Abstract: Disclosed is a kiosk-based multi-authority approval system for threshold generation and verification of multivariate quadratic group signatures in institutional approval workflows. The system comprises a plurality of approval kiosks, each having a support housing, a credential interface, a data input interface, a cryptographic processor, and a communication interface. The cryptographic processor accesses an authority-specific multivariate quadratic trapdoor and generates a partial multivariate quadratic signature component after validation of an authority credential. A threshold combiner receives partial multivariate quadratic signature components from different approval kiosks and generates an anonymous group signature only when components are received from at least a predefined threshold number of approval kiosks. A verification unit verifies the anonymous group signature using a group public multivariate quadratic key without disclosing participating authorities. A trace authorization interface permits identity disclosure only upon receipt of trace authorization inputs satisfying a trace threshold condition.
