Optimization for SPHINCS+ using Intel Secure Hash Algorithm Extensions
Abstract
SPHINCS+ was selected as a candidate digital signature scheme for standardization by the NIST Post-Quantum Cryptography Standardization Process. It offers security capabilities relying only on the security of cryptographic hash functions. However, it is less efficient than the lattice-based schemes. In this paper, we present an optimized software library for the SPHINCS+ signature scheme, which combines the Intel® Secure Hash Algorithm Extensions (SHA-NI) and AVX2 vector instructions. We obtain significant speed-up of SPHINCS+-128f-simple on both non-optimized (70%) and AVX2 reference implementations (8% -23%) offering 128-bit security.
