Suite B Versus CNSA 1.0 Versus CNSA 2.0

With the CNSA (Commercial National Security Algorithm) 2.0 Suite coming into sharp focus recently, we thought we would talk about the history of how we got here and then focus on the differences between the various suites that came before it.

The first time the NSA came out with a suite of algorithms to be used to protect unclassified information was in 2005; it was called Suite B. The purpose was to specify algorithms that were approved so vendors knew what they needed to enable and disable in their protocols in order to provide security for the US federal government. It only allowed for AES, ECC and SHA2.

Later, in 2018 it was overridden by the CNSA 1.0 Suite which added in RSA and Diffie-Hellman but not DSA.

In 2022 CNSA 2.0 was announced, but interestingly, most of the algorithms it specified had not been standardized yet. For example, ML-DSA and ML-KEM have only just recently been standardized in 2024. The main focus of the 2.0 Suite is to ensure that vendors prioritize the transition to post-quantum algorithms.

Below is a chart of the algorithms that are specified for TLS and firmware/software signing use cases.

Use Case Suite B CNSA 1.0 CNSA 2.0
Firmware and Software Signing (i.e.: wolfBoot) N/A N/A LMS or XMSS; All parameter sets but without hyper-tree variants
TLS Key Establishment ECDH with P-256 or P-384 ECDH with P-384 or DH with 3072-bit modulus or RSA with 3072-bit modulus ML-KEM-1024 (FIPS-203)
TLS Authentication ECDSA with P-256 or P-384 ECDSA with P-384 or RSA with 3072-bit modulus ML-DSA-87 (FIPS-204)
TLS Symmetric Ciphers AES 128 or 256 in GCM mode AES 256 in GCM mode AES-256 in GCM mode
TLS Hash Algorithms SHA-256 or SHA-384 SHA-384 SHA-384

To our customers, know that wolfCrypt has implementations for all algorithms and parameter sets specified by Suite B, CNSA 1.0 and most notably CNSA 2.0. Please download the latest release of our wolfSSL source code archive at https://www.wolfssl.com/download/ and try it out.

The relevant configure time flags are:

  • –enable-lms
  • –enable-xmss
  • –enable-kyber
  • –enable-dilithium

All of them are specially implemented and optimized for maximum performance to run securely and with side-channel attack mitigations even on bare metal to satisfy secure boot use cases.

FIPS-Certified WireGuard: Bringing wolfCrypt into the VPN Solution

As WireGuard continues to grow in popularity for its simplicity and efficiency in VPN deployments, security-conscious organizations are increasingly demanding solutions that adhere to stringent security standards, such as the Federal Information Processing Standard (FIPS 140-3). FIPS certification is a key requirement for governmental agencies and industries like healthcare and finance, where secure cryptographic implementations are mandatory. However, WireGuard’s default cryptographic implementations, while highly secure, are not FIPS-certified.

This is where wolfCrypt steps in. wolfCrypt is a lightweight, portable, and highly optimized cryptographic library that offers FIPS 140-3 certification, making it an ideal partner for users seeking FIPS compliance in their WireGuard deployments. With our planned integration, we’ll replace the standard crypto suite that WireGuard offers (ChachaPoly, Curve25519, Blake2s) with our own certified algorithms (AES GCM, ECC P-256, SHA-256). One thing to note here is that FIPS-ified WireGuard end-points may only communicate with other FIPS-ified end-points. But this of course is not a bug, but a feature. FIPS can only talk to FIPS.

So by leveraging our incoming integration, users can gain access to a VPN solution that is both secure and FIPS-compliant. This is especially important for industries with strict security requirements. The performance of WireGuard, combined with the certified cryptographic operations of wolfCrypt, ensures that you don’t sacrifice speed or security. In fact, with wolfCrypt’s ability to utilize hardware acceleration for AES and SHA, you might end up with a much faster WireGuard. Additionally, wolfCrypt’s small footprint makes it a practical choice for deployments in constrained environments, including IoT devices, embedded systems, and edge computing setups. You get a robust, certified security layer without bogging down performance.

Are you interested in WireGuard with wolfCrypt?

Support for the Official Post-Quantum Standards ML-KEM and ML-DSA

Just a little while back to much fanfare, NIST-release these standards:

They are the post-quantum algorithms that are now standardized for use!! As a quick summary:

  • Kyber became ML-KEM (Module Lattice Key Encapsulation Mechanism) which is specified by NIST’s FIPS 203 document.
  • Dilithium became ML-DSA (Module Lattice Digital Signature Algorithm) which is specified by NIST’s FIPS 204 document.
  • SPHINCS+ became SLH-DSA (StateLess Hash-based Digital Signature Algorithm) which is specified by NIST’s FIPS 205 document.

ML-KEM and ML-DSA are great for general purpose use in protocols. For example, where you would use ECDH you would use ML-KEM and where you would use ECDSA you would use ML-DSA. SLH-DSA has specialized applications similar to those of LMS and XMSS. If you don’t want to deal with the statefulness of those algorithms, then SLH-DSA would be a great replacement.

Hot on the heels of this standardization announcement, we here at wolfSSL are announcing to the world that we have full implementation and support for ML-KEM and ML-DSA. You can have a look and try them out for yourself. Simply download the wolfSSL library, configure it to enable Dilithium and Kyber and run the benchmarks!

If you are interested in an implementation and support for SLH-DSA or have questions about any of the avobe, please contact us at facts@wolfSSL.com or +1 425 245 8247!

Post-Quantum wolfHSM on Aurix Tricore

The title says it all!! If you have been paying any attention at all to us here at wolfSSL, you will know that we are very proud of our wolfHSM product that already runs on the Aurix Tricore. What we have not been focusing on is the post-quantum algorithms that work with wolfHSM. Let’s use this blog post to fix that oversight.

In this post we will be focusing on ML-KEM, ML-DSA, and especially LMS and XMSS as they are all implemented in wolfCrypt and are therefore available in wolfHSM to protect you from the oncoming quantum threat.

First of all, ML-KEM is a Key Encapsulation Mechanism and generally used for key establishment. In most protocols this means it is used ephemerally, but because of the security properties inherent in the algorithm, it can also be used statically. That means it is fine for wolfHSM to generate an ML-KEM private key and use it multiple times under the protection of the HSM core.

Naturally, as MLDSA is a general purpose post-quantum signature scheme, wolfHSM has an opportunity to help just like in the case of ECDSA or RSA.

Now, where wolfHSM provides a unique offering is LMS and XMSS. These are stateful hash-based signature schemes which are great for firmware and software signing. That said, there is a state associated with the private key and that state MUST be properly managed. A consequence of improper management is that the key pair must be revoked and all signatures encountered after the point of revocation cannot be trusted.

Software libraries that implement signing by stateful hash-based signature schemes, such as wolfSSL, must trust the application developer to properly manage the state. In the case of wolfHSM, the wolfSSL team’s expertise can come into play to ensure proper management of the state. The application developer no longer needs to be an expert in post-quantum algorithms; simply a user of them.

If you’d like to learn how wolfHSM can support your post-quantum migration or have any questions, please contact us at facts@wolfSSL.com or +1 425 245 8247.
