Master Thesis Project | ECDSA Zero-Knowledge Credentials in Yivi’s EUDI Wallet
Found on werkenbij.caesar.nl · last checked today
About this role
Master thesis project focused on designing and implementing a zero-knowledge credential architecture based on ECDSA cryptography for Yivi's evolution into a compliant EU Digital Identity (EUDI) wallet. The project addresses the challenge of integrating ECDSA-signed credentials (commonly used in JWT and mDL/MDOC formats) with privacy-preserving zero-knowledge proof techniques while maintaining Yivi's core principles of minimum disclosure, unlinkability, and user control. Work involves analyzing standardized credential formats (W3C VC, SD-JWT-VC, ISO 18013-5), presentation protocols (OpenID4VCI/VP), and privacy-enhancing cryptographic mechanisms to create a crypto-agile solution compatible with the EUDI ecosystem.
What you'll likely bring
- Strong understanding of cryptographic primitives, particularly ECDSA, zero-knowledge proofs, and selective disclosure mechanisms
- Familiarity with verifiable credential standards and formats (W3C VC, SD-JWT-VC, ISO 18013-5 mDL/MDOC)
- Knowledge of OpenID4VCI and OpenID4VP protocols
- Understanding of privacy-preserving cryptographic techniques such as BBS+, CL signatures, and related mechanisms
- Experience with digital identity systems and EUDI wallet requirements
- Ability to design and implement cryptographic architectures
- Research and analysis skills for evaluating cryptographic trade-offs
