liboqs nist-branch snapshot 2018-07

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.

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.

Release notes

This snapshot of nist-branch was released on July 27, 2018. Its release page on Github is https://github.com/open-quantum-safe/liboqs/releases/tag/nist-branch-snapshot-2018-07.

What's New

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

New key encapsulation mechanisms

The following KEMs have been added in the 2018-07 snapshot release:

• LEDAkem: 9 parameterizations: LEDAKEM_C1_N02, LEDAKEM_C1_N03, LEDAKEM_C1_N04, LEDAKEM_C3_N02, LEDAKEM_C3_N03, LEDAKEM_C3_N04, LEDAKEM_C5_N02, LEDAKEM_C5_N03, LEDAKEM_C5_N04 (contributed by Shravan Mashra (University of Waterloo))

New signature API and schemes

liboqs nist-branch now includes support for signature schemes via the API described in src/sig/sig.h; the API is based on the NIST and SUPERCOP APIs. Signature schemes can be tested using ./test_sig, benchmarked using ./speed_sig; example_sig contains a minimal example of using the signature API.

The following signature schemes have been added in the 2018-07 snapshot release:

• Picnic: 6 parameterizations: picnic_L1_FS, picnic_L1_UR, picnic_L3_FS, picnic_L3_UR, picnic_L5_FS, picnic_L5_UR (contributed by Christian Paquin (Microsoft Research))
• qTESLA: 5 parameterizations: qTESLA_I, qTESLA_III_size, qTESLA_III_speed, qTESLA_p_I, qTESLA_p_I (contributed by Christian Paquin (Microsoft Research))

Fixes

• Automatic detection of binutils version for BIKE build (contributed by Maxime Anvari)

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/9.
