ISARA Radiate Security Solution Suite Signature Edition 1.5

The ISARA Radiate Security Solution Suite provides a set of cryptographic primitives that let you develop software resistant to attacks by quantum computers. These primitives include:

  • Hash algorithms:

    • BLAKE2b (256 bit and 512 bit)

    • SHA2 (Secure Hash Algorithm 2; 256 bit, 384 bit and 512 bit)

    • SHA3 (Secure Hash Algorithm 3; 256 bit and 512 bit)

  • Message authentication codes:

    • HMAC (Hash based Message Authentication Code)

    • Poly1305

  • Random number generators:

    • HMAC-DRBG (HMAC Deterministic Random Bit Generator)

    • SHAKE (128 bit and 256 bit)

  • Digital signature schemes:

    • Dilithium

    • HSS (Hierarchical Signature Scheme)

    • Rainbow

    • XMSS (eXtended Merkle Signature Scheme)

  • Symmetric cipher:

    • ChaCha20 symmetric

Change Log

This is the first release of the Signature Edition.

Changes Since 1.4

New features:

  • HSS and XMSS now support the BDS tree strategy, resulting is significantly smaller private keys and a separate state at the cost of more processing time during Sign() operations. There’s also a verify-only strategy for efficiently verifying signatures.

  • HSS and XMSS now support detaching subsets of the private key’s state; this lets you split the range of one-time signatures. Refer to the Developer’s Guide for details.

  • Rainbow now supports six variants.

  • The library now supports a watchdog callback for long-running operations.

  • Library version information is now exposed in iqr_version.h, and a function has been added to verify that your library matches the headers you’re using. The version sample demonstrates this.

  • Hash: SHA2-384

Changed features:

  • The signature scheme formerly known as LMS is now HSS, and is compatible with the IETF draft. Currently only one level of hyper-tree is supported.

  • HSS implementation updated to version 13 of the IETF draft specification.

  • XMSS is now compatible with the IETF RFC.

  • HSS and XMSS now manage their own state rather than requiring the user to manage an index. This state needs to be stored safely after every Sign() operation (or every Detach() operation if you’re splitting state).

  • Rainbow key generation is now significantly faster.

  • Several algorithms have been updated to be compatible with the NIST competition submissions: Dilithium, Rainbow

Contents

The toolkit is organized into several directories:

  • doc — API documentation (doc/library/index.html) and Developer’s Guide (doc/guide/guide.html).

  • include — toolkit headers.

  • one or more lib_cpu directories — toolkit static and shared libraries optimized for the given CPU family.

  • samples — Sample programs demonstrating how to use the toolkit.

Getting Help

The latest version of the toolkit documentation is available on ISARA’s website:

For information about reporting security issues, please read the SECURITY document.

Using the Toolkit

After unpacking the toolkit archive, you can start using it by adding the following command-line arguments to your compiler:

-I/path/to/isara_toolkit/include \
-L/path/to/isara_toolkit/lib_cpu \
-liqr_toolkit_signature

where cpu is one of the available CPUs in your archive. For example, the linux archive includes these versions of the libraries:

  • lib_core2 - Intel Core 2 CPUs

  • lib_sandybridge - Intel Sandybridge CPUs

  • lib_skylake - Intel Skylake CPUs

  • lib_x86-64 - 64 bit AMD and Intel CPUs

Note
 If you’re linking against the shared library, you will need to link against the math library (-lm option).

If you require a version of the library tuned for a specific CPU, please contact ISARA’s sales team.

Building the Samples

Note
 Before building the samples, copy one of the CPU-specific versions of the toolkit libraries into a lib directory. For example, to build the samples for Intel Core 2 or better CPUs, copy the contents of lib_core2 into lib.

To build the samples:

cd /path/to/isara_toolkit/samples/algorithm/sample_name
cmake .
make

For more details and tool requirements, please refer to the Developer’s Guide (doc/guide/guide.html) documentation.

Note
 Don’t build the samples on macOS using gcc 8, they will crash before main() due to a problem with -fstack-protector-all. Use clang to produce Mac binaries.
