Lehmann et al. proposed a modular framework for anonymous credential systems, using core components and pluggable modules to support pseudonyms, range proofs, and device binding, improving standardization and security. Lehmann等人在论文中提出了一种匿名凭证系统的模块化框架,使用核心组件和可插拔模块支持伪名、范围证明和设备绑定等功能,以提升标准化和安全性。
Notes
Modular framework reduces redundant work, improving standardization of anonymous credential systems
Core components include commitments, signatures, and NIZK schemes, supporting pluggable extensions
Modules such as pseudonyms, range proofs, and device binding are independent of input, enhancing flexibility
Implementation using BBS signatures and ECDH, solving legacy hardware binding issues
Framework suitable for digital identity and privacy pass applications
