wolfSSL is happy to announce that we’ve recently added support for AES-SIV (synthetic initialization vector). Our implementation is based on the specification in RFC 5297. SIV mode is designed to be resistant to security degradation from accidental nonce reuse. Notably, AES-SIV is a mandatory AEAD algorithm for network time protocol (NTP) servers supporting network time security (NTS), per RFC 8915. We added AES-SIV to support our chrony 4.1 port, which is one of the only major NTP implementations that currently supports NTS.

Significant improvements to the C-only implementation of Single Precision math for P-256 and P-384 have been made in wolfSSL 5.1.1. Previously the Montgomery reduction implementation was performed generically. This function makes up a significant proportion of the time to perform ECC operations. By adding an optimised implementation the performance of the 32-bit C code improved by up to 80%! The 64-bit C code saw similar improvements.
Also the Aarch64 implementation of P-384 got an optimised version of the Montgomery reduction operation too. This improved its performance by up to 150%!
From fuzz testing, it was found that the implementation finding the square root modulo a prime (used in uncompressing a point) was not handling a value of zero correctly and resulted in the function not returning. This corner case will not occur with valid points. Compressed points are not recommended and disabled by default, but the fix was required to protect against potential attacks.
Bug fixes for the SP general math library were made for 5.1.1. These included fixes to sanity check values passed to sp_gcd (used in but not affecting RSA key generation) and better checking of maximum size of numbers when dividing. Also, when compiling for MIPS 32-bit, some compilers didn’t like the register names ‘$lo’ and ‘$hi’. These have been changed to ‘%lo’ and ‘%hi’ respectively.
The Single Precision code was also fixed around modular exponentiation. When the modulus is even or the exponent is 0 then we now error out. These are not use cases that are hit in normal operation.
A couple of bug fixes were made in the TFM implementation of our math library as well. An improved Montgomery reduction for Intel x86_64 was added in 5.0.0 and fixed to work reliably in this release. Also some out of memory error handling was improved around this same function.
A full list of what was changed can be found in the wolfSSL ChangeLog (https://www.wolfssl.com/docs/wolfssl-changelog/).

wolfSSL is adding 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:
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 enhanced, secure communications that can be readily certified to DO-178. In addition, any of the FIPS 140-2 validated crypto algorithms can be used in DO-178 mode for combined FIPS 140-2/DO-178 consumption. The wolfCrypt cryptography library has been FIPS 140-2 validated (Certificate’s #2425 and #3389). For additional information, contact us at fips@wolfssl.com!
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.

This is a quote from a message posted by Dustin Moody of NIST on the NIST PQC Forum at https://groups.google.com/a/list.nist.gov/g/pqc-forum/c/fvnhyQ25jUg :
“Yes - the 3rd round will shortly be ending. NIST is actively writing the 3rd Round report which will
explain our rationale for which algorithms we will standardize. We hope to be able to announce the
results and report not later than the end of March.”
Dustin Moody, Feb. 9, 2022
So, we can expect some news from NIST in a month or so. With this in mind, we thought this might also be a good time to talk about the FALCON Signature Scheme integration in the wolfSSL v5.1.1 release and some of the other work we have done around post-quantum cryptography.
The FALCON Signature Scheme is a post-quantum algorithm that is a finalist of round 3 of the NIST PQC competition. It shows much promise in that while its artifacts are large and key generation and signing are a bit slower than currently standardized algorithms, signature verification times are much faster which bodes well for IoT and constrained devices. You can compare the speed in our benchmarking data that can be found in Appendix G of our wolfSSL Manual: https://www.wolfssl.com/documentation/wolfSSL-Manual.pdf
The good news for our customers that want to experiment with FALCON is that it couldn’t be easier! All you need to do is build liboqs, rebuild wolfSSL and add the –with-liboqs flag. If you built your application to statically link with wolfSSL, you will need to rebuild your application. If you dynamically link, you do not need to rebuild. All you have to do now is swap out your certificates with FALCON certificates! No code changes are required for your application. You can find instructions and a script for generating a FALCON certificate chain here: https://github.com/wolfSSL/wolfssl-examples/tree/master/pq
For customers who want to see post-quantum algorithms working in a real world use-case, we have instructions for you to build a quantum-safe apache web server and curl web client. All you need to do is follow the instructions here: https://github.com/wolfSSL/osp/blob/master/apache-httpd/README_post_quantum.md
Finally, just a few words regarding motivation. Most people understand the harvest and decrypt threat model and thus see the urgency for moving to post-quantum key establishment. However, seeing the motivation for signature schemes might be harder. Suppose you are deploying authentication algorithms on devices that have long lifetimes and are hard to update. A good example of this might be firmware for industrial machinery or cars. If the lifetime of your deployment exceeds the time to a cryptographically relevant quantum computer, then you should probably consider experimenting to understand the impact of post-quantum algorithms sooner rather than later.
A full list of what was changed can be found in the wolfSSL ChangeLog (https://www.wolfssl.com/docs/wolfssl-changelog/).

wolfCrypt has been listed on the CMVP IUT List for FIPS 140-3! We are currently working with our testing lab to get validated as quickly as possible with the new FIPS standard from the NIST. wolfSSL is the first software library on the FIPS 140-3 IUT list for embedded development.
FIPS 140-3 involves a few significant changes, and wolfSSL is prepared to deliver the first and best implementation of FIPS 140-3.
FIPS 140-3 is the replacement for FIPS 140-2, so it is always a good idea to switch over to it as soon as possible. You will also want wolfSSL’s FIPS 140-3 Certificate for reasons including:
– Conditional Algorithm Self-Testing (CAST): Testing Streamlined – only test algorithms when they will be first used, or at will
– Addition of TLS v1.2 KDF (RFC7627) and v1.3 KDF (RFC8446)
– Addition of SSH KDF
– Addition of explicit testing of 3072-bit and 4096-bit RSA
– Addition of RSA-PSS
– Addition of HMAC with SHA-3
– Addition of AES-OFB mode
– Addition of external seeding source callback function for Hash_DRBG
– Removal of insecure algorithms: 3DES and MD5

Love it? Star wolfSSL on GitHub!
Last year was an excellent year for wolfSSL! We progressed on all of our critical performance vectors, including technical leadership, top notch support, sales growth and new design wins. The sheer volume of new code that we produced, in conjunction with our new products and design wins, is impressive to say the least. Additionally, we made the migration from a strictly on-prem based testing rig to a hybrid rig. Our new rig harnesses the power of cloud computing, and allows us to even further improve on our testing in order to bring you the best tested TLS. Thank you for reading, and please contact us if there is something that you would like on the wolfSSL roadmap for 2022!

Here at wolfSSL, we have been supporting your FIPS needs for several years now with our FIPS Ready, certificate #2425 and certificate #3389 source bundles. This support is going to continue with the soon to be granted FIPS 140-3 certificate. With the new certificate coming soon, we thought this might be a good time to do a bit of house cleaning.
As certificate #2425 has been added to the NIST sunset list as of June 2021, we will be removing the FIPS v1 feature from wolfSSL.
Customers who still need this feature are encouraged to move to the upcoming FIPS 140-3 certificate if timelines permit. However, if customers need a solution in the near term, they can move to certificate #3389 which sunsets in 2024.
