SPHINCS: Practical Stateless Hash-Based Signatures.
ADVANCES IN CRYPTOLOGY - EUROCRYPT 2015, PT I(2015)
摘要
This paper introduces a high-security post-quantum stateless hash-based signature scheme that signs hundreds of messages per second on a modern 4-core 3.5GHz Intel CPU. Signatures are 41 KB, public keys are 1 KB, and private keys are 1 KB. The signature scheme is designed to provide long-term 2(128) security even against attackers equipped with quantum computers. Unlike most hash-based designs, this signature scheme is stateless, allowing it to be a drop-in replacement for current signature schemes.
