区块链的领域特定后量子签名

中文摘要 AI 辅助

区块链需要的不仅仅是后量子单签名者签名。它们需要具有规范字节的共识配置文件化认证对象、定价的无效输入拒绝、稳定的交易标识符、混合降级抵抗、公共聚合、合并语义、可问责的签名者证据、前向安全的委员会轮换以及轻客户端后果。我们主张为区块链角色提供领域特定的后量子签名，类似于哈希函数工程为哈希表拒绝服务攻击和算术化证明系统产生了领域特定原语。我们形式化了交易授权和法定人数证书要求，在比特币、以太坊和Sei Giga风格的高吞吐量BFT压力配置上实例化它们，并评估了ML-DSA、SLH-DSA、Falcon/FN-DSA、HAWK、MAYO、SNOVA、UOV/QR-UOV、FAEST、SQIsign、LaBRADOR Falcon、Squirrel、Chipmunk和DKKW/LeanSig。结论是直白的。NIST单签名者签名是必要的组成部分，尽管目前的方案都不是现代公共区块链签名层的直接替代品。缺失的对象是一个共识就绪的后量子签名配置文件，而不是另一个通用大小表。

英文摘要

Blockchains need more than post quantum single signer signatures. They need consensus profiled authentication objects with canonical bytes, priced invalid input rejection, stable transaction identifiers, hybrid downgrade resistance, public aggregation, merge semantics, accountable signer evidence, forward secure committee rotation, and light client consequences. We argue for domain specific post quantum signatures for blockchain roles, analogously to how hash function engineering produced domain specific primitives for hash table DoS and arithmetized proof systems. We formalize transaction authorization and quorum certificate requirements, instantiate them on Bitcoin, Ethereum, and a Sei Giga style high throughput BFT stress profile, and evaluate ML-DSA, SLH-DSA, Falcon/FN-DSA, HAWK, MAYO, SNOVA, UOV/QR-UOV, FAEST, SQIsign, LaBRADOR Falcon, Squirrel, Chipmunk, and DKKW/LeanSig. We find that NIST single signer signatures are necessary components, yet none of the current schemes is a sufficient drop in replacement for the signature layer of modern public blockchains. The missing object is a consensus ready post quantum signature profile, not another generic size table.
