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.

wolfSSH with X.509 Certificates

Did you know wolfSSH can use X.509 certificates in place of SSH public keys? wolfSSH supports RFC 6187, “X.509v3 Certificates for Secure Shell Authentication”. This uses wolfSSL’s certificate management for TLS, so the certificates may be checked against CRLs and OCSP.

wolfSSH has been used in applications as a server where it needed to validate some FPKI (Federal Public Key Infrastructure) profiles. It is used with clients that authenticate the user’s credentials accessed via a card reader. wolfSSH’s client can be given an X.509 certificate to authenticate the user with the server.

FIPS vs FedRAMP Compliance and Requirements

The wolfSSL team has noticed an uptick in questions about FedRAMP requirements. Today, we want to cover the differences between FIPS and FedRAMP.

FIPS:

The Federal Information Processing Standards (FIPS) stipulate security requirements for cryptographic modules, which wolfSSL Inc. meets with our wolfCrypt FIPS module. NIST and the CMVP then encourage all federal programs using cryptography to follow these standards. Federal Procurement Officers (at the urging of NIST and the CMVP) then require FIPS compliance for solutions that consume cryptography and are used within the scope of their federal program(s).

FEDRAMP:

The Federal Risk and Authorization Management Program (FedRAMP) focuses on the security assessment, authorization, and continuous monitoring of cloud products and services. A prerequisite for FedRAMP is the proper implementation of a FIPS-validated cryptographic module by the cloud service provider.

Both programs aim to enhance data security but differ in scope. While FIPS focuses on cryptographic module validation and cryptography, FedRAMP ensures the overall security of cloud services, one part of which is proper implementation of FIPS validated cryptography for all cryptography running in the cloud. Beyond checking for proper FIPS implementations, FedRAMP also ensures the cloud service provider is fully compliant with NIST SP 800-53 IE: Security Controls, a NIST Risk Management Framework (RMF), service is monitored continuously, data protection methods are robust, incidents can be detected, responded to and recovered from, and more. For a complete list please refer to SP 800-53 at this [LINK].

To support wolfSSL customers, wolfSSL Inc. offers a service to fully validate any Operational Environment (OE) (IoT, embedded, FPGA, Digital Signal Processor (DSP), laptop, desktop, server blade, or cloud system). wolfSSL Inc (the vendor) will fully test and validate the OE of choice using a third-party NVLAP accredited FIPS lab (or CSTL) and get the OE listed as a CMVP-validated OE on the wolfCrypt FIPS Certificate. This is a CMVP-backed OE addition which is guaranteed to be acceptable by any federal program with a FIPS requirement, as opposed to vendor affirmation or user affirmation which often fall short of the mark. Additionally, once the primary certificate is updated with the OE of choice, a rebranded cert with the customer’s logo and letterhead can be offered including that new OE.

wolfSSL’s wolfCrypt FIPS module supports the latest FIPS 140-3 standards and holds the world’s first SP800-140Br1 FIPS 140-3 validated certificate (#4718). Our expert support team is available to assist with the proper implementation of the module on your target OE, a critical step for achieving a successful FedRAMP effort.

Beyond getting proper OE’s for FEDRAMP initiatives, wolfSSL can support customers that are either:

  1. Using an alternative OS within AWS, Azure, or Oracle cloud, or,
  2. If you are standing up your own cloud, support you with meeting the FedRAMP FIPS requirements for the operating system of your choice.

Strengthening RSA default minimum to 2048 bits

wolfSSL helps make the internet secure. Part of this task is continually updating our default settings to keep up with adversarial advancements. A recent article detailed the use of default RSA key sizes by an IoT manufacturer, which resulted in a 512 bit key being used for authentication. “The factoring required $70 in cloud computing costs and less than 24 hours.”

Since wolfSSL also had the default minimum set to 512 bits, we decided to update the default minimum to 2048 bits. The decision to use 2048 bit for the minimum was based on NIST recommendations and security industry best practices. This affects key generation using wc_MakeRsaKey. Testing infrastructure was also updated to be sure the smaller key sizes are still being covered by CI tests. The default RSA key size minimum can be overridden in the configuration using the RSA_MIN_SIZE macro.
