SUMSIG: Compact Code-Based Signatures from Sum-Check Protocols https://eprint.iacr.org/2025/2331
Debrup Chatterjee proposed SumSig, a code-based digital signature scheme leveraging sum-check protocols to reduce repetition reliance, achieving negligible error via single extension field verification, with signatures ~5-8KB. Debrup Chatterjee在论文中提出了SumSig，一种基于编码的数字签名方案，利用Sum-Check协议减少对重复的依赖，通过单次扩展域验证实现可忽略的误差，签名约5-8KB。
Notes
- SumSig uses sum-check protocols to replace repetitive Σ-protocols, reducing signature generation reliance.
- Achieves negligible error via single extension field verification without repetition.
- Signature size ~5-8KB, public key 50-100KB, offering different trade-offs.
- Based on Syndrome Decoding problem with quasi-tight reduction in random oracle model.
- Provides new choice in signature/public key size compared to Wave and LESS.
- First public version; feedback welcome, focusing on post-quantum cryptography.
