Single-Server Private Outsourcing of zk-SNARKs https://eprint.iacr.org/2025/2113
Abbaszadeh et al. proposed a single-server private outsourcing zkSNARK framework, which utilizes EMSM primitives to reduce client computation by 20 times, and protect witness and proof privacy. Abbaszadeh等人在论文中提出了一种单服务器私有外包zkSNARK框架，通过EMSM原语实现客户端计算降低20倍，并保护见证和证明隐私。
Notes
- Proposed a single-server private outsourcing zkSNARK framework, which utilizes EMSM primitives to reduce client computation by 20 times, and protect witness and proof privacy.
- Supports mainstream zkSNARKs such as Nova, Groth16, and Plonk
- Reduces client computation by 20 times and decreases proof latency by 9 times
- Implemented and evaluated the construction, verifying practicality and performance improvements
- Security depends on LPN variants, ensuring information leak during outsourcing
