Changes In wolfSSL for ARM Thumb-2 Builds

With wolfSSL release 5.7.4 we added the macro WOLFSSL_ARMASM_THUMB2. This macro can be defined to enable Thumb-2 ARM instruction optimizations and replaces the previous attempted autodetect on the macros __arm__ and __thumb__. Giving users complete control over which ARM assembly optimizations are compiled and used.

When building for Thumb-2 the source files beginning with thumb2-* should additionally be compiled in. If WOLFSSL_ARMASM_THUMB2 is not used then the armv8-32-* files will be used. These files are located in wolfcrypt/src/port/arm/.

The benefit of now having WOLFSSL_ARMASM_THUMB2 is that users can place all files in wolfcrypt/src/port/arm/ to be compiled and use the macro gate for selecting if the Thumb-2 section is optionally compiled or ARM32 implementation is. The armv8-32- code is very similar to the thumb2- code, but Thumb-2 is smaller in size.

wolfSSL Inc. announces Rock-solid curl: long term supported curl releases

Rock-Solid curl: long term supported curl releases

EDMONDS, Wash., Nov. 11, 2024 /PRNewswire-PRWeb/ — wolfSSL INC. (Headquarters: Edmonds, Washington, USA), a vendor specialized in cryptography and network security, announces Rock Solid curl long term supported curl releases. Each release branch will be supported for 5 years. Only security fixes and important stability bug fixes will be merged into the branches, no new features or surprises. Rock-solid curl is available exclusively to all existing support customers released under the same distribution model as normal curl, (or a commercial license). Rock-solid curl is meant to greatly reduce the risk of regressions and yet be a safe and secure solution with full support. For the companies who want this extra level of attention. An even smoother ride. The release schedule for Rock-solid curl release branches are roughly every 18-24 months.

Rock-solid curl 8.9.2 is the first long-term support curl version. As the version number implies, it is based on the curl 8.9.1 release that shipped in July, with two security fixes and a small number of stability patches applied. All current customers under contract will receive the release.

Daniel Stenberg, the original author of curl, has been part of the wolfSSL team since 2019 and will be the primary support for the Rock-solid curl project. Daniel will provide the releases, and most of the patching and the back-porting of what is deemed necessary. Nothing changes with or happens to the original curl project and the regular curl releases because of this, the curl license remains the same. The curl releases and the release cadence remain intact. Support customers help fund the project by allowing us to pay developers.

Downloads and all Rock-solid curl information is hosted on the dedicated rock-solid.curl.dev site, separate from the open source project on curl.se.

Switching to wolfCrypt’s Implementations of Post-Quantum Algorithms

Have you been trying out post-quantum algorithms in wolfSSL’s products? As you probably know, here at wolfSSL we have a step-wise approach to post-quantum algorithm integration:

  1. Define an API in wolfCrypt.
  2. Do an integration with an existing reference implementation (ie.: liboqs, PQM4, hash-sigs liblms, xmss-reference).
  3. Use these APIs in higher level libraries and products (ie.: wolfssl, wolfssh, wolfmqtt, wolfboot) to implement features.
  4. Invest the time and effort to write and optimize our own production grade implementation of the algorithm.

For LMS, XMSS, ML-KEM and ML-DSA the time has finally come to switch to using wolfSSL’s implementations of these algorithms. It’s very simple to do so. If you are using any of the following configure-time flags simply remove them from your configure command-line:

--with-liblms
--with-libxmms
--with-liboqs

Then ensure you are enabling the relevant algorithm that you are interested in. Relevant flags are:

--enable-xmss
--enable-lms
--enable-dilithium
--enable-kyber

Once this is done, you will be using our professionally optimized and tested implementations of post-quantum algorithms.

Do you need post quantum versions of Apache, NGINX, Lighttpd, cURL, or stunnel?

Our wolfSSL library has several post-quantum algorithms built in, but on their own, they aren’t always useful. How else can the PQC algorithms be used in production? Well, one of our areas of expertise is getting other open-source projects working with wolfSSL and then getting those integrations using post-quantum algorithms. We have post-quantum integrations with multiple web servers, a web client, and a secure tunneling solution. Read on to learn more!

For a more heavy-duty and reliable web server with professional production-ready code, we have a post-quantum integration with Apache.

For a lighter-weight yet fully featured and dependable alternative, you can turn to our post-quantum enabled Nginx integration.

Our wolfSSL library excels in constrained environments as does Lighttpd. For the most bare bones environments, our lighttpd post-quantum integration is likely the right choice.

And for the client side, we have also made the cURL web client quantum-safe! See this video for instructions on how to build.

If you’ve got an application where making changes is difficult due to legacy software, we’ve got our post-quantum integration with stunnel to make your migration a breeze.

Go ahead and try out these open source integrations! We are eager for your feedback, and happy to support your efforts Whether it be as part of a hackathon or as an experiment to understand feasibility or to gather benchmarking data, trying out these integrations is a great step in your plan for migration to post-quantum algorithms.

wolfBoot release: v.2.3.0

wolfBoot 2.3.0 has finally been released! The universal secure bootloader extends its support to new platforms, improves existing ports, and introduces new groundbreaking features that set the pace to defining secure-boot for the next generation of embedded systems.

A New Era of Secure Boot with ML-DSA and Hybrid Authentication

The introduction of quantum resistant algorithms in the latest releases of wolfSSL has accelerated the integration of asymmetric cryptography in our secure boot solution. In 2023, wolfBoot v2.0.0 expanded its signature verification algorithms to include the hash-based stateful signatures LMS (+HSS) and XMSS (^MT). wolfBoot v2.3.0 further extends these options by introducing ML-DSA, as specified in FIPS-204, for verifying the authenticity of firmware and other critical components. Support for ML-DSA in wolfBoot is currently available in three variants: ML-DSA-44, ML-DSA-65 and ML-DSA-87, corresponding to NIST security category 2, 3 and 5, respectively.

Hybrid Authentication: Post-Quantum Meets Classic Cryptography

One of the most anticipated features in WolfBoot 2.3.0 is its support for hybrid authentication, a method that combines Post-Quantum Cryptography (PQC) algorithms with traditional cryptographic techniques like ECC and RSA. This hybrid approach strengthens security by combining the resilience of PQC, which resists quantum attacks, with the well-established reliability of classic algorithms. Pairing PQC algorithms with ECC521 offers a path toward CNSA 2.0 compliance, a set of guidelines for systems demanding the highest levels of security.

Hybrid authentication in WolfBoot secures the boot process by signing and validating boot images with a combination of PQC and traditional cryptography. This dual-layer protection approach ensures that even if one algorithm becomes vulnerable, the other remains resilient, offering a future-proof strategy for embedded systems as quantum computing capabilities grow.

Boot time optimization and performance monitoring

Thanks to the newly introduced assembly optimization for ARM in wolfCrypt, image verification times have been dramatically reduced. These ARM optimizations are now enabled by default on all Cortex-M devices.
New benchmark tools have been added to our continuous integration environment, to ensure that we can constantly monitor boot time, footprint size, runtime memory usage and other performance indicators.

Improved keystore and keyvault management

Starting with wolfBoot 2.3.0, it is now possible to store public keys of different sizes in the same trust anchor. This is a crucial feature to allow double signature verification in hybrid mode, or when integrating heterogeneous components in the boot chain, involving more than one cipher at a time.

PKCS11 key vault storage drivers have also been improved, and can now reliably store keys in non-volatile memories, ensuring compatibility with wolfPKCS11.

Hardware support

In this version, the following new targets have been added to the list of hardware platforms we support:

  • Infineon AURIX TriCore TC3xx
  • Microchip AT-SAMA5D3
  • Nordic nRF5340

Moreover, the support for some of the existing ports has been improved and stabilized. During the development of wolfBoot v. 2.3.0 we mostly worked on the following targets:

  • NXP i.MX-RT family: the capabilities have been extended, including the support for built-in High-Assurance Boot (HAB) mechanism, provided by the manufacturer. Flash interaction has improved, and DCACHE invalidation has been fine-tuned to increase performance
  • Renesas RX: improvements introduced for this family of microcontrollers include the introduction of a full-flash erase operation, a more efficient flash management and support for boot-time IRQ.
  • Raspberry Pi: added UART driver
