The Risks of 3DES in FIPS Certificates

When it comes to securing data, cryptographic algorithms are the backbone of many systems. 3DES (Triple Data Encryption Standard) was once a FIPS (Federal Information Processing Standards) algorithm but is no longer supported by NIST as of 1 Jan 2024 (over 1 year ago!) Having 3DES in a FIPS module today could spell trouble on the near horizon, not only for security but also for compliance.

Early Expiration of Certificates

A FIPS certificate comes with an expiration date, but the CMVP has the authority to move a certificate to the “historical list” before that date or to “Revoke” a certificate if a non-compliance issue is found. Either action makes the certificate no longer valid for new procurements or for use in certain scenarios if already deployed in the field. The CMVP exercised this authority during the transition from SP 800-56Arev[1,2] to SP 800-56Arev3, which tightened the standards for key establishment methods. Modules that did not meet the updated criteria by July of 2022 were moved to the historical list ahead of their expected expiration dates.

The same could happen with certificates that include 3DES now. Should the CMVP decide to enforce a hard transition on 3DES, any certificate with that algorithm could be revoked or made historical sooner than its listed expiration date. This means one could suddenly lose compliance, disrupting operations and requiring urgent updates to systems which can take many months or years to complete as anyone in the FIPS space is well aware.

An Example of Future-Proofing

An excellent example of future-proofing is the wolfSSL FIPS 140-3 module certificate #4718. Unlike many competing solutions, wolfSSL ensured that 3DES was not included in the boundary of this module. This proactive decision protects users of the wolfSSL Inc. wolfCrypt FIPS 140-3 module from the risks associated with 3DES and potential early certificate invalidation by the CMVP. By contrast, most of the competition did not do this future planning and still include 3DES in their boundary. This leaves users of those modules exposed to potential compliance issues and security risks.

What Should You Do?

  1. Avoid 3DES in New Designs: Choose FIPS modules that use stronger algorithms like AES. Ensure your vendors are aware of the risks and are providing compliant solutions.
  2. Audit Your Current Systems: If you’re already using a FIPS-certified module with 3DES, plan to migrate to a more secure alternative or re-validate that module without 3DES included in the boundary. Don’t wait for the CMVP to force your hand.
  3. Stay Informed: Keep an eye on updates from NIST and the CMVP. Understanding upcoming changes can help one with planning and preparing before CMVP decisions impact their systems.
  4. Test Your Transition Plans: Ensure that moving away from deprecated algorithms like 3DES won’t cause unexpected issues. Test thoroughly in a controlled environment.

Conclusion

3DES served its purpose in its time, but it is simply a liability now. If your systems rely on a FIPS certificate that includes 3DES, it’s time to act. By planning ahead and staying informed, you can ensure your systems remain secure and compliant, no matter what changes the CMVP enforces. Choosing solutions like wolfSSL’s FIPS 140-3 module, which proactively excludes outdated algorithms, can give you peace of mind and protect you from future disruptions.

Why Transition to DTLS 1.3 is Crucial for CNSA 2.0 Compliance and Cybersecurity

As we advance towards stronger cybersecurity measures, adhering to the latest security standards is crucial. Transitioning to DTLS 1.3 is becoming a necessity for anyone still using DTLS 1.2. Here are four compelling reasons why now is the perfect time to make the switch:

  1. Full Control over the Migration Process
    Typically, you control both the server and client, giving you complete control over the DTLS 1.3 migration. This flexibility allows for a smoother transition without disruption to your existing systems.
  2. Support for Post-Quantum Cryptography
    The upcoming enhancements to TLS and DTLS include support for ML-DSA (post-quantum authentication) and ML-KEM (key exchange algorithms), but these cryptographic advancements will only be available in TLS 1.3 and DTLS 1.3. Migrating now future-proofs your system against quantum threats.
  3. NSA’s CNSA 2.0 Guidance
    According to the NSA’s CNSA 2.0, these post-quantum algorithms should have already been implemented by 2024 in cloud services, with a mandate for their use by 2025. DTLS 1.3 is the only version that supports these algorithms, migrate now to ensure compliance with CNSA 2.0 standards.
  4. Competitive Advantage for Vendors
    If your software still uses DTLS 1.2 and is sold to government agencies in the U.S., transitioning to DTLS 1.3 is becoming urgent. This ensures your products meet the necessary security standards and helps you maintain a competitive edge in the market.

Plan your migration to DTLS 1.3 today. The migration to DTLS 1.3 isn’t just a technical upgrade. It is a strategic move to ensure CNSA 2.0 compliance and enhance your system’s security. Start planning your migration strategy today to stay ahead of future cryptographic challenges.

wolfSSL JNI/JSSE 1.15.0 Now Available

wolfSSL JNI/JSSE 1.15.0 is now available for download! This release contains a number of bug fixes and changes to the JNI and JSSE layers.

wolfSSL JNI/JSSE allows for easy use of the native wolfSSL SSL/TLS library from Java. The thin JNI wrapper can be used for direct JNI calls into native wolfSSL, or the JSSE provider (wolfJSSE) can be registered as a Java Security provider for seamless integration underneath the Java Security API. wolfSSL JNI/JSSE provides TLS 1.3 support and can also support running on top of the wolfCrypt FIPS 140-3 validated cryptography module.

Changes in this release are summarized below, but please see ChangeLog.md for a full list.

JSSE System/Security Property Support:

  • wolfssljni.debug – a new System property that enables JNI-level debug logging. This will add debug logs for the lower-level “com.wolfssl.*” classes that are part of the thin wolfSSL JNI wrapper. This is helpful for those users who are using the thin wolfSS JNI wrapper, or for JSSE-level users who need additional low-level debug logging support.

JSSE Changes:

  • Close the underlying Socket when SSLSocket startHandshake() fails before an exception is thrown and returned to the caller.
  • Fix a potential NullPointerException in SSLSocket Input/OutputStream that could happen in a threaded environment with some threads blocked in select()/poll().
  • Add support for SSLSession.getRequestedServerNames() to return the client’s SNI (Server Name Indication) request on the server side.
  • Add checks for legacy DHE keys for cipher suites using keys less than 1024 bits.
  • Optimize Java byte array creation in SSLEngine objects when receiving app data. This has a positive impact on performance by reducing garbage collector pressure.
  • Add the ability for SSLSocket.close() to interrupt read()/write() operations waiting in select()/poll(). This can speed up the return of threads blocked in read or write operations when the socket is closed, instead of waiting for the socket timeout to occur.

JNI Changes:

  • Always call wolfSSL_get1_session() inside WolfSSLSession.getSession() for more consistent native memory handling and cleanup.
  • Call wc_RunAllCast_fips() with wolfCrypt FIPS builds if available. This will run all FIPS Conditional Algorithm Self Tests (CAST) up front when the wolfJSSE provider is registered.
  • Add the ability to pass CFLAGS to java.sh (ie: CFLAGS=”-DTEST_DEFINE” ./java.sh)
  • Remove incorrect ATOMIC_USER preprocessor gate around native wolfSSL_GetSide() inside JNI glue code.

Example Changes:

  • Updates the example Android Studio project, defining WOLFSSL_CERT_REQ and WOLFSSL_CUSTOM_CONFIG. These defines are either not needed, or automatically set when building native wolfSSL on a Linux/Unix platform with “./configure –enable-jni”.

Testing Changes:

  • Add GitHub Actions PRB test for Maven (Linux, macOS) builds
  • Add JUnit tests for SSLSession state at various points throughout the handshake
  • Add GitHub Actions PRB test for native wolfSSL with NO_SESSION_CACHE_REF defined
  • Add GitHub Actions PRB test for WOLFJNI_USE_IO_SELECT

wolfSSL JNI/JSSE 1.15.0 can be downloaded from the wolfSSL download page, and an updated version of the wolfSSL JNI/JSSE User Manual can be found here. For any questions, or to get help using wolfSSL products in your projects, contact us at support@wolfSSL.com.

wolfCrypt JNI/JCE 1.8.0 Now Available

wolfCrypt JNI/JCE 1.8.0 is now available for download! This release contains a number of bug fixes, changes and new features to help better support usage from applications and 3rd party frameworks that consume wolfJCE internally.

wolfCrypt JNI/JCE allows for easy use of the native wolfCrypt cryptography library from Java. The thin JNI wrapper can be used for direct JNI calls into native wolfCrypt, or the JCE provider (wolfJCE) can be registered as a Java Security provider for seamless integration underneath the Java Cryptography API. wolfCrypt JNI/JCE can also support running on top of the wolfCrypt FIPS 140-3 validated cryptography module.

Changes in this release are summarized below, but please see ChangeLog.md for a full list.

New JCE Functionality:

  • Support for two new Java Security properties designed for use in edge cases where wolfJCE is being used with wolfCrypt FIPS 140-2/3 and the wolfJCE WKS KeyStore is replacing JKS and/or PKCS12 type KeyStore usage from applications for more complete FIPS compliance. Setting these properties to “true” will result in wolfJCE fake registering support for JKS and/or PKCS12 KeyStore support, but will automatically map it down to WKS KeyStore support internally. This can be helpful if using wolfJCE underneath Java code that hard-codes JKS/PKCS12 KeyStore types which cannot be changed, but the actual KeyStore files on disk can be updated to WKS type.
    • wolfjce.mapJKStoWKS
    • wolfjce.mapPKCS12toWKS

JNI and JCE Changes:

  • FIPS Conditional Algorithm Self Tests (CASTs) are now run once up front if wolfJCE is used with wolfCrypt FIPS 140-3, to prevent threaded app errors.

Example Changes:

  • Updated Android Studio example project CMakeLists.txt, defining WOLFSSL_CUSTOM_CONFIG
  • Addition of a JCE cryptography benchmark app (examples/provider/CryptoBenchmark.java). Basic AES-CBC/GCM benchmarks are in place now, but will be expanded to other algorithms in the near future.

Testing Changes:

  • Addition of GitHub Action testing for Maven (pom.xml) builds on macOS and Linux

TLS vs. SSH: When To Use Which

TLS and SSH are both widely used protocols used for creating secure connections between two systems over a secure network. But, they are designed for different use cases, so today we are going to take a quick dive into when you should use which.

About TLS

TLS (Transport Layer Security) is what is most commonly used to secure connections to the web, it is the successor to SSL (Secure Sockets Layer) to which wolfSSL gets part of its name. Today, almost all websites use TLS and most web browsers expect a website to use TLS when connecting. It has other use cases, such as email and VNC.

In general, TLS is designed so that a client can authenticate that the intended web server is where the data transfer is happening, and encrypt the data in transit.

About SSH

SSH (Secure SHell) is likely well known if you have used a Linux or Unix-based system before. It is typically used to remotely log into a server and execute commands on that server, as well as transfer files. It is ideal for remote shell or desktop access to machines over an unsecured network.

In addition to our namesake product, wolfSSL, we have a product called wolfSSH, which can provide lightweight SSH client and server support for embedded platforms.

Key Differences

Authentication

SSH allows for many different authentication methods, from basic passwords to keys and certificates. TLS typically relies on a trusted CA (Certificate Authority) for the authentication. Both TLS and SSH support OCSP for certificate revocation status.

Feature Set

SSH not only handles the basic authentication and encryption, but provides the next layer of features, such as shell access, file transfer and port forwarding. TLS is typically a secure wrapper around regular plain protocols.

Another feature SSH provides is the concept of channels. This allows multiplexing of multiple services over one SHH connection. For example, a single connection can have a shell, file transfer and multiple ports forwarded simultaneously.

Performance

TLS, particularly version 1.3, has a very low number of round trips required to handshake between the client and server. Whereas the handshake for SSH is a lot more involved, this can make a new connection a lot more expensive on a high-latency network.

Once the connection is established, the performance of each should be relatively similar, depending on the encryption algorithms used.

Ease Of Use

TLS is designed to be relatively easy to use, in particular, there is a low barrier to entry for the client user. SSH can be more difficult to configure and typically has more steps for the end user due to the mutual authentication.

Summary

Both TLS and SSH are essential parts of securing traffic over untrusted networks. TLS is very useful to wrap existing protocols with a layer of security, whereas SSH is ideal for remote command access to a system and network tunnels.

wolfSSL on STM32 MPUs

STMicroelectronics recently released a new range of ARM based MPUs. These are industrial grade ARM microprocessors that provide excellent performance as well as many useful features. ST have released OpenSTLinux to run on these chips, but they have also made a version of their bare-metal HAL API which works with these chips.

The wolfSSL team has recently ported wolfSSL to bare metal for the STM32MP135F in this range. This chip has a single-core 1GHz ARM Cortex-A7 which has hardware crypto acceleration features. There have been multiple parts to this work, which I will walk through in this post.

HAL porting

The previous AES, HASH and PKA HAL acceleration for STM32 MCUs has been ported to work with the STM32MP13 HAL. Every hardware acceleration feature we have previously supported for STM32 MCUs works with this MPU.

During testing, we clocked the MPU at 650MHz, which is the default high clock speed for bare-metal. At this speed we can get 12MB/sec AES-CBC, 9MB/sec AES-GCM and 90MB/sec SHA256. This is with the core clocked at only 65% of its maximum speed.

Extra hash support

We didn’t just stop there: we also added HAL acceleration for additional SHA types. With this MPU, we can now accelerate SHA-384, SHA-512 and SHA3 types. All also achieving around 85-90MB/sec. This is a 10-30x improvement over what you would typically see when running software-based algorithms for these types on the same hardware.

All the work we did to add these hash types should be easily portable to ST MCUs that support those types in the HAL. You can email us at support@wolfSSL.com if you wish for us to assist you with this porting work.

wolfSSL Example

Setting up and running the MPU in bare-metal mode can be a little bit tricky, so on top of all of this, we created a documented example so that you can create an echo client. This example is designed to be used with the STM32MP135F-DK development board. It uses FreeRTOS and LwIP, so it can be extended to do other things.

The example is available on our wolfssl-examples-stm32 GitHub repository.

There is also a README available in the main wolfSSL source tree, which can guide you through using wolfCrypt with the STM32MP135F.

What about Linux?

For those who want to use OpenSTLinux, wolfSSL “just works”. Using ST’s cross-compile toolchain, you can compile wolfSSL just like you would for any other Linux installation. On Linux, this is the wolfCrypt benchmark results:
