liboqs version 0.9.1-rc1

About

The Open Quantum Safe (OQS) project has the goal of developing and prototyping quantum-resistant cryptography. More information on OQS can be found on our website: https://openquantumsafe.org/ and on Github at https://github.com/open-quantum-safe/.

liboqs is an open source C library for quantum-resistant cryptographic algorithms. Details about liboqs can be found in README.md. See in particular limitations on intended use.

liboqs can be used with the following Open Quantum Safe application integrations:

  • oqs-provider: A standalone prototype OpenSSL 3 provider enabling liboqs-based quantum-safe and hybrid key authentication and exchange for TLS 1.3, X.509 certificate generation and CMS operations.
  • OQS-BoringSSL: A prototype integration of liboqs-based authentication and key exchange into TLS 1.3 in our fork of BoringSSL; see https://github.com/open-quantum-safe/boringssl.
  • OQS-OpenSSH: A prototype integration of liboqs-based authentication and key exchange into Secure Shell (SSH) version 2 in our fork of OpenSSH; see https://github.com/open-quantum-safe/openssh.

Several demos are available for using the above libraries in applications, including Apache, Chromium, curl, haproxy, nginx, and Wireshark. Performance of liboqs in several settings is measured at https://openquantumsafe.org/benchmarking/.

liboqs can also be used in the following programming languages via language-specific wrappers:

Release notes

This is version 0.7.2 of liboqs. It was released on August 21, 2022.

Security considerations

This release removes Rainbow level 1 and all variants of SIDH and SIKE due to cryptanalytic breaks of those algorithms. Users are advised to move away from use of those algorithms immediately.

What's New

This release continues from the 0.7.1 release of liboqs.

The goal of this release is to provide a final release for algorithms that were included in Round 3 of the NIST Post-Quantum Standardization project. As the security status of some algorithms changed during Round 3, it drops algorithms known to be broken as of release (Rainbow level 1, SIKE). Some algorithms also updated their specification during Round 3; version 0.7.2 does not incorporate any algorithm changes that result in different input/output behaviour compared to version 0.7.1; such changes will included in version 0.8.0.

The next release of liboqs, version 0.8.0, will remove some algorithms that did not advance beyond NIST Round 3, update implementations based on algorithm/specification revisions that happened during Round 3, and begin to incorporate Round 4 changes. Discussion of algorithms to be removed in version 0.8.0 can be found in #1245.

Key encapsulation mechanisms

  • Kyber: Update implementation and switch use of symmetric crypto to OQS common code
  • HQC: Fix build on gcc-12
  • SIKE: Remove SIKE due to break (https://eprint.iacr.org/2022/975)

Digital signature schemes

  • Dilithium: Add ARMv8 optimized implementation and switch use of symmetric crypto to OQS common code
  • Picnic: Update implementation
  • Rainbow: Remove Rainbow level 1 due to break (https://eprint.iacr.org/2022/214)

Other changes

  • Add support for building on powerpc64
  • Update XKCP implementation
  • Improve SHA2 implementation on ARMv8
  • Improve AES implementation on ARMv8
  • Add aarch64 CPU feature detection on FreeBSD
  • Improve cross-compiling on Windows
  • Enable integration of liboqs into other CMake-based projects
  • Increment shared object library version

Release notes

This is version 0.6.0 of liboqs. It was released on June 8, 2021.

What's New

This release continues from the 0.5.0 release of liboqs.

Key encapsulation mechanisms

  • Update Classic McEliece implementation
  • Bug fixes in SIKE
  • Bug fixes in HQC
  • Change unsigned char to uint8_t in KEM API
  • Fix wrong NIST level for Kyber768-90s

Digital signature schemes

  • Update SPHINCS+ to Round 3 version

Other changes

  • Improve random number generator when not relying on OpenSSL
  • Improve run-time and compile-time guarding of optimized code
  • Remove (unused) AES decryption code from common symmetric encryption code
  • Replace AES plain C implementation with a constant-time version
  • Update Windows cross-compiling toolchain
  • Build options changed:
    • By default, liboqs is now no longer built by default with CPU runtime feature detection and thus resulting executables may crash if not compiled suitably for the CPU on which the code shall be executed. For Docker files, we recommend setting OQS_DIST_BUILD to obtain code able to handle different CPU feature sets. Also, OQS_OPT_TARGET can be used to target a specific CPU at compile time. These flags are documented on the build options wiki page.

Release notes

This is version 0.5.0 of liboqs. It was released on March 10, 2021.

What's New

This release continues from the 0.4.0 release of liboqs. Its main goal is to incorporate updates submitted to Round 3 of the NIST Post-Quantum Cryptography Standardization Project.

Deprecations

As a result of NIST's announcement of Round 3 of the Post-Quantum Cryptography Standardization Project, the 0.4.x series was the last release of liboqs to contain algorithms from Round 2 that are not Round 3 finalists or alternate candidates. Those algorithms have been removed in the 0.5.0 series. The algorithms in question are: NewHope, ThreeBears, MQDSS, and qTesla.

Key encapsulation mechanisms

  • BIKE: No changes.
  • Classic McEliece: Added AVX2 implementation.
  • FrodoKEM: Incorporate upstream bug fixes and add runtime CPU feature detection for AVX2/AES-NI implementation.
  • HQC: Update to Round 3 version.
  • Kyber: Update to Round 3 version.
  • NTRU: Incorporate upstream bug fixes.
  • NTRUPrime: Add NTRUPrime.
  • Saber: Update to Round 3 version.
  • SIKE: Update to version 3.4.

Digital signature schemes

  • Dilithium: Update to version 3.1.
  • Falcon: Update to Round 3 version.
  • Picnic: Update to Picnic v3.0.4.
  • Rainbow: Update to Round 3 version.
  • SPHINCS+: Incorporate upstream bug fixes.

Other changes

  • Support for building liboqs with CPU extensions has been enhanced, and most implementations now have runtime CPU feature detection.
  • A tool for benchmarking memory usage has been added (test_kem_mem and test_sig_mem).
  • Valgrind is used to check for secret-dependent branch throughout the library. Note that not all implementations currently avoid secret-dependent branching; see tests/constant_time for details.

Deprecations

As a result of NIST's announcement of Round 3 of the Post-Quantum Cryptography Standardization Project, the 0.4.x series will be the last release(s) of liboqs that contain algorithms from Round 2 that are not Round 3 finalists or alternate candidates.
