OOPS: One-time Oblivious Polynomial Signatures https://eprint.iacr.org/2025/2340
Gurkan et al. propose OOPS, a one-time oblivious polynomial signature scheme based on pairing-based elliptic curves, supporting secure signatures for up to n messages, with applications in delegatable signatures, 1-out-of-n oblivious transfer, and partially oblivious PRFs. Gurkan等人在论文中提出了一种基于配对椭圆曲线多项式的一次性遗忘多项式签名方案OOPS，支持最多n个消息的安全签名，并展示了其在可委托签名、1-out-of-n遗忘传输和部分遗忘PRF等协议中的应用。
Notes
- OOPS is built on polynomials over pairing-based elliptic curves, securely signing up to n different messages.
- Signing more than n messages allows forgery under given parameters, requiring occasional reparameterization.
- Supports delegatable signatures, enhancing signature functionality flexibility.
- Enables 1-out-of-n oblivious transfer, improving privacy protection.
- Supports partially oblivious PRFs, balancing computational efficiency and privacy needs.
- Demonstrates OOPS's potential in various efficient cryptographic protocols.
