Understanding the Identity-Transformation Approach in OIDC-Compatible Privacy-Preserving SSO Services
The UppreSSO system introduces identity transformations using elliptic curves to create privacy-preserving Single Sign-On (SSO) services compatible with OpenID Connect (OIDC). It prevents tracing by hiding user and Relying Party identities through complex mathematical functions, linking these transformations directly to Oblivious Pseudo-Random Functions (OPRFs) for enhanced security.
