 1.3 support to cURL in the future. More information about wolfSSL and TLS 1.3 can be found here: https://www.wolfssl.com/docs/tls13/.

wolfSSL is excited to add support for complete RTCA DO-178C level A certification! wolfSSL will offer DO-178 wolfCrypt as a commercial off -the-shelf (COTS) solution for connected avionics applications. Adherence to DO-178C level A will be supported through the first wolfCrypt COTS DO-178C certification kit release that includes traceable artifacts for the following encryption algorithms:

• SHA-256 for message digest
• AES for encryption and decryption
• RSA to sign and verify a message.
• Chacha20_poly1305 for authenticated encryption and decryption.

The primary goal of this initial release is to provide the proper cryptographic underpinnings for secure boot and secure firmware update in commercial and military avionics. wolfSSL brings trusted, military-grade security to connected commercial and military aircraft. Avionics developers now have a flexible, compact, economical, high-performance COTS solution for quickly delivering GIPS 140-2 validated crypto algorithms can be used in DO-178 mode for combined FIPS 140-2/DO-178 consumption. The wolfCrypt cryptography library FIPS 140-2 validation certificates can be applied to DO-178 uses. 

Optimization Support

We understand that securely rebooting avionic systems has rigorous performance requirements. As such, we’re here to help with cryptographic performance optimizations through our services organization.

As many people know, the OpenSSL project is struggling with FIPS, and their new FIPS release is not expected until December 2020. The version of OpenSSL that supports FIPS goes into End Of Life and is no longer supported in December of 2019.

This means that OpenSSL users will not have a supported package for over a year. This is a big issue for companies that rely on security.

To fill this breach, wolfSSL has integrated our FIPS certified crypto module with OpenSSL as an OpenSSL engine. This means that:

1. OpenSSL users can get a supported FIPS solution, with packages available up to the 24×7 level,

2. The new wolfCrypt FIPS solution also supports the TLS 1.3 algorithms, so your package can support TLS 1.3,

3. You can support hardware encryption with your package, as the new wolfCrypt solution has full hardware encryption support.

Additionally, should you be using one of the OpenSSL derivatives like BoringSSL, we can also support you.

If you have any questions or run into any issues, contact us at facts@wolfssl.com, or call us at +1 425 245 8247.

We love you.
