Abstract: ABSTRACT System for Offline Verification of Post Quantum Certificates and Permission Credentials The invention relates to a system for issuance and offline verification of post-quantum signed certificates and permission credentials in distributed edge environments. A unified cryptographic core, implemented in Rust and compiled into native, C-ABI, and WebAssembly formats, performs all hybrid composite and pure post-quantum signature verification. Customer-facing SDKs are designed as zero-cryptography shims, communicating with a local agent over a loopback API, with correctness established through a conformance manifest of signed fixtures. Entitlements are issued as deterministic permission slips, compiled by a control plane and detached-signed by a token engine, remaining valid for defined offline periods. Tokens embed self-carrying post-quantum key certificates attested by a long-lived root key of a distinct algorithm family, enabling offline validation of ephemeral signing keys. Entitlement enforcement is fail-open, governed by cached slips, with revocation effected by issuance starvation and restoration through resynchronization. The invention ensures resilience, continuity, and compliance in post-quantum environments.
