SecureMark TLS and wolfSSL

Ever wonder exactly how much power your crypto is consuming? How long the battery of your device will last after adding in security? wolfSSL has worked with EEMBC to plug wolfSSL into SecureMark TLS for benchmarking a hardware’s performance and power consumption (https://github.com/eembc/securemark-tls). One of the algorithms benchmarked with SecureMark is ECDSA which makes up the bulk of the power and time taken for TLS 1.3 and TLS 1.2 handshakes using ECDSA cipher suites. 

If you have interest in seeing how much power wolfSSL consumes on your device contact us at facts@wolfssl.com.

Excellent wolfBoot GitHub Fork

wolfSSL often recognizes the work of our amazing community through GitHub. Today, we’re giving visibility to the excellent work of Kasper Kyllönen and Dr. Ian Oliver, on their fork of the wolfBoot GitHub repository. Visit their fork and check out their changes here: https://github.com/nokia/wolfBoot

Their wolfBoot fork has some Raspberry Pi related improvements for testing, measured boot and debugging.

wolfBoot is a portable secure bootloader solution that offers firmware authentication and firmware update mechanisms. It can be easily ported and integrated in existing embedded software projects to provide a secure firmware update mechanism. Check out our GitHub page for our wolfBoot repository, as well as repositories of our other products!

Support for Android SQLCipher with wolfCrypt FIPS

We have added wolfCrypt support to SQLCipher, which enables encryption of a SQLite database. The port also supports using our wolfCrypt FIPS module.

SQLCipher extends the SQLite database library to add security enhancements that make it more suitable for encrypted local data storage like [1]:

  • on-the-fly encryption
  • tamper detection
  • memory sanitization
  • strong key derivation

This feature is enabled with `./configure –with-crypto-lib=wolfssl`.

See pull request https://github.com/sqlcipher/sqlcipher/pull/411 for details.

wolfTPM v2.3 Release Announcement

We are excited to announce our wolfTPM v2.3 release. This includes some minor fixes and features for PCR and GPIO.

If using a big endian platform consider updating to resolve a byte swapping issue with the TIS layer.

We have refactored the GPIO configuration example for use with either STM ST33 or Nuvoton NPCT750 TPM 2.0 modules.

The PCR example now includes a standalone read example.

Release Details:

  • Refactor GPIO support (single gpio_config) (PR #194)
  • Fix for Linux HAL IO try again timeout logic (PR #194)
  • Fix for big endian in TIS layer (PR #191)
  • Fix for RSAES padding (RSA_Encrypt) (PR #187)
  • Fix in tests to allow command code error for CreateLoaded (not supported on hardware) (PR #184)
  • Fix for compiler warning for file read in make_credential.c (PR #182)
  • Fixes for Windows builds (PR #181)
  • Fixes for RSA RNG in edge case builds (fixes wolfBoot build error) (PR #180)
  • Added PCR Read example (PR #185)

wolfSSL v5.0.0 Release

Happy Fall! wolfSSL has a great treat for all, we released version 5.0.0 and it is now ready for download! This includes a new major feature, having our FIPS 140-3 code added in. Stay tuned for more information in upcoming blog posts regarding the FIPS 140-3 code additions! It also includes notable feature additions such as the post quantum resistant code supporting use of liboqs, expansion to the compatibility layer for ease of replacing OpenSSL and many more features and fixes.

Key New Feature Additions

New Product

  • FIPS 140-3 — currently undergoing laboratory testing, code review and ultimately CMVP validation. Targeting the latest FIPS standard.
    • Federal Information Processing Standards (FIPS) 140-3 is a mandatory standard for the protection of sensitive or valuable data within Federal systems. FIPS 140-3 is an incremental advancement of FIPS 140-2, which now standardizes on the ISO 19790:2012 and ISO 24759:2017 specifications.

Post Quantum

  • Support for OQS‘s (liboqs version 0.7.0) implementation of NIST Round 3 KEMs as TLS 1.3 groups –with-liboqs
  • Hybridizing NIST ECC groups with the OQS groups
  • Remove legacy NTRU and QSH
  • Make quantum-safe groups available to the compatibility layer

Linux Kernel Module

  • Full support for FIPS 140-3, with in-kernel power on self test (POST) and conditional algorithm self test(s) (CAST)
  • –enable-linuxkm-pie — position-independent in-kernel wolfCrypt container, for FIPS
  • Vectorized x86 acceleration in PK algs (RSA, ECC, DH, DSA) and AES/AES-GCM
  • Vectorized x86 acceleration in interrupt handlers
  • Support for Linux-native module signatures
  • Complete SSL/TLS and Crypto API callable from other kernel module(s)
  • Support for LTS kernel lines: 3.16, 4.4, 4.9, 5.4, 5.10
  • KCAPI: add support for using libkcapi for crypto

Compatibility Layer Expansion

The release contained two vulnerabilities – one regarding a hang with DSA sign creation and the other regarding the handling of certificate name constraints. 
Vulnerabilities

  • [Low] Hang with DSA signature creation when a specific q value is used in a maliciously crafted key. If a DSA key with an invalid q value of either 1 or 0 was decoded and used for creating a signature, it would result in a hang in wolfSSL. Users that are creating signatures with DSA and are using keys supplied from an outside source are affected.
  • [Low] Issue with incorrectly validating a certificate that has multiple subject alternative names when given a name constraint. In the case where more than one subject alternative name is used in the certificate, previous versions of wolfSSL could incorrectly validate the certificate. Users verifying certificates with multiple alternative names and name constraints, are recommended to either use the certificate verify callback to check for this case or update the version of wolfSSL used. Thanks to Luiz Angelo Daros de Luca for the report.

wolfEngine and OpenSSL Provider Solution Now Public!

wolfSSL was developed with security and open source development in mind. As such we have continued to make sure our products are open source, so that they are free to download and modify under a GPL licence. 

We are so happy to announce that our product wolfEngine and our OpenSSL Provider solution with FIPS are now public under a GPL v.3 license! wolfEngine is a FIPS-certified crypto module (wolfCrypt) with OpenSSL as an OpenSSL engine. You may also know that OpenSSL 3.0 has done away with the engines paradigm in favor of a new concept, called providers. wolfSSL has developed an OpenSSL 3.0 provider, allowing you to use the latest version of OpenSSL backed by our FIPS-certified wolfCrypt library. Like wolfEngine, the wolfSSL provider for OpenSSL is an excellent pathway for users looking to get FIPS compliance fast while still using OpenSSL.

Check them out in our GitHub Repository here!

If you have any questions regarding wolfEngine, open source, or securing an embedded device, please contact us at support@wolfssl.com
