SPHINCS+-SM3:基于SM3的无状态数字签名算法
SPHINCS+-SM3:SM3-Based Stateless Digital Signature Scheme
摘要
Abstract
SPHINCS+is a stateless hash-based digital signature scheme.In November 2022,the National Institute of Standards and Technology(NIST)announced that SPHINCS+will be standard-ized,and has started the discussion of the parameter selection.The security of SPHINCS+relies solely on a variant of the(second)pre-image resistance of the underlying hash functions.Hash-based signature schemes are believed to be the most conservative signature designs with respect to security.At the Fourth PQC Standardization Conference,Dustin Moody from the NIST PQC team stated in the report"NIST PQC:Looking into the future"that,SPHINCS+is selected for its solid security and it is based on a different set of assumptions from lattices.This paper instantiates the SPHINCS+framework with SM3,provides two sets of parameters fulfilling the level-1 security specified in the NIST PQC call for proposals,and presents some results of preliminary performance test.关键词
