Use cases

Six scenarios, three modes

Where Confium is already the right shape — from threshold TLS signing to institutional Sovereign PKI.

Mode 1 — Peer-to-Peer TC

Distributed custody

Multi-party computation wallets and threshold key escrow. No single party holds the full key. Thunderbird-style backup generalized.

Web3 custody

Multi-party computation wallets and threshold key custody for blockchain applications. No single party holds the wallet key.

Mode 2 — PKI Drop-in

Web TLS signing

Threshold TLS signing via the Confium OpenSSL 3.0 provider. Replace single-key TLS terminators with multi-party signing without touching the application.

Code signing

Multi-stakeholder code signing. No single maintainer holds the full signing key. Confium orchestrates threshold signing across maintainers.

Email security (S/MIME)

Multi-stakeholder S/MIME signing for high-value email. Threshold key per mailbox; no single party holds the private key.

IoT device attestation

Threshold firmware signing and device identity attestation for IoT deployments. Firmware updates require multi-party sign-off.

Mode 3 — Sovereign PKI

Sovereign PKI

Institutional PKI where no single party is trusted. Calibration registries, pharma approvals, accreditation, supply-chain provenance, treaty orgs.

Document signing

Multi-stakeholder signing of contracts, PDFs, Office documents, and legal records. No single party holds the signing key.

Government identity

National IDs, passports, eID, and visa stamping with multi-stakeholder signing. No single government agency holds the root key.

Healthcare records

HIPAA-compliant signing of medical records, prescriptions, and clinical trial data. Threshold signing per record.

Financial settlement

Multi-party signing for trade settlement, SWIFT messages, and audit trails. No single operator holds the signing key.

Academic credentials

Verifiable diplomas, transcripts, and certifications issued under multi-stakeholder governance. No single administrator holds the issuing key.

Timestamping service

RFC 3161 timestamp authority with multi-stakeholder governance. No single operator can backdate or omit timestamps.

Long-term archival

RFC 4998 Evidence Record Syntax with multi-stakeholder governance and OTS Bitcoin anchoring. Signatures verifiable for centuries.

Cross-mode

PQ migration

Migrate from classical to post-quantum signatures without re-issuing every certificate. Composite signatures, software-only upgrade path.

Supply-chain provenance

Manufacturing step attestation anchored in a public transparency log. End-to-end provenance from raw material to consumer.
