liboqs nist-branch snapshot 2018-11


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.

This branch of liboqs (nist-branch) focuses on incorporating submissions to the NIST Post-Quantum Cryptography standardization project. Details about nist-branch can be found in README.md. See in particular limitations on intended use.

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

  • OpenSSL 1.0.2: A prototype integration of liboqs-based key exchange into TLS 1.2 in our fork of OpenSSL 1.0.2; see the OQS-OpenSSL-1_0_2-stable branch of our OpenSSL fork's repository.
  • OpenSSL 1.1.1: A prototype integration of liboqs-based key exchange and authentication into TLS 1.3 in our fork of OpenSSL 1.1.1; see the OQS-OpenSSL-1_1_1-stable branch of our OpenSSL fork's repository.
  • OpenSSH 7.7 portable 1: A prototype integration of liboqs-based key exchange into SSH in our fork of OpenSSH 7.7; see the OQS-master branch of our OpenSSH fork's repository.

Release notes

This snapshot of nist-branch was released on November 13, 2018. Its release page on Github is https://github.com/open-quantum-safe/liboqs/releases/tag/nist-branch-snapshot-2018-11.

What's New

This is the fourth snapshot release of liboqs nist-branch.

New key encapsulation mechanisms

The following KEMs have been added in the 2018-11 snapshot release:

  • Titanium: 4 parameterizations: Titanium-CCA-std, Titanium-CCA-med, Titanium-CCA-hi, Titanium-CCA-super (contributed by Ben Davies (University of Waterloo))

The BIKE implementation was updated.

New signature schemes

The following signature schemes have been added in the 2018-11 snapshot release:

  • CRYSTALS-Dilithium: 3 parameterizations: Dilithium_II_medium, Dilithium_III_recommended, Dilithium_IV_very_high (contributed by Tancrède Lepoint)

The qTESLA implementation was updated with a new upstream version (2018-07-28).

API changes

  • The public and private API have been more clearly delineated. The public API is now deemed to consist of oqs/common.h, oqs/oqsconfig.h, oqs/kem.h, oqs/rand.h, and oqs/sig.h and is marked with OQS_API.
  • An alg_version field is present on the OQS_KEM and OQS_SIG objects to indicate the version of the algorithm present.


Future work

Snapshot releases of nist-branch will be made monthly. Plans for the next snapshot release of nist-branch can be found online at https://github.com/open-quantum-safe/liboqs/projects/10.
